Excel Found Unreadable Content
Check the XLSX package, workbook, worksheets, relationships, styles, and shared strings for file-side problems that can contribute to unreadable-content warnings.
ARADURU checks file-side evidence in your browser first, then separates file problems from app or website problems.

Why Excel may report unreadable content
Unreadable-content warnings can be caused by specific workbook-structure failures, but the message does not automatically prove that the entire file is corrupted.
Malformed worksheet XML
A worksheet can exist in the package but contain XML that Excel cannot parse normally.
Broken workbook relationships
Sheet definitions may point to missing or unresolved worksheet targets.
Invalid supporting references
Style, shared-string, or worksheet-level relationship references can point to missing or invalid data.
How ARADURU checks this Excel problem
Validate the main workbook and worksheet XML that ARADURU currently supports.
Follow workbook-to-worksheet relationships and verify referenced internal targets.
Check supported style and shared-string tables only when the workbook actually uses them.
Report whether the file-side evidence is strong, possible, or absent for this Excel warning.
How to interpret the match level
ARADURU found concrete file evidence that can directly or strongly contribute to the selected Excel error.
ARADURU found a warning or structure problem that may be related, but the evidence does not prove the exact cause by itself.
The current structural checks did not reveal an obvious blocker. Continue troubleshooting outside the basic file structure.
What this check cannot prove
ARADURU cannot prove the exact cause of every Excel repair prompt. A workbook may use advanced features or application-specific behavior outside the current structural checks.
Common questions about this Excel problem
Does “unreadable content” always mean the workbook is ruined?
No. Excel may repair some problems, and a warning can also involve features outside ARADURU’s current structural checks.
What does a strong file-side match mean?
It means ARADURU found a concrete XLSX package, XML, or relationship failure that can plausibly contribute to the warning. It is evidence, not a guarantee of Excel’s exact internal diagnosis.
Should I repair the original file directly?
Keep the original unchanged. If recovery is necessary, work on a duplicate or obtain a fresh export from the source application first.
