This checker focuses on common file-side PPTX problems: unreadable presentations, repair warnings, wrong extensions, damaged package data, or another Office file type.
What ARADURU checks inside your PPTX file
A PPTX file is a ZIP-based Office package. ARADURU checks the package and important PowerPoint structures instead of judging the file only by its extension.
Can the Office package be opened?
Checks whether the selected file can be read as a modern Office package.
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 whether the package identifies its internal presentation parts.
Are the main package relationships readable?
Checks the root relationship file that connects the package to its primary presentation parts.
Does the real file type match PPTX?
Distinguishes supported PowerPoint, Word, and Excel Open XML packages.
Can the presentation and slides be read?
Checks the main presentation XML and whether PowerPoint slide parts are present.
The diagnosis comes before the XML details
ARADURU summarizes what the result means first. Individual package, XML, and slide checks stay under Technical details.
No obvious PPTX structure problem found
The core Office package, presentation XML, and slide structure did not reveal an obvious structural failure.
The PowerPoint file needs attention
The package may be readable but have a wrong extension, another Office type, or a structural warning.
An important PPTX check failed
Missing or unreadable package parts can indicate a damaged or incomplete copy.
A healthy structure does not rule out every presentation problem
ARADURU does not validate every image, video, font, animation, embedded object, link, or PowerPoint-specific behavior.
- Keep the original. Test repair or conversion attempts on a copy.
- Try Microsoft PowerPoint or another trusted PPTX viewer.
- Get a fresh copy. Re-download or re-request the presentation if needed.
- Do not rename to convert. Changing another extension to .pptx does not create a valid PowerPoint file.
Your selected PPTX stays in your browser
The current checker analyzes the selected PPTX locally in the browser and does not upload the presentation to the ARADURU server. The current beta may load JavaScript libraries from a third-party CDN, but the selected presentation is not sent to those library servers by this checker.
Common PPTX file-check questions
Can ARADURU repair a damaged PPTX file?
No. This checker diagnoses supported file-structure problems and suggests next steps. It does not rewrite or repair the selected presentation.
Why can a PPTX look healthy here but still fail in PowerPoint?
This check focuses on the Office package and presentation structure, not every media object, feature, or application-specific behavior.
Can ARADURU detect a Word or Excel file renamed as PPTX?
Yes. For supported Office Open XML packages, ARADURU can distinguish PPTX, DOCX, and XLSX.
Can it detect a PPTX with the wrong filename extension?
Yes. If the internal package is recognizable as PPTX, ARADURU can report the extension mismatch.
Does the checker upload my PowerPoint presentation?
No. The selected presentation is processed locally in your browser and is not uploaded to the ARADURU server.
