I had lost my data and tried to recover data from different tools and fortunately, I retrieved the lost data back with a new error message. When I tried to open, any excel file I got the following error message. I have tried many solution to resolve this problem but still unsuccessful. I need your help to fix this issue as soon as possible. Thanks.
The file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
Excel cannot open any file that contains data recovered after being lost
There´s a real little chance you´ll be able to make this work! coz you´ve deleted the file already and depending on the usage you´ve give then hard drive you might ´ve already written something on it already! I highly recommend trying recovering the files again but with this software, Recover MyFiles. I use this to make recoveries of lost or hidden files! Takes a bit but it works!
You can also by actually changing the file extension! Coz by the looks of it does not have any… After the name of the file while you rename it, Put .xls!
Let me know if you need any more help!
