Just use LO 4.4 calc merge not in excel

I have file from excel (.xlsx), when im edit with calc everything look good, just like before. but when data/file being open again with excel all merge on cell gone, like never been edited. can anyone tell me why???

Can you save the original xlsx-file after editing in Calc in ods-format?

Alternatively can you try the same LibO 4.3 version?

If you have a Windows PC you can download the portable version 4.3.5 and make a test. http://www.libreoffice.org/download/portable-versions/

You also can upload the file here to allow a look into your file. However, be aware that this is a public forum.

yes i can save xlsx file from calc… the problem appear when the file reopening with excel…
but that not happen when i use LibO 4.2 or 4.3 before…
now i use LibO 4.2.7 again (default linux mint repos)
