XLSX File Won’t Open
Check whether the workbook has a detectable file-side blocker such as missing package parts, broken relationships, malformed worksheet XML, or a mismatched real format.
ARADURU checks file-side evidence in your browser first, then separates file problems from app or website problems.

A workbook can fail to open for more than one reason
ARADURU checks the file itself first. If the basic XLSX structure looks healthy, the next place to investigate may be Excel, access permissions, security settings, or a feature the current checker does not inspect.
Required workbook parts are missing
A readable ZIP container is not enough if xl/workbook.xml or its required relationships cannot be resolved.
A worksheet target is broken
The workbook can reference a sheet that is missing, malformed, or disconnected from its relationship ID.
The file is healthy at the basic level
If no obvious structural blocker is found, the cause may sit outside the file-side checks ARADURU performs today.
How ARADURU checks this Excel problem
Confirm that the file is actually an XLSX workbook and not another format with an .xlsx name.
Validate the core OOXML package, workbook, worksheet, and relationship chain.
Inspect supported style, shared-string, and worksheet relationship integrity.
Separate a concrete blocker from a warning-only condition or a healthy basic structure.
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
A healthy structural result is not a guarantee that Excel will open the file. Passwords, security policy, permissions, macros, advanced features, or application-specific failures can require separate troubleshooting.
Common questions about this Excel problem
Can ARADURU tell me exactly why Excel will not open the file?
ARADURU can identify supported file-side causes and explain their strength. It cannot observe Excel’s own runtime state, security policy, or every workbook feature.
What if the file is reported as structurally healthy?
That means the current package and XML checks did not find an obvious blocker. Continue with application, access, security, or feature-specific troubleshooting.
Why does ARADURU keep telling me to preserve the original?
Repair attempts can overwrite recoverable data. Keeping the original unchanged preserves the best recovery option while you test copies.
