JSON Formatter vs JSONLint

Both tools format and validate JSON, but they differ in how they report errors, handle large payloads, and treat the data you paste.

When JSONLint is useful

JSONLint has been around since 2010 and is familiar to many developers. It's fine for non-sensitive data where you just want a quick validity check.

When to choose Irreva

Any time the JSON contains API keys, tokens, user data, or internal service responses — paste into a client-side validator. Irreva uses native JSON.parse in the browser; the content never leaves your tab.

Frequently Asked Questions

Does JSONLint store pasted JSON?

JSONLint sends JSON to their server for validation. Their privacy policy governs what is retained.

Can Irreva format very large JSON files?

Up to several MB works well. Very large files (50MB+) may be slow depending on your device's RAM.
