Bug ID: 144431
Summary: Calc files saved as .xlsx cannot be opened by Excel
365
Product: LibreOffice
Version: 7.1.6.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
I just installed Excel from Microsoft 365. I have several .xlsx files created
with LibreOffice Calc, using version 7.0.6 and 7.1.6. When I try to open these
files in Excel, it says they are corrupt and will not allow opening. If I
rename a file extension to .xls and try opening again in Excel, it says it may
be corrupt and asks if I want to open it anyway and then lets me open it. If I
rename the file extension to .ods, Excel is able to open it with no errors.
To sum up, for the following Calc created files:
.xlsx - Excel gives an error and cannot open
.xls - Excel gives an error and then allows opening
.ods - Excel opens without any problem
Obviously this is a problem for sharing spreadsheet files between a mix of
LibreOffice and Excel users.
