Hi All, I have a excel.xlsx file saved in my system which has been corrupted .I atleast need to recover the data stores .It is a file of 124 KB and has around 35 worksheets in the workbook .I hav...
I face the same issue.
I have a xslx file with the name Schedule 2025. I have shared it with my team. I can open it through Sharepoint but I cannot open it from my pc.
I have tried to provide full access but problem remains. The file does not have any weird formats inside. It's quite simple. I don't want to delete the file and create a new one. I just want this one repaired.
The open and repair option is not helpful as I get the same error message
