How to open .XLTX files on Android
To open .XLTX files on Android, tap the .xltx in your file manager or email attachment and open it with Microsoft Excel if installed; it should generate a new workbook from the template.
Step-by-step instructions
- Tap the .xltx in your file manager or email attachment and open it with Microsoft Excel if installed; it should generate a new workbook from the template.
Common issues
Opening the template creates a new workbook instead of letting you edit the template
.xltx is a template format; spreadsheet apps often treat it as a blueprint and create a new workbook from it when opened.
- In Excel, use File → Open to open the template, then use File → Save As to save your changes back as a template (.xltx) if you intend to update the template itself.
- If you only need a normal spreadsheet based on the template, save the newly created workbook as a regular Excel workbook (for example, .xlsx) with a new name.
File won’t open or reports corruption
.xltx is an OOXML package of multiple parts; if the package or any required XML part is damaged, Excel may fail to open it or warn about repairs.
- Re-download or re-copy the file (corruption often happens during transfer or incomplete downloads).
- Try opening it in Microsoft Excel and allow repair if offered, then immediately Save As a new file name.
It opens in the wrong application
Operating system file associations can be set incorrectly, especially if multiple office suites are installed.
- Windows: right-click → Open with → Excel → set as default if desired.
- macOS: select the file in Finder → Get Info → Open with → choose Excel → Change All.
Security note
.xltx is the non-macro OOXML template type; macro-enabled templates are a different extension (commonly .xltm). If you expected macros, verify you received the correct file type.
