ODS file has a format error

[elijahs]

A ODS file (118kb) when trying to open gives me a error message. "Format error discovered in the file in sub-document content.xml at 2,501726(row,col)". I tried using the fixes in this forum but can't even get into seeing the content step. Guess I'm too old (78) and my memory is full. Lol Lost count on how many different computer office programs and CAD systems I have learned over the years being a Design ME. I think what happened is that I shutdown pc before file was fully closed.
Would very much appreciate if someone could fix this. Thank You

I think what happened is that I shutdown pc before file was fully closed.

Hundreds of people have had their files corrupted doing that. Always give the operating system plenty of time to save a file to disk. How long? Depends on your hardware and operating system.

Would very much appreciate if someone could fix this.

The file seems to be badly damaged, and I don't see any way to repair it. Restore from a backup, if you have one.
Read section 6. Saving your data and making backups in Ten concepts that every Calc user should know.

Switch to LibreOffice and this will be less likely to happen to you in the future. There are several good reasons for making the switch, some of which are mentioned here: [Tutorial] Considering a Switch from OpenOffice to LibreOffice? Some Useful Information

There is an outside (i.e., unlikely) possibility that you may be able to find a deleted work file. Download one of Recuva or Photorec and tell that to make an indepth search of your hard drive for hidden/deleted temporary files.
