Let's say you want to find text that begins with a standard company prefix, such as ID_ or EMP-, and this text must be in uppercase letters. There are several ways to check if a cell contains text and the case of the text matters to you.
Compare one cell to another cell
To do this task, use the EXACT function.
Note: EXACT is case-sensitive but ignores formatting differences.
Compare one value to a list of values
Note: If you have a current version of Office 365, then you can simply enter the formula in the top-left-cell of the output range, then press ENTER to confirm the formula as a dynamic array formula. Otherwise, the formula must be entered as a legacy array formula by first selecting the output cell, entering the formula in the output cell, and then pressing CTRL+SHIFT+ENTER to confirm it. Excel inserts curly brackets at the beginning and end of the formula for you. For more information on array formulas, see Guidelines and examples of array formulas.
Check if part of a cell matches specific text
Note: The FIND function is case-sensitive.
The formula in the above screenshot uses the following arguments.
Formula to check for text
search_for: What you want to check for.
to_search: The cell that contains the text that you want to check.
