How do I fix 'Excel found unreadable content' error?

This error occurs when Excel's internal XML files are corrupted. The Basic Scanner automatically repairs the corrupted metadata, shared strings, and relationship files that cause this error. Simply upload your file and download the repaired version.

What file types and sizes does the free Excel repair tool support?

The Basic Scanner supports .xlsx and .xlsm Excel files up to 10 MB in size. These are the modern Excel formats that use the Office Open XML (ZIP-based) structure. Older .xls files (Excel 97–2003 format) are not currently supported.

Is my data safe when I upload Excel files?

Yes. Uploaded files are processed in memory and immediately deleted from servers once the repair is complete. Files are only retained if you explicitly opt in by checking the 'Share File For Further Analysis' box. The service never shares, sells, or provides files to third parties, and all data is transmitted over encrypted HTTPS connections.

How long does the repair take?

Most files are analyzed and repaired within a few minutes. The process is entirely browser-based—you upload your file, the AI scans the internal XML metadata, fixes structural issues, and returns a repaired version for download. No software installation or waiting in a queue is required.

What if the Basic Scanner can't fix my file?

The Basic Scanner fixes approximately 80% of corrupted files by repairing metadata and structural issues. For severe corruptions such as damaged pivot tables, macros, charts, or deep structural damage, the upcoming Advanced Scanner will handle these complex cases with a 95%+ success rate. You can join the waitlist to be notified when it launches.

Fix My Excel File is a free, browser-based Excel repair service that analyzes and fixes corrupted .xlsx and .xlsm files. When Excel files become corrupted, it is usually because the internal structure—relationships, formatting definitions, content types, and other metadata—has become invalid. The AI-powered scanner examines each metadata file within your Excel ZIP package, identifies structural issues, and repairs them automatically, handling approximately 80% of corrupted files.

The Basic Scanner is completely free with no installation, payment, or account required. It validates ZIP archive format, repairs XML syntax, fixes workbook structure, relationship files, shared strings, styles and formatting, calculation chains, document properties, content types, and theme files. Files are processed securely in memory and immediately deleted from servers unless you opt in to share them for analysis.

For severe corruptions involving pivot tables, macros, charts, and deep structural damage, an Advanced Scanner is coming soon as a paid, one-time-per-file service. The service also offers free step-by-step guides for manual XML-level repair when automated tools cannot help.
