FAQ

What file formats are supported?

• Word: .docx (not legacy .doc)
• Excel: .xlsx and .xls
• PDF: .pdf

Why does my URL preview fail?

Common causes:

1. CORS blocked — the server does not allow cross-origin requests
2. Private URL — the document requires authentication
3. Wrong format — the file extension does not match the actual content

Try uploading the file locally instead.

Is my document uploaded to a server?

No. File uploads are processed entirely in your browser. No document content leaves your device.

Can I edit documents?

No. This tool is preview-only. Use desktop Office software or online editors for editing.

Why can't I reload a file from history?

File upload history stores metadata only (filename, type, timestamp). You need to re-upload the file to preview it again. URL-based history entries can be reloaded directly.

Does it support PowerPoint?

PowerPoint (.pptx) preview is available in vue-office but not yet integrated in this tool. Support may be added in a future update.

Excel or fullscreen layout looks wrong?

After switching wide screen or fullscreen, the tool remeasures the container and refreshes the layout. If issues persist, exit and re-enter fullscreen, or reload the page and open the document again.

Which browsers are supported?

Modern browsers: Chrome, Firefox, Safari, and Edge (latest versions).

Is vue-office open source?

Yes. vue-office is MIT-licensed and available on GitHub.
