Excel within Microsoft Office Home and Student 2013 has suddenly stopped recognising basic formulae

Occasional Contributor

I have been using the same formula for years, but today all my Excel have stopped updating.

It is just account spreadsheet but today it will not recognise any new input after using this for 10 years plus. Also any other or even new spreadsheets won't update.

As variant your files are in manual Calculation mode


Thank you so so much. I have spent hours on this. All sorted now.
Many thanks.

@Brendan802 you are welcome, glad to help.

Just in case, if the latest closed file in the session was in manual mode, any file opened in next session also will be in manual mode. Doesn't matter is that your own file or you received it from other source.
