Shorten String Length If Exceeds 31 Characters (max Sheet Name Length)

Mar 27, 2014

I've set up a filing system which saves sheets/ workbooks based on the value of a cell - Range("B1") Everything works great apart from when ThisFile String length exceeds 31 characters which you may know is the max useable character length for a sheet name - I had no idea! 8-0

Is there a way i can check if string length exceeds 31 characters then, if it does, shorten it to 31 characters?

Give Cell A Value Based On Length Of Row (variable Row Length)

Jan 9, 2010

My worksheet contains data with the reaction times on a psychological test. Each respondent in the test has 280 rows in my excel sheet.

The 'perfect' length of the row, is from A to M. When an error is made in the test, the length of the row will increase. So the error length can be A to AA.

For me it is important to analyse the error. So I would like to give a perfect row length, the value 1, and an error row length a value 2.

So, in conclusion:

If:
Cell length = A1 - M1? --> Copy A1 B1 C1 (A B Cof that row) to Sheet3, and give D1 in sheet 3 the value 1

Cell length >= A1 - M1? --> Copy A1 B1 C1 (A B C of that row) to Sheet3, and give D1 in sheet 3 the value 2

VBA Code For Resizing Arrows To Specified Length?

Jun 7, 2013

I have created this Excel schedule that is attached. The point of the schedule is to organize Jobs and Crew members. I have VBA code in, so when I calculate how long the job should take, the arrows next to the job will automatically extend. (This should all make sense if you take a look at the attachment.) The only problem is that my arrows do not extend the correct distance. In the attached file I have scheduled "James Lorenz" to do a job starting on tuesday, towards the bottom of the page I did my calculation that figures he should be on that job for 9.5 days. I would like the Arrow next to James' job to extend 9.5 days on the calender instead of 9.5 centimeters or whatever it is doing now.

Find The Median Call Length For Calls In A Certain Month

Dec 13, 2006

I've read several threads about using Median(If, and I have success with one criteria, but not with three. Here's the setup:

I have a log of phone calls, and I want to find the median call length for calls in a certain month or set of months (i.e. a quarter, three months). In Calls!B I have the date of the call, in Calls!C I have the call length in minutes (i.e. "34"), and in Calls!A I'm using Concatenate and Text to return month/year (i.e. "Aug06").

With one criteria, it calculates the median correctly. With three, it only returns #NUM. Yes, I hold control+shift and hit enter. Here's my formula:

=MEDIAN(IF(Calls!$A$2:$A$500=Scores!B8,IF(Calls!$A$2:$A$500=Scores!C8,IF(Calls!$A$2:$A$500=Scores!D8,Calls!$C$2:$C$500)))))
Where Scores!B8,C8,D8 hold "Oct06" "Nov06" and "Dec06" respectively. What am I doing wrong? Is there another approach I should use instead?

Character Length Formula - Add Trailing Spaces

Feb 11, 2013

Is there a fomula that can add trailing spaces. For example....I need a certain feild to be 11 Characters in length. So lets say in Column A, I have a bunch of different words:

House
Bird
Up
Down
Yes
No

I would like to put a formula in column B that takes my original text and adds blank spaces to the end of it until it's 11 Characters. So "House" in Column A would be "House " in column B.

Limit Text Length In Cell With Formula By Data Validation?

Jan 25, 2014

Can I limit the text length in a cell that contains a formula? You may say "Limit the text length in the input cell". That can't be done because the formula in the resultant cell takes text from two other cells in addition to the input cell. I need to limit the overall text length to, let say, 50 characters.

I'm receiving this statement when trying to save:

"One or more formulas in this workbook are longer than the allowed limit of 8192 characters. To avoid the limitation, save the workbook in the Excel 2007 Binary workbook format."

The longest formula is 29 characters long. Even if I add the number of characters in every formula in the workbook, it only adds up to 1664.

Cell Length Display

Oct 12, 2009

I have a worksheet in Excel 2007. I have "wrap text" turned on in column G and so long as the character count doesn't exceed 255 the text will wrap and display properly. However, when the number of characters in a cell of column G exceed 255 the display in the cell turns to all pound signs (#). The content of the cell is displayed in the URL line but it is all # in the cell. How can I fix this?

Fixed String Length

Dec 1, 2009

I am trying to create a string of text that grabs info from other cells, which is easy so for example

=A1&A2&A3

would grab all the info from the 3 cells and merge them to create a string, but what I want to do is create a prefixed length.

Lets say A1, A2 and A3 would equal 10 characters in total but B1, B2 and B3 would equal 7 characters, these would be different lengths. so for a visual description I would like them to appear like this

At the moment

01MAIN-HELLO
01DESSERT-HELLO WORLD

Would like

01MAINXXX-HELLO
01DESSERT-HELLO WORLD

This would make both strings the same length and would make it easier for me to export to a custom file that needs a certain length prefix.

Sum Of Variable Length Ranges?

Jun 20, 2014

So I have got an identifier and a corresponding column of values. I need to calculate sum of those corresponding values for each identifier, so if identifier is 1993, I need to have a sum of all the corresponding values. These identifiers repeat, and I do not want to calculate sum for all of them, just the immediate identifiers (i.e. you have 1993, after that you may have 1994 etc etc and then at one point you will have 1993 again, but that "new" 1993 will have a different sum of course). Also, identifiers do not go in sequence sometimes (however, most of the case they do), for example 1993 may jump suddenly to 2004. The trick with all of this is variable "row width" of these identifiers...

Replacing Any 0 Length Cells With A Value

Nov 30, 2011

I have been using this code below to replace any blank cells with the number 0 but recently I have encountered an error if the format of the cell is a string.

Code:

Range("A1").Select
Range(Selection, Selection.End(xlDown)).Select
Range(Selection, Selection.End(xlToRight)).Select
Selection.SpecialCells(xlCellTypeBlanks).Value = "0"

Is there a way to change this so it looks at the length of the cell, if the length of the cell is 0 then set the value = 0?

SUM A Column With Unknown Length

Jun 26, 2012

Trying to sum up a column that has an unknown length. This is a canned Excel form that is saved within a software system and is used to create customized documents. Usually, I would enter the table name.field name in a cell to pull the data from various parts of the system.

In this case, that data resides in AA234 of my customized Excel sheet. When the user retrieves this doc from the system, the data could run several rows, starting from AA30 to AA255. So, in my "Total" cell, I've entered =SUM(AA1:AA255), so it will just add up whatever is in the column, regardless of how long it runs upon document generation. When I try to pull the document, I get "=SUM(#REF!)" in that field instead.
