Truncating Data String

[theinfini]

First off, I apologize if this answer is somewhere else already, I have looked and have come up empty handed.

I have the following data that I am working with:

/mnt/p_inf01_10080_rrd
/mnt/p_inf01_10090_sunpower
/mnt/p_inf01_arb
/mnt/p_inf01_areva
/mnt/p_inf01_bm


I want a column with the text of each row that follows the last underscore, so: "rrd, sunpower, etc."

Any help on doing this would be greatly appreciated. I am learning VB to find avenues to accomplish my task. Thank you.

theinfini,

Welcome to the Excel Forum.

I assume that your raw data is in column A, beginning in cell A1.

Detach/open workbook GetLastString S array col A to B - theinfini - EF777117 - SDG15.xls and run macro GetLastString.



If you want to use the macro on another workbook:


Please TEST this FIRST in a COPY of your workbook (always make a backup copy before trying new code, you never know what you might lose).


1. Copy the below code, by highlighting the code and pressing the keys CTRL + C
2. Open your workbook
3. Press the keys ALT + F11 to open the Visual Basic Editor
4. Press the keys ALT + I to activate the Insert menu
5. Press M to insert a Standard Module
6. Where the cursor is flashing, paste the code by pressing the keys CTRL + V
7. Press the keys ALT + Q to exit the Editor, and return to Excel
8. To run the macro from Excel, open the workbook, and press ALT + F8 to display the Run Macro Dialog. Double Click the macro's name to Run it.

Then run the GetLastString macro.

@ stanleydgromjr

Why use VBa?

This would do exactly the same, and is more elegant than my original, rather protracted, suggestion.

Drag/Fill Down

[martindwilson]

yep i'm with marcol no vba needed
=TRIM(RIGHT(SUBSTITUTE(A2,"_",REPT(" ",100)),100))
but 100 is a tad excessive
=TRIM(RIGHT(SUBSTITUTE(A2,"_",REPT(" ",20)),20)) should cover it!

[stanleydgromjr]

Marcol,

I am learning VB to find avenues to accomplish my task.

Per theinfini.

Besides, I used the Substitute formula in the macro.

[futamura]

Marcol, Martindwilson,

=TRIM(RIGHT(SUBSTITUTE(A2,"_",REPT(" ",20)),20))

Quick question: Is there a way to make this work if there are (consecutive) spaces in the string?

[theinfini]

Marcol,

Thank you, that worked, but how. I tried "reverse-engineering" it (taking it apart piece by piece and watching the results to understand how it works) but I don't understand how substituting the underscore with 100 spaces removes the rest of the text. Is it a limit on text in an excel box?

Whatever the case is, I'm just glad it worked.

[Marcol]

By replacing the underscore in all instances with 100 spaces, and I agree with Martin this is somewhat excessive, we produce a string that is long enough to use RIGHT("the extended string",100) to return a string that will contain "all the rightmost characters" preceded by 100 minus "all the rightmost characters" spaces.
TRIM(RIGHT("the extended string",100)) removes all the leading spaces.

Not sure where the extra consecutive spaces comes into it, but the worksheetfunction TRIM() removes ALL extra spaces, unlike the VBa function which only removes leading and trailing spaces.

[EDIT]
You might want to reverse engineer my original suggestion for your own interest.
This works out how many instances of "underscore" are present in the string by replacing "_" with "", by subtracting the length of the modified string from the length of the original string we know how many "underscores" there are.
Using this information we can replace the last instance, or for matter, any single instance of "_" with some unlikely character, say "|" (Pipe), then use Mid() and FIND() to return the characters to the right of the chosen instance.
