Compare Two Columns, If Missing Insert Missing Data

Jul 8, 2008

I have two columns which i want to compare, they contain text data such as A123.

what I'd like is if its in column A and not in Column B then add to bottom of column A.

Once its in column A i can do the vlookup's to draw the other data, costs etc, over but don't know how to identify, and add, the missing codes to the list.

I'm sure this query has been answered somewhere else but I can't seem to find it. I basically have information in two worksheets in the same workbook which need to be compared and the missing values from one worksheet need to be listed in a message. There are duplicate values in both worksheets so only need a list of the unique missing values. For example:

Sheet1 Column A 1 2 1 5 5 2 3 5 4

Sheet2 Column A 2 3 3 4 3 4

The message box should state that we are missing 1 and 5 from the dataset as it is not in Sheet2. If the list could be sorted in ascending order that would be great too.

I have two list of names, mostly duplicates. List in column B has about 30 more names than the list in Column A and I need to identify which names are in column B that are not in column A. Names are in exact same format since they were pulled from the same data base.

I am currently using MS Excel 2007. Is there a way in VBA to automatically insert missing columns based on a defined series or range of values?

For example, we have a report that displays columns of: Year 2004 to Year 2012 per column (9 columns in total). Sometimes, it displays missing a year or years (thus; our report has less columns). For example, it only shows 2008 to 2012 (missing 2004 to 2007). At times, it misses some years in between. What we do is manually add those missing years by manually inserting columns then inputting the missing year as their column headers.

Is it posisble for VBA to check if the columns contain all of the defined Year range (for example, you've initially defined: Year 2004 to Year 2012)? Afterwards, all missing columns are automoatically inserted (in chronological order or based on your defined values or range).

I have 2 worksheets that need to be merged. More specifically, I have one 'master' XLS file with some columns included in it that are missing from a second XLS file. I need to merge the new columns (with column titles in row 5) into the second 'auxilary' sheet without touching data above row 5.

I have one excel 2010 workbook with 5 work sheets, each work sheet contains a list with first/last name(one column) and the company name, some have a 3rd column with their email address in each sheet represents each year starting at 2008 thru to 2013 i have to find out if the people that attended an event in 2008 also attended it in 2009/10/11/12/13 and if they didnt, put their name and company name onto a blank worksheet within the same workbook without using a macro, how can i do this?

I have data in 2 workbooks. Book1 - Sheet1 - Col A and Book2 - Sheet2 - Col A. I want to compare Book2 with Book1 and list all values in Book2 that do not find a match in Book1. I want to run a macro for this

is there a formula I could use to compare two similar lists to determine what is missing, for example an old list of 200 lines and another of 275 lines, with a first column containing unique ID code.

I would like to compare email addresses for dupes and add missing PIN number in Column F Sheet 1 from Column F in sheet 2. Is this feasable and relatively simple? I have enclosed a test example as teh acutual scenario has thousands of entries.

I am looking for help. Sheet1 B1:1 has dates in each column in ascending order for one month. There are missing dates in between the days and they might look like this.

Example 1

7/1/20097/2/20097/6/20097/7/2009

Is there a code that will insert columns with the missing dates between the dates that already exist so that example 1 would become example 2?

We recently bought some new software at work, and I'm having trouble formatting the exported data in a way that will work with existing reports. The attached file is what the data looks like after being exported. Basically, what I'm trying to do is insert rows for the missing numbers -- i.e., each name should be followed by rows numbered 1 through 10.

John Smith John Smith 1 1 4 2 8 3 4 5 6 7 8 9 10

My ultimate end goal is to have columns of data for each name, instead of rows:

John Smith 1 2 3 4 5 6 7 8 9 10

I've created a formula that can do that part, but it operates on the assumption that each name will be followed by a set number of rows.

What little I know about vba I've learned on my own, so I may just be missing something obvious.

I have a sequence(or a series is more proper) of dates(without the hours) for. exapmple: 10/22/2007,1025/2007,10/25/2007. What I need is to insert rows with the missing dates. I found a VBE code for a macro which does the work but now the problem is that in some rows the dates are the same and if I have two times 10/25/2007 it adds the row with the next date after the first one and all messes up.

Range("A2").Select Do Until ActiveCell.Value = Empty If ActiveCell.Value = ActiveCell.Offset(-1, 0).Value + 1 Then ActiveCell.Offset(1, 0).Select Else ActiveCell.EntireRow.Insert ActiveCell.Value = ActiveCell.Offset(-1, 0).Value + 1 ActiveCell.Offset(1, 0).Select End If Loop

I am trying to insert the missing numbers/rows on a numerical acsending column. I have a spreadsheet that has a list of 8000 parts that I want to put into numerical acsending order, however numbers are missing. For Example:

Column A is a numerical part number and column B is the description for the part number in column A. My spreadsheet used to be in perfect numerical order however over the years some rows have been deleted which makes my spreadsheet look like the below example.

ColumnA ColumnB 1 -------Part A 2 -------Part B 3 -------Part C 5 -------Part E 6 -------Part F

As you can see part number 4 is missing is there a way to insert the missing part numbers into column A and keep column B in order associated with column A? My goal would have the result look like this below.

ColumnA ColumnB 1 -------Part A 2 -------Part B 3 -------Part C 4 5 -------Part E 6 -------Part F

I am looking for a quick solution for this as there are 8000 rows. I have tried the MATCH function and can't seem to get that to work.

The excel file has industrial information arranged by sector. The sectors are represented by six digit codes that are not strictly sequential. For example, a typical example of consecutive codes is 120011,120012,120030,120040,130011. There are upwards of three hundred sectors.

The data I am using is missing certain sectors - sometimes more than 30 at a time. I would like to find a quick way to identify the missing sectors and insert rows there, preferably with the first cell in the row being the missing sectoral code.

I have a similar problems with columns as well. But I can always just transpose the data and use whatever solution works for the rows.

I am processing an infinite set of data from a meteorological station here in Alaska which gives me half hourly data reading with a time stamp 00.00, 00.30, 01.00, 01.30, 02.00, 02.30 and so on.

I am using this formula to detect every time half hour reading is skipped (=IF(TEXT(MOD(B1936-B1934,1),"[M]")="30","","missing")) and it works pretty well. Still I have to check and manually insert extra missing for every half hour missing but that's bearable.

This formula inserts a "missing" every time it finds a gap.

My question is: How can I insert a row above every cell with "missing"?

I have tried many different ways of coming up with a solution of this problem without writing a VBA program, however, Excel's date and time formatting scheme seem to be tripping me up. As a result, I am trying to figure out what direction to go.

I have seached the board up and down looking for a solution and I have found one problem that is midly similar but I do not fully understand the code. I have tried to modify it but to no avail.

Here is my problem:

I have 9 columns of data that are reported in 15 minute intervals for a little over 3 years. There are missing data in the data set and it would be infeasable for me to manually find and replace the missing data. (Over 110000 rows of data)

Example of data (Where "/" delienates column seperation):

Date / Temp 2m / Temp 10 m / Radiation / RH / WindAve / WindMax / WindMin / Rain

So what I need to do is this: 1) Find which data times are missing 2) Add the appropriate amount of rows in between where the missing data would be 3) Add the correct dates to the new rows 4) Add "N/A" to the columns that have no data

You can see that my date and time are formatted in mm/dd/yy hh:mm

I found this on the website and was trying to modify it to my needs:

I am trying to import data from web to excel. I posted the link below to the website I am attempting to import from. The only part I need is the statistics. However, I cannot get it come thru by getting external data from web.

The goal is to great an auto updating spreadsheet with multiple sheets so copy and paste is not feasible.

I have ben given a excel file from another department at work as they had been told i know a bit about excel. Excel... Yes, Visual Basic... Nil, zilch, nada! It really might as well be written in chinese!!

What has happened is the guy who set this up has since been made redundant from the company and they now want the file to do one more thing.

Basically what they want the file to do is, when the user clicks the 'generate file' button, if E2 has no date entered then a message box pops up stopping the user from going any further until a date is entered.

I need to be able to create an average total that skips any missing information. For example, if I have four values I need the average for all four (e.g. 5+6+7+3/4), but if one is missing I need the average of three (e.g. 5+7+3/3).

I found the array formula: =AVERAGE(IF($A$1:$A$50,$A$1:$A$5)) [Note: I pressed Ctrl+Shift+Enter to make it an array formula]. Which works perfectly for cells that are next to each other (e.g. A4:W4). The trouble I am having though is that the cells I need to pull the data from are not next to each other e.g. (K4, N4, S4, W4).

I did try to ammend the array formula with the following: =AVERAGE(IF($K$4,$N$4,$S$4,$W$40,$K$4,$N$4,$S$4,$W$4)). But of course that came back with a "too many arguments" error.

How can I ammend this information to make this formula work.

Extra information if needed: The cells that have missing data are not blank or have a 0 value, they show a "#N/A" (which doesn't need fixing).

Is there a way to flag data that hasn't been used in another worksheet. For example, a second worksheet consolidates the data into two different groups, but someone spelled the name of one of the groups wrong in the first worksheet and the data was not added via a sumif function.

I have a list of numbers in sequential order. There are numbers missing. Is there a way to have Excel insert rows for the numbers that are missing in the series.

I have created a user form for some data submission. I am looking for a macro to check the text boxes, that I have named appropriately i.e. Name, Address, City, State etc. , to make sure there is something entered.

If nothing is entered it needs to return a msgbox that says what field is blank.

I have a pivot table based on a sales sheet called "Datasheet". I have created the pivot table using a dynamic name as below =OFFSET(DataSheet!$A$1,0,0,COUNTA(DataSheet!$A:$A),12). My problem is that I have 11100 lines of sales data but the when i refresh my pivot table it only seems to be going down to row 10979. Therefore missing out some of the data. Is there a max number of lines for a dynamic named range or is my formula wrong in any way

I have been searching the forum for weeks now for an solution to my need, but was unsuccessful. I have two Workbooks. One is for tracking new enrollments in the school for whom I work named WVT.xls and the other is for tracking the school materials assigned to each student named 2007.xls (for inventory accounting). I need to streamline adding new enrollments names to both Workbooks by adding to only one manually and then using VBA code to update the names in the other workbook. The sequence would be to type the names into WVT.XLS and run a macro in 2007. XLS to automatically update the names. Below is the locations of the same named columns in each workbook.

First Name Last Name WVT.XLS Column B Column A

2007.XLS Column B Column C

In 2007.XLS, there is a sheet for each school location that is represented by a unique school code. In WVT.XLS, there is one sheet for all enrollments from the start of distributing materials. Each row is a student. There is a column that contains the unique school code to identify in which school the student has enrolled.

Any easy way to retrieve data from another table using an array formula.

I have two files that I am using that contain 2 sets of data with columns for name, address, city, and state. The red highlighted data needs be used to find the blue data first column, which is a possible name for the company found from the red data. The issue is that the blue data is larger and has rows of data that will not be found in the other table.

I have the spreadsheet attached. I attempted to use an if/and statement : =IF(AND(D2=C8I:I,E2=J:J),H2,0) but found out that it does not work with arrays and only found the first address by default.

How would I set up a formula to retrieve the possible names using criteria from the blue data such as if the address and city match, then input that company name?

I have 2 sheets in the same workbook (sheet 1 & 2) with one matching column (A) of info and need them to combine and fill the missing data. Each sheet has identical column heading and the amount of data is not the same; sheet 1 has ~2000 rows and the other ~5000. Sheet 1 is consolidated so I would like to fill in the missing cells from sheet 2.

Ex. Sheet 1.......

Ex. Sheet 2.....

As you can see, the missing cells in sheet 1 could be filled from the data in sheet 2; also note that the above info is on different rows (and will be random for each case). I only want the columns to fill in that have a matching email, the other 3000 rows in sheet 2 do not match with sheet 1 and I don't want the rest of it to transfer over.
