Final answer:
To remove the last three characters in an Excel cell, use the formula =LEFT(A1, LEN(A1) - 3), combining the LEFT and LEN functions, where A1 is the cell containing the original text.
Step-by-step explanation:
To remove the last three characters from a cell in Excel, you can use the LEFT function combined with the LEN function. The LEFT function allows you to extract a given number of characters from the start of a text string. The LEN function returns the length of a text string. Here's the formula you would use:
=LEFT(A1, LEN(A1) - 3)
This formula assumes that your original text is in cell A1. It calculates the length of that text string and then subtracts 3 from that number, effectively telling the LEFT function to leave out the last three characters.
As an example, if cell A1 contained the text 'ExcelData123', the result of the formula would be 'ExcelData', with the '123' removed.
