Comments on: Get rid of "The file is corrupt and cannot be opened" in Excel

Usually when upgrading you expect nothing but improvements. So it can be really disappointing when after moving to Excel 2010 you have no chance to access your xls. file. You understand what I’m talking about if you ever encountered the "The file is corrupt and cannot be opened" error in Excel 2010. Still think it can’t open? Actually it can! Continue reading →

  1. I have a similar problem, but nothing to do with an upgrade.

    I have a macro enabled file open in XL2003, which originated as an xlxs file from XL2010. Conversion to an xls file was straightforward. I then in 2003 added the macros. It is now saved as an xlsm file, and when XL2003 saves it is reports that the file is being converted.

    Until the latest changes to the macros, the file could be saved, closed and re-opened. Now the macros do all they should do, the file can be saved, but if I close it it cannot be opened. XL reports that the file is corrupt.

    I can go, and have gone, back to an older version (v3) to make the changes again. Which I have saved now as v5. v4 cannot be opened by XL2003 on the original machine (the machine that saved the file). v4 and v5 cannot be opened on a different machine by XL2010.

    I am reluctant to close v5 on the original machine until I know that I can open the saved version elsewhere.

    Does anyone have any clue as to what may have happened? I am at a loss. I understand file corruption, and that a corruption may occur during the save operation, but do not expect it to hit what is really the same file (the v3 file saved as v4 and v5) in the same way on two different occasions, so I have discounted any file system or OS corruption.

    It may be something introduced by the converter that XL2003 is using when saving the file, but I do not understand why the converter would add to the file something that XL2003 does not understand. But even if it did, I would then still expect a later version of XL (XL2010) to be able to read and open the file.

    Thank you

  12. Odd. Two machines in our office, and only one had this problem. The Trust Center settings were identical for both in both Word 2010 and Excel 2010. But one of them would not open downloaded files at all, always saying they were corrupt. Your solution did work, but it doesn't make sense that it's a problem on one machine and not the other.

    Anyway. Thanks!

I saved and closed the file, then about 3 hours later I went to open it and it said the file was corrupted and couldn't be opened. Also the date of the file was from the previous day not yesterday. I have tried all the online solutions I can find as well as yours and they do not work. At work I use Excel-2010 and at home I use Excel-2016 This is a very important file to me, Can you help?
