How to Repair Excel Files Corrupted After Android Transfer
Question details
The user needs to recover an XLSX file that reports as damaged with illegal XML characters after being transferred from or edited on an Android device.
- Product
- Microsoft Excel
- Device & OS
- Android / Windows
- Scenario
- Editing a workbook using an Android application or transferring it via an Android SD card, resulting in a file that can no longer be opened normally in Excel on a PC.
- Observed behavior
- Excel displays an error stating the file is damaged, and the recovery log reports illegal XML characters in the /xl/sharedStrings.xml component, often stripping data from the worksheets upon attempted repair.
Before attempting any repair methods, create a backup copy of the corrupted .xlsx file so you do not accidentally overwrite or lose any remaining recoverable data during the troubleshooting process.
Extract Data Using Alternative Spreadsheet Software
Bypass Excel's strict XML validation by opening the file in a more forgiving spreadsheet application like Google Sheets or LibreOffice Calc to extract your data.
Since the corruption is often limited to a few unsupported characters in the sharedStrings.xml file, alternative applications can frequently ignore the error and render the intact data.
Navigate to Google Drive in your web browser, click the 'New' button, select 'File upload', and choose your corrupted .xlsx file.
Double-click the uploaded file and select 'Open with Google Sheets' at the top of the preview window.
Check the specific cells referenced in the original Excel recovery log and delete any unusual or unrecognized symbols.
Click 'File' > 'Download' > 'Microsoft Excel (.xlsx)' to download a freshly generated, error-free copy of your workbook.
Restore from a Cloud Backup
If the file was saved in OneDrive prior to the SD card transfer, you can restore a previous working version.
Open and Recover Corrupted Workbooks with WPS Office
WPS Office features robust document compatibility and can frequently bypass minor XML errors that cause Microsoft Excel to crash or reject files. Use WPS Office to safely recover your data and enjoy seamless cloud syncing to prevent Android SD card transfer issues.
- 1. Open the Corrupted File: Launch WPS Office Spreadsheets on your computer and open the damaged .xlsx file directly. WPS will attempt to bypass the illegal XML character error.
- 2. Locate and Fix Errors: Navigate to the cells mentioned in your previous recovery log and delete any strange symbols.
- 3. Save as a New Workbook: Go to 'Menu' > 'Save As', and save the file under a new name as a Microsoft Excel Workbook (*.xlsx) to rebuild a clean XML structure.
- 4. Sync Securely via Cloud: Save the file to WPS Cloud to access it safely on your Android device without relying on error-prone SD card transfers.
Frequently Asked Questions
Why does my Excel file show an illegal XML character error?
This error occurs when a third-party Android editing app or a faulty file transfer (such as moving the file via an SD card) introduces invalid or unsupported characters into the workbook's underlying /xl/sharedStrings.xml component, breaking its structure.
How can I prevent Excel files from corrupting during Android transfers?
Avoid physically moving files using SD cards or non-standard USB transfer methods. Instead, utilize cloud storage services like OneDrive, Google Drive, or WPS Cloud to sync files securely across your devices.
How do I read an Excel recovery log?
When Excel repairs a file, it displays a dialog box with a link to a log file. Click the link to open the XML log in your browser. Look for the specific 'Removed Feature' or 'Removed Records' lines to identify which specific cells or XML parts were removed.
Is it safe to use third-party Android apps to edit Excel files?
While many apps are safe, some lack strict adherence to the official .xlsx format standards. To prevent corruption, it is recommended to use highly compatible applications like WPS Office or the official Microsoft Excel app for Android.
