I am the owner of a webshop and have to import over 5000 products. Now in the last month an excel file has gone corrupt, causing big problem to my company.
We work from a private cloud (my cloud) in which we save the files. all of a sudden the file will not open and generates the following error:
"Excel cannot open the file 'filename.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension.
The error code is 101590.
To possible recover the file i tried to an excel repair tool, but this got the following result:
All bytes in a file "the file name" are equal to 0 (zero). Program can not recover anything from empty file.
What could be the cause of the file going corrupt?
Help is much appreciated and needed for my starting company.
