## Description

SP REST JSON is a Chrome extension designed to enhance your experience with the SharePoint REST API. It automatically modifies the 'Accept' header in API requests to retrieve JSON responses instead of XML, providing cleaner and more accessible data formats.

The extension monitors your active tabs and changes the request headers when URLs match typical SharePoint REST API paths like '/_api/web/', '/_api/site/', and '_vti_bin/ListData.svc'. It supports both SharePoint Online and on-premises environments. Users can customize URL filters and specify the desired 'Accept' header format, including options such as 'application/json;odata=verbose', 'minimalmetadata', 'nometadata', or revert to 'text/xml'. This tool simplifies API interactions by enabling direct JSON response display in your browser, enhancing development and debugging workflows.
