Validate, format or minify JSON with clear syntax errors.

We use reasonable safeguards to help protect your files and information while you use the service.

What to select

Paste JSON, then choose an indentation level to validate, format or minify it.

Up to 1,000,000 characters. Processing stays in this browser.

Supported formats

Plain text, JSON, XML, standard or URL-safe Base64, URL components, UUID v4, SHA-256, SHA-384, SHA-512 and CRC32.

Limits and safety

Text input is limited to 1,000,000 characters per task, and UUID generation is limited to 100 values at a time.

Frequently asked questions

Is my input uploaded or saved?

No. These developer utilities process input only in this browser tab.

Can a generated hash be reversed?

No. Cryptographic hashes are one-way values. CRC32 is a checksum for detecting accidental changes, not a security hash.
