Created attachment 121780 [details] Excel Error Screenshot Hello, I'm using 5.0.4.2 on Windows 10 and opened an Excel 2003/2007 file in Calc. When I had finished working I saved in in Excel format. When I tried to open it in Excel 2010 I got errors about missing data. Please see the attached screenshot. I can't upload the whole sheet as it's my business accounts, but I'm happy to upload any other information required. Thanks
Please try anonomize data in document, see https://wiki.documentfoundation.org/QA/FAQ#How_can_I_eliminate_confidential_data_from_a_sample_document.3F or try to create new test file. Attach excel's log file - appears on error message, the xml file. Thank you
Tried it in Office 2016 and it seemed to open without errors.
