How to open .SXC files on iOS
To open .SXC files on iOS, iOS typically won’t open .SXC reliably in built-in viewers; transfer the file to a desktop and open it with LibreOffice Calc or Apache OpenOffice Calc.
Step-by-step instructions
- iOS typically won’t open .SXC reliably in built-in viewers; transfer the file to a desktop and open it with LibreOffice Calc or Apache OpenOffice Calc.
Common issues
The .SXC file opens as garbled text or in the wrong app
The file association may be incorrect, or the system may treat it as a generic XML/text file instead of a Calc spreadsheet.
- Open LibreOffice Calc or Apache OpenOffice Calc first, then use File > Open to select the .SXC file.
- On Windows/macOS/Linux, set the default app for .SXC to your spreadsheet suite via “Open with” / “Get Info” / file properties.
Error when opening or “file is corrupted” message
The file may be incomplete (bad download/copy), or it may not actually be an SXC spreadsheet despite the extension.
- Re-download or re-copy the file from the original source (avoid email clients that may alter attachments).
- Try opening the file with both LibreOffice Calc and Apache OpenOffice Calc to rule out a single-app compatibility issue.
Layout, formulas, or formatting look different after opening
Because .SXC is a legacy format, modern suites may import it with minor differences in formatting or formula handling.
- Check key sheets, formulas, and charts after opening, especially if accuracy is critical.
- If you need stable long-term editing, save a copy to a newer format from within the spreadsheet app and work from that copy.
Security note
.SXC is a spreadsheet format; treat it like any document from an untrusted source—malicious content may target application parsing or spreadsheet features.
