How Can I programmitically compress files from XLSX in Excel's default compression? RRS feed

  • Question

  • I understand that XLSX format is just like zip format.

    rename it '*.zip' and decompress it.

    The other way,  compress it and rename it '*.xlsx'.

    it works.

    but file size is changed.

    when i resaved it, the file size returned as almost previous size.

    i think Excel's compression is different than other compression models.

    I dont't want to make this size changes.

    How can i compress extracted files in default compression level?

    or can i change Excel's compression settings?

  • Hi blacksmith01,

    you had mentioned that , you want to compress the file and make .zip files.

    but you don't want to decrease the file size when it get compressed.

    well, the word "compression" itself says that when you perform this operation it will decrease the file size.

    then also I try to test with different compression codes and find the similar results.

    so I think you can't make your desire changes , as you want by using compression.
