Facing trouble in saving work data in Excel 2019.

[NurHasan9]

Scenario: After converting the sheet data into Excel table or Pivot table, or if I am doing some analysis using Pivot table and charts, though I am saving it before closing the Excel program, but still not getting all of those works and I realized that somehow, it's not saving my work.

Please help me to solve this issue.

Did you save it as an xlsx-, xlsm- or xlsb-file?

Thank you so much.

I got the problem in Excel safe mode, the file was saved in CSV format so I had to save it in the workbook.
