What exactly does this do?

It opens your 7Z archive, reads the file stored inside, and returns it as JSON. If the archive stores a JSON document, you get that document back as a structured JSON report.

My archive has several files inside. Will this still work?

This page is for archives that hold one JSON document. For multi-file archives, unpack them first and pick the JSON file.

What if the file is not a 7Z archive?

The conversion fails with a clear error. Nothing is faked or guessed.

Convert a 7Z archive to JSON

A 7Z archive is a compressed container that can wrap one or more files. When the thing inside is a JSON document, you often want the readable JSON back. This page converts a 7Z archive to JSON.

How to convert

Upload a 7Z archive up to 40 MB whose stored content is a JSON document.
Press Convert file.
Read the decompressed JSON on the result page.

What you get

The stored JSON document, decompressed and returned as a structured JSON report. No shell tricks, no intermediate downloads — the archive member is streamed straight into the report.

When this is useful

Someone handed you a .7z and you just want the JSON payload
You want to reuse a compressed JSON document in another tool
You want to confirm what a 7Z wrapper actually contains
