Applying Formulas To Large Number Of Dates
Mar 17, 2009
i have a spreadsheet with a certain data (rate of return) associated to a specific day of a year. (ex. 8-dec.-08 0.99865), and i have to calculate the rate of return (r) for every month, which is done by applying a formula (GEOMEAN) to all the rate of returns for the days of a month (ex. GEOMEAN(r[01 dec.]:r[31 dec.])).
i don't have any problems with that part. the hard part is that i have every single trading day from jan 00 to dec 08 (2000+ days), and i do not want to manually select the ranges. also, the dates do not include weekends (trading days per year = 252) which means that i cant (a) automatically determine a range or (b) automatically associate a number of days to a month (ex. oct 08 doesn't have the same amount of days as oct 07, because of the way week-ends and holidays are arranged..)

I I have a excel document which has a sheet containing a large number of array formulas.
I turned the automatic calculation off.
However, even when I press F9 to calculate the cells it just crunches, gets stuck at “Calculating 0%” and then crashes.
The majority of the array formulas are IF queries with multiple criteria.
Would it speed up the calculation if I didn’t use array formulas?

Any way to apply a formula to a cell depending on what choice is made from a drop down box in a cell that it refers to.
Hypothetically:
I have a drop down box in A1 with 2 options: Cookie Making Costs - or - Cake Making Costs
In cells A3 through A10, I have cells with the costs for all the ingredients (and B3 through B10 for cake ingredients).
If I select Cookie Making Costs, I would like B1 to apply a formula that sums up all the costs associated with making cookies "=sum(A3:A10)"
If I select Cake Making Costs, I would like B1 to apply the sum of the cake ingredients "=sum(B3:B10)"

how do I apply a formula I entered into one cell to all the cells in that column, without going through the tedious process of typing the formula in again in each cell ? I've done it before but don't remember how.

i was wondering if there was a way i can combine these two formulas into one large one
=IF(AF8="","",INDEX($A$3:$A$102,AGGREGATE(15,6,(ROW($L$3:$L$103)-ROW($L$3)+1)/($L$3:$L$103=AF8),COUNTIF($AF$8:AF8,AF8))))
=IF(AG8="","",INDEX($A$3:$A$102,AGGREGATE(15,6,(ROW($M$3:$M$103)-ROW($M$3)+1)/($M$3:$M$103=AG8),COUNTIF($AG$8:AG8,AG8))))

So in Cell K12 there is a rather large formula (I condensed it for this example).
This formula is to average out the respective cells in column J. For each cell there is a possibility of 9 different entries. NRT, N/O, 1,2,3,4,5,6,7
So based on the formula in K12 I need Cell J12 to Display the answer.
if any one of the Cells referenced in the formula are NRT then I need it to Display NRT. Which the Formula does now.
The problem comes in when a Cell is N/O (Not Observed)
How do I get the formula to Ignore N/O currently I have it set up to recognize N/O as 0. But excel averages 0 in and it affects the answer.
I know in a simple formula I can add <>0 to the formula to ignore zeros. How to write it into a bigger formula such as in K12.
For example the current numbers in Cells J17:J25 should average 5 however the formula averages it as 1 because it calculates N/O as 0.

I am trying to calculate a matrix of array formulas that is roughly 365 x 137, or about 50,000 cells being calculated from a range of roughly 12,000 x 137. There are multiple if statements within the array formula, and then those 50,000 cells are referenced to another, but smaller matrix of array formulas (25 x 137). Each of these matrix sets is for one year, and there are three years that need calculated.
Problem: When calculating the 50,000 cells it takes roughly 2.5 hours to complete all calculations. So, for 3 years it will take roughly one work day of tying up my computer to just compile data that will then require several days of calculation/manipulation.
Question(s): Is there a way to speed this up to a reasonable amount of time (I'd even take 30 minutes at this point)? Or, is Excel simply the wrong tool to be using for this amount of data? Do I need a better machine to run these calculations? I am currently using a Dell XT3 with 2.5 Ghz i5 quad core processor.

I am accustomed to using filters to find a lot of my information in large datasets.
However, now I am trying to use formulas to return specific values. For simplicity's sake, I have included a sample below with a couple types of scenarios I am looking to solve through the use of formulas. Would this involve sub-arrays perhaps?

how to return the top 5 results in a set of data.
In a nutshell, I have data that needs to be sorted but some intermediate to advanced (to me) excel formula needs to be used to sort the ranking properly. I've already used index, match and large but it does not suffice.

I have a range of purchase order rows, with the formulas stored in the first row (TemplateRow) which is hidden. The users may add any number of rows to this range, depending upon the number of different products being purchased.
Code:
'Copy the template row into the first newly inserted row
Rows(TemplateRow).Copy Destination:=Rows(insertionPoint)
'fill down from the inserted row down to the last new row
With Rows(InsertionPoint & ":" & NumberOfInsertedRows.Rows.Hidden = False
.FillDownEnd With
The problem is copying the formulas down to the new rows can take terribly long (minutes) in scenarios of thousands of products. Is there a faster method of copying down my formulas?

I'm new to creating macros and trying to create a macro that will perform a formula that I can use for multiple files. However the files are a varying number of rows.
I want the formula to carry out on the entire column (all rows). However when I record the macro (I tried using relative and also tried using absolute references when filling the formula) the formula always seems to stop filling wherever my original file's rows stopped. I wrote the formula for the first row and double clicked it to fill the remaining rows.
For example if the macro I recorded in File 1 goes to row 15, when I run the macro on File 2 which is 20 rows, the formula stops filling at row 15.

In cell G1 I have my snapshot dates header and dates running from G2 to G31. Next to in Column H I have the sold items by Product A.
There are 6 different snapshot dates and I need them to be horizontal with a formula and none duplicated with the largest (newest) date first so I can SUMIF the sold item per date. If I simply pull a LARGE formula it will return 24-05-2014 in all rows is it is the biggest "value".
When I them add new snapshots (biweekly) then the horizontal snapshot line will automatically add the newest dates (i.e. find the largest or newest, the 2nd newest snapshot, the 3rd newest, etc. Hence, in K2 we would have 09-03-2014 with 672 sold items in K3 (via SUMIF), in L3 we would have 18-03-2014 and 7523, in M3 23-03-2014 and 1703, etc.
I'm not sure if I explained it well enough. I'm attaching a file if this makes more sense.

If I have the numbers 1-50 repeating in columns, 1-50, 1-50 etc is there a way to determine that number "1" falls 1st, 51st etc in the sequence without doing a manual count? Or that the number 2 falls 2nd, 52nd etc?

I work in a factory where we create different types of units daily. Below is a list of planned production on a specific date, say today's date. This is a very crude example, with information missing, and it is important to know that there are conditions attached such as:
The types are added randomly. The amount of types is much greater meaning that each type is on it's own page with breaks between. Everything produced on this date will have a URN (unique reference number) with its first 6 digits equating to yy-mm-dd and the last two being the position of the unit in the production sequence (first=01, second=02 etc).
I have gotten it to the point where if you enter them in sequence (Type A first for example) it will lookup to see the last assigned URN and taking the quantity into account issue the correct URNs.
The issues I have are when the URNs are less than "10", there is a problem displaying the 0 before the digit which disrupts the sequence. I can provide more clear examples if required.

Here is my set up:
A2 to BF2 is a range of dates
A3 to BF3 are sales. Days without sales are 0.00
I want to pick a range of dates and find the number of days without sales between those dates. So, a formula that will look to a start date in A1 and an end date in B2, and then count the number of days that did not have sales between. Index/Match/Countif/Dateif I can't seem to make anything work.

I have problems in PASTING my 19 digit number from the source report into excel.
E.g, the original value is 8321515222222123122 but it always transfer to 8321515222222120000
I have tried the simple cell format setting, that is after pasting, I set the cells to text, but it doesn't help and also try the custom fomat "###################", but it is still the same result with the last 4 digit lost.
What I want the format to be is not in scientfic and have to be full display.

I'm trying to use conditional formulas with dates.
I have a list of employees that will get raises on November 1 of each year. The raise depends on their grade, which increases by one every year on the day and month they were hired.
I'm including my Excel file. For example I have one employee hired on January 16, 2012. As of today, his grade is 3. On Nov 1, 2014 he will still be on grade 3 (he won't advance to grade 4 until January 16, 2015). On Nov 1, 2015 he will be at grade 4 and on Nov 1, 2016 he will be at grade 5. Another employee was hired on October 15, 2013. His grade today is 1. On Nov 1, 2014, he will be on grade 2. What formulas can I put in the yellow cells to do these calculations?

The format of the numbers are:
####-##-###-####
I have 2000+ numbers is coloumn B.
There are a lot of sets of numbers that are still text! It's highly annoying and I need to analyze the data in Access.
I tried the paste special advice and the 3 ways microsoft suggests. I have a feeling its not working because of the required format that I need.
I need to do this project tonight!
Background: these are imported numbers, I had to combine other excel databases... By the way, is their an easier way to combine excel sheets into 1?

The following macro deletes blank rows in my project (I have a source sheet that I "transfer" information to various "law practice worksheets", and it works fine. However, once I get past a certain number of rows (my project will include 65,000 rows), the macro does not delete the blank rows any more from the "law practice worksheets" (I previously sent this spreadsheet to the Forum with another question that was not answered yet). Here is the macro for deleting rows:
On Error Resume Next
Sheets("InternatlLaw").Select
Range("A2:D65000).Select
Application.DeleteBlankRows = True
Selection.EntireRow.SpecialCells(xlBlanks).EntireRow.Delete
ActiveSheet.Range("A2:D65000").Select

Each sheet contains 30,000 rows of data in column A, C, E, G and I.
I want to find each cell of column A, C, E, G and I to another sheets column A, C, E, G and I respectively.
If match found then it should return "True" in column B, D, F, H and J.
I have tried VLookup, but it takes too much of time for calculation (1,50,000 vlookup Formulas needs to calculate in each sheet with If condition) some time calculation gives wrong results.
As well as I want to do filtering on this all the data... so that time calculation gives the problems (I have used application.Calculation=xlCalculationManual)
So now I am using Range.Find method, but that loop excecutes for 30,000 times and each ittration contains 5 Find methods.

I heard there is an efficient way of writing large amounts of data at once to a worksheet. My program is writing alot of data (e.g. 600+ items in each row) and takes over an hour to run because it writes to each cell one-at-a-time. I seached this forum and couldn't find the answer. Here is an excerpt from an old 1998 article by Dermot Balson and William Mercer that used code to write to cells in large chunks but it doesn't work for me - I get a method failed message.
'to read in
Dim A As Variant 'MUST be variant, no brackets
A = Range("SomeRange").Resize(10,20) 'reads 10x20 array starting at range SomeRange
'(NB I've used Resize above but you can specify a range of cells any way you want)
'to write back to sheet
Range("SomeRange").Resize(10,20) = A
'A can be any data type but MUST be two dimensional even if you are only writing one
'column or row - first dimension is used for rows, and the second for columns
'this can be slow - see third question below for workaround..
Here is the link to the article: http://www.avdf.com/apr98/art_ot003.html. A more detailed explanation how this trick works
