Working with JSON shouldn’t be hard. This simple tool on Dailiyo.xyz helps you paste, validate, format, sort, and download JSON in seconds—right in your browser. No sign-up, no uploads, no data leaving your device.
What this tool does
- Validate JSON: Quickly check if your JSON is valid. If there’s an error, you’ll see a helpful message so you can fix it fast.
- Pretty Print (Format): Turn messy JSON into clean, readable output with your choice of 2 spaces, 4 spaces, or tabs.
- Minify: Need a compact version for production or network transfer? Toggle Minify to remove all whitespace.
- Sort Keys: Make your objects stable and easier to diff by alphabetically sorting keys at every level.
- Upload & Download: Open a
.json
file to edit, then download clean JSON with one click. - Copy Output: Copy the result directly to your clipboard for use in code, config files, or API requests.
Why it’s useful
Whether you’re building an app, testing an API, or sharing data with teammates, clean JSON saves time. Pretty JSON helps you spot mistakes, and minified JSON keeps payloads lightweight. Sorting keys gives consistent results across commits and pull requests, which makes code reviews easier.
How to use
- Paste your JSON into the left box (or click Upload JSON).
- Click Validate to check for errors.
- Click Format to pretty print, or enable Minify for compact output.
- Turn on Sort keys if you want alphabetical order for all object keys.
- Copy or Download the final JSON when you’re done.
Privacy & performance
This tool runs 100% in your browser using JavaScript. Your JSON never leaves your computer, so it’s fast and private—ideal for sensitive configs, tokens (don’t share them!), or internal data while you debug.
Common use cases
- Cleaning up API responses from Postman or cURL
- Preparing config files like
package.json
,tsconfig.json
, or app settings - Minifying JSON for CDN or production builds
- Sorting keys to reduce noisy diffs in Git PRs
- Quick sanity checks when editing by hand
Tips
- If you see an error, double-check quotes, commas, and brackets. JSON requires double quotes for keys and strings.
- Use Minify before downloading to keep files small in production.
- Keep Sort keys on for predictable output when reviewing changes.
