    File not opening due to extension error

    Need help in recovering very important file, the data file on which I was working yesterday is not opening today and believe me there was lot of work involved in compiling that file, can anybody please help me or guide to recover the file

    Below is the error message:

    "Excel cannot open the file DATA.xlsx because 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"


    Please urgent help needed.

    You have macro's in that file?

    In that case the exentions need to be .xlsm
    Notice my main language is not English.

    I appreciate it, if you reply on my solution.

    Then there is no need to change the extension.
