All the people in my sheets are adding data to different cells in different days and I want to know when they did them because difference between the registered data by different people is very important for me.

  • You can check the version history of the sheet. If this doesn't solve your problem, can you provide a sample with expected result, thanks. – pjmg Aug 7 at 8:47
  • The question is too broad. There are several means to view who changed what on a a spreadsheet. If you didn't review yet support.google.com/docs, please do it and if you need further help briefly describe why the built-in functions doesn't work for you or where you get stuck. – Rubén Aug 8 at 4:54
