Solution 1Recommended

Use Private Browsing and Clear Browser Cache

Using an InPrivate or Incognito window temporarily disables extensions and uses a fresh cache, helping to quickly identify if outdated browser data is causing the gibberish text.

Browser cache issues or conflicting third-party extensions often disrupt how web pages, including Office Online viewers, decode and render text.

1
Update Your Browser

Ensure Microsoft Edge or Google Chrome is updated to the latest version by clicking the three-dot menu in the top right, navigating to 'Help' or 'Settings', and selecting 'About'.

2
Open an InPrivate or Incognito Window

Press Ctrl+Shift+N (for Chrome) or Ctrl+Shift+N (for Edge) to launch a private window. Log into your OneDrive account and attempt to open the Excel file.

3
Clear Browser Cache

If the file displays correctly in the private window, return to your normal browser, press Ctrl+Shift+Del, check 'Cached images and files', and click 'Clear data'.

4
Disable Extensions

If the problem continues, access the extensions menu via the puzzle piece icon or browser settings, and toggle off third-party add-ons one by one to isolate the conflict.

Use Private Browsing and Clear Browser Cache
Verify File Integrity: If the file still displays gibberish in private mode across multiple browsers, test opening it on the computer where it previously worked to ensure the cloud file itself hasn't become corrupted.

Frequently Asked Questions

Why do Excel files show as gibberish in my web browser?

This typically occurs due to corrupted browser cache, outdated browser versions, or conflicting browser extensions that interfere with the web page's text encoding.

Does this mean my OneDrive Excel file is corrupted?

Not necessarily. If the file opens correctly on another computer or correctly renders in an Incognito window, the file itself is safe and the issue is strictly localized to your browser.

How do I fix encoding issues in Microsoft Edge or Chrome?

Modern browsers automatically detect text encoding. If it fails on OneDrive, resetting the browser settings to default or clearing the cache usually forces the browser to re-detect and resolve the encoding issue.

Can I prevent browser gibberish by opening the file in a desktop app?

Yes, downloading the file from OneDrive and opening it in a dedicated desktop application like WPS Office completely bypasses web browser rendering issues.
