Excel Data>Sort Issue

[Rob_010101]

Hello

Wondering if an Excel expert can help.

I'm wondering if this might be due to an update but i'm not entirely sure. I have a workbook at work which is used to track absence. There is a master data sheet which is refreshed with a system report every day, so on the absence sheet, all the employee's job titles / locations etc are kept up-to-date (via a vlookup from the master data sheet)

The absence sheet has about 5000 rows, the majority of these are filled with blanked formulas using =IF(OR(ISBLANK(N2)), "", VLOOKUP(@XXXXXX)) from column A to M. an employee ID is then added to column N and the employee's data will pop up in the columns before. This is excellent and does just the job we need it to.

Up until recently, however, a Data>Sort>Cell Values>A to Z would only sort the rows where the blanked formulas had returned values. So, I have about 500 rows of absence, where all the values are showing column A to M. Now, it wants to sort the blanked formulas with the 500 rows of returned values, meaning that whilst the data is sorted correctly, it lands up right at the bottom of the 5000 rows.

This happened suddenly out of the blue, so i'm not sure if it's a setting someone has changed, or an update to Excel that is causing this.

Kind Regards
