What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

About Format JSON.

Format, Validate, and Minify JSON in Your Browser

Paste JSON, JSONC (with comments), or JSON5 and CipherForces pretty-prints it with configurable indentation (2, 4, or tab). Invalid JSON? We show the exact line and character of the first error. Works with multi-megabyte inputs — large files run through a Web Worker so the UI never freezes.

Common Use Cases

API debugging: Paste a minified API response and make it readable instantly.
Config file review: Format a tangled config file before committing to Git.
JSONC / JSON5 conversion: Strip comments and trailing commas to produce standard JSON.
Size optimization: Minify JSON for bundle size before production deploys.

Key Features

Error highlighting: Exact line and character of the first syntax error.
Tree view: Collapsible object/array explorer with path-to-clipboard.
Web Worker processing: Large inputs (1 MB+) don't freeze the UI.
JSONC + trailing comma tolerance: Comments and trailing commas are detected and stripped gracefully.

Privacy: All parsing is client-side. Your JSON (even with API keys) never leaves your device.

FAQ

Frequently asked questions.

How do I format messy JSON online for free?

Paste your JSON into the CipherForces JSON Formatter and it instantly indents and beautifies the structure. There is no signup and nothing to install. Copy the formatted result back out when you are done. The tool is completely free and works directly in your browser.

Is my JSON uploaded to a server when I format it?

No. The JSON Formatter runs entirely in your browser using JavaScript, so your data never leaves your device or gets sent to any server. This means you can safely format sensitive payloads, API responses, or config files without privacy concerns or third-party access.

Can the JSON Formatter check if my JSON is valid?

Yes. When you paste JSON, the formatter parses it and reports an error if the syntax is broken, such as a missing comma or unclosed bracket. Valid JSON gets cleanly indented, so the tool doubles as a quick way to confirm your structure is correct.

Does the JSON Formatter work offline once the page loads?

Yes. Because all formatting happens client-side in your browser, the tool keeps working after the page has loaded even if your connection drops. No round trip to a server is needed to indent or validate your JSON, so results appear immediately every time.
