About Bracely: Everything Everywhere All at JSON
Bracely is a JSON toolkit that opens in its own browser tab. Paste or drop in some JSON, then pick a tool from the menu on the left. Everything runs on your computer, so your data never leaves your browser.
What you can do with it:
• Make messy JSON readable: format it, sort its keys, or fix common mistakes such as trailing commas and missing quotes.
• Explore large files in a collapsible tree, a sortable table or a visual graph.
• Pull out exactly the data you need with a query, or search with typo tolerance.
• See what changed between two versions with a side-by-side diff.
• Convert JSON to other formats, such as YAML and CSV, and back again.
• Generate a schema, sample data or typed code from an example.
• Decode tokens and encoded text, and mask personal details before you share data.
Open Bracely from the toolbar button, with Alt+Shift+J, or by selecting JSON on any web page and choosing "Open selection in Bracely" from the right-click menu.
Private by design: Bracely has no server, no account and no tracking. It doesn't read or change the web pages you visit.
Bracely is also available as a website at https://bracely.saurabhpagrut.in
