Not sure if this is just me but debugging API responses with multiple timestamp fields has always been annoying.

You see 1714000000 in a JSON payload and have to:

1. Open new tab
2. Search epoch converter
3. Paste the value
4. Note the date
5. Go back
6. Do it again for last_login, updated_at, expires_at...

I finally got fed up and built JSON Epoch Converter — you paste your raw JSON and it replaces every epoch field with a human-readable date in one click.

The thing I couldn't find in existing tools was support for mixed precisions in the same payload. Real-world JSON often has one field in seconds and another in milliseconds. Most converters assume one or the other. This auto-detects each field independently.
