Users encounter a JSON parsing error when attempting to load SharePoint pages, preventing the page content from displaying correctly.

How to Fix SharePoint Page JSON Parsing Error in Chrome

Product: SharePoint
Device & OS: not provided
Scenario: Loading or interacting with a SharePoint site page in a web browser like Google Chrome.
Observed behavior: The SharePoint page fails to load and displays a JSON parsing error message, often caused by browser extensions interfering with page content or server responses.

Before you start

Before modifying your browser settings, verify if the error occurs on all SharePoint sites or just a specific page to rule out server-side issues.

Solution 1Recommended

Test in Incognito Mode and Disable Interfering Extensions

Identify and disable extensions like JSONView that might intercept or alter JSON responses on SharePoint pages.

Browser extensions designed to format or read JSON code (such as JSONView) can intercept SharePoint's background data requests. This interception corrupts the data SharePoint expects, resulting in a parsing error.

Open an Incognito Window

Press Ctrl+Shift+N in Chrome to open an Incognito window. Navigate to the affected SharePoint page to see if it loads successfully without extensions.

Access Chrome Extensions

If the page works in Incognito, return to your normal browser window, click the three-dot menu in the top right, go to Extensions, and select Manage Extensions.

Disable JSONView

Locate the JSONView extension (or any similar developer extensions) and toggle the switch to turn it off or click Remove to uninstall it completely.

Hard Refresh the Page

Go back to the SharePoint page and press Ctrl+F5 to force a hard refresh and reload the content without the extension's interference.

Test in Incognito Mode and Disable Interfering Extensions

Alternative Fix Confirmed: Community users have confirmed that completely removing the JSONView extension permanently resolves this specific SharePoint loading error.

Solution 2

Perform a Hard Refresh to Clear Local Cache

A hard refresh can temporarily bypass cached problematic scripts that are causing the JSON parsing error.

Solution 3

Collect Error Logs for IT Support

If the error persists across multiple browsers like Firefox and Edge without extensions, gather necessary details for your IT administrator.

Frequently Asked Questions

Why do JSON formatting extensions cause errors on SharePoint?

Extensions like JSONView intercept JSON responses to format them nicely for developers. Because SharePoint heavily relies on raw JSON data for rendering page components, modifying these responses disrupts the page's ability to display correctly.

Does this JSON parsing error only happen in Google Chrome?

No. While commonly reported in Chrome, users can experience similar parsing errors in Firefox or Microsoft Edge if they have installed interfering developer extensions or have a corrupted browser cache.

What does pressing Ctrl+F5 actually do on a SharePoint page?

Pressing Ctrl+F5 forces a hard refresh in your browser. It bypasses the browser's locally cached files and downloads all the page's scripts and resources fresh from the SharePoint server, which can resolve temporary loading glitches.
