📘 About the JSON Viewer
Large JSON from an API can be hard to read. The tree view shows each object and array as a branch you can open or close, with the number of keys or items, and colours for strings, numbers, true/false and null.
Click any value to copy its path, such as $.user.roles[0], for use in code or JSONPath queries.
💡 How to use the JSON Viewer
Paste your JSON.
Click "View as tree".
Open and close branches, or click a value to copy its path.
❓ Frequently asked questions
Can it open big files?
Yes, files of a few megabytes work well. Very large files may be slow because every node is drawn in the page.
