This checker focuses on common file-side DOCX problems. It can help distinguish a readable Word package from a file with a wrong extension, damaged package data, missing required parts, or unreadable document XML.
What ARADURU checks inside your DOCX file
A DOCX file is a ZIP-based Office package. ARADURU checks the package and its important Word structures instead of judging the document only by the .docx filename.
Can the Office package be opened?
Checks whether the selected file can be read as the ZIP-based package used by modern Word documents.
Does the package data pass integrity checks?
Runs CRC32 verification on practical file sizes to look for damaged archive data.
Are Office content types present?
Checks the package definition that tells Office applications what kinds of parts are stored inside.
Are the main package relationships readable?
Checks the root relationship file that connects the Office package to its primary document parts.
Does the real file type match DOCX?
Detects whether the internal package is actually Word, Excel, or PowerPoint and compares it with the filename.
Can the main Word document XML be read?
Checks whether word/document.xml exists and contains parseable XML for the main document body.
The practical diagnosis comes before the XML details
You do not need to understand Office package paths. ARADURU explains the likely file-level problem first, while the individual package and XML checks remain available under Technical details.
No obvious DOCX structure problem found
The core Office package and main Word document XML were found without an obvious structural failure.
The Word file needs attention
The package may be readable but have a wrong extension, another Office type, or a structural warning.
An important DOCX structure check failed
Missing or unreadable package parts can indicate a damaged, incomplete, or incorrectly labeled copy.
A healthy package does not rule out every Word problem
ARADURU checks the basic DOCX package and main XML structure. A document can still fail because of unsupported Word features, problematic embedded objects, macros in another format, permissions, security settings, application-specific errors, or corruption outside the checks in this version.
- Keep the original. Test recovery or conversion attempts on a copy.
- Try Microsoft Word or another trusted DOCX viewer. Application-specific errors may reveal more detail.
- Get a fresh copy. Re-download or re-request the document if it came from email, cloud storage, or a transfer.
- Do not rename to convert. Changing another extension to .docx does not create a valid Word document.
Your selected DOCX stays in your browser
The current checker analyzes the selected DOCX locally in the browser and does not upload the document to the ARADURU server. The current beta may load JavaScript libraries from a third-party CDN, but the selected document is not sent to those library servers by this checker.
Common DOCX file-check questions
Can ARADURU repair a damaged DOCX file?
No. This page diagnoses supported package and XML problems and suggests next steps. It does not rewrite or repair the selected Word document.
Why can a DOCX look healthy here but still fail in Word?
This check focuses on the basic Office package and main document XML. It does not validate every embedded object, style, relationship, feature, or application-specific behavior.
Can ARADURU detect an Excel or PowerPoint file renamed as DOCX?
Yes. For supported Office Open XML packages, ARADURU checks the internal structure and can distinguish XLSX, DOCX, and PPTX.
Can it detect a DOCX with the wrong filename extension?
Yes. If the internal package is recognizable as DOCX, ARADURU can report that the current filename extension does not match the actual Word document type.
Does the checker upload my Word document?
No. In the current version, the selected document is processed locally in your browser and is not uploaded to the ARADURU server.
