  • Hey there! Help pls. I use MacBook Pro…. The error ALERT.
    "The file format and extension of ‘ ‘ don’t match. The file could be corrected or unsafe. Unless you trust its source, don’t open it. Do you want to open it anyway?".
    I have installed two times the Excel application. But added to the frustration of using MS package on a MacBook.

    The Options are Yes or No. Clicking both options lead to MULTIIPLE FILES OPENING, REPEATEDLY WITH NO STOPPING. I have to force quit. No result.

    I use MACBOOK & have official Office 365 subscription.

    Clueless what to do & whom to seek help from….
    So, approaching you as favour.

  • I unchecked these options, but it didn't work for me. This error is common in the forums too. I read the solution of this forum: https://social.technet.microsoft.com/Forums/office/en-US/63020ccc-51d7-46d9-b956-121c0e6efcc8/excel-file-error-the-file-format-and-extension-dont-match and repaired my file using Excel repair software.
