Users may be unable to upload SDLXLIFF files to TMS or rebuild them offline in SDL Trados Studio 2017/2019  if they were created from certain version of XLSX files using Microsoft Excel 2007-2013 File Type.
 

Since SDL TMS 11.4 , TMS contains Microsoft Excel 2007-2016 File Type a newer version for XLSX file types.  All configurations should be re-configured to use this latest file type.

There is other possible workaround that may work in most cases.

•    Download the source XLSX file to your local computer
•    Open the source XLSX file with an earlier version of Microsoft Excel (2013 and earlier)
•    Save the XLSX file
•    Create a new job with new XLSX filw. 

You can still test your XLSX  file in SDL Trados Studio 2017/2019  using  both file types : Microsoft Excel 2007-2013 and Microsoft Excel 2007-2016 File Type  to see if the file is extracted and if target file be rebuild,  before creating a job in TMS.
 

This may happen when the XLSX source file has been created in an unsupported version of Office, more specifically the Microsoft Office/Excel 2016 build number 1707 and newer. Excel files created in Microsoft Office 2016 are not officially supported by the Microsoft Excel 2007-2013 File Type.

You can see what Microsoft Excel application version a given XLSX was last edited with by checking the AppVersion value inside the XLSX file (you will need to rename the *.XLSX to *.XLSX.ZIP): 

YourExcel.xlsx/docProps/app.xml
<AppVersion>16.0300</AppVersion> 
 

• MS Excel 2007: <AppVersion>12.0300</AppVersion> 
• MS Excel 2010: <AppVersion>14.0300</AppVersion> 
• MS Excel 2013: <AppVersion>15.0300</AppVersion> 
• MS Excel 2016: <AppVersion>16.0300</AppVersion>
