Why it matters
Translates MongoDB find and aggregate pipelines into SQL and back, with unsupported stages listed.
Parses relaxed JSON (shell syntax: unquoted keys, ObjectId(), ISODate()); maps $match/$project/$group/$sort/$limit/$lookup/$unwind to SQL; reverse direction for SELECT/WHERE/GROUP BY/ORDER/LIMIT. Unsupported operators listed rather than guessed. Everything runs in your browser; nothing you paste is sent unless you press Fetch.
How to use it
- Paste or type the input the tool asks for.
- Read the summary and the table or preview.

- Copy or download the output. Nothing leaves this page.
FAQ
Is my input uploaded?
No. The work runs in your browser and nothing you type, paste or upload is sent anywhere.
Will this change my site for me?
No. It shows results and, where it writes rules or files, you copy them and apply them yourself.
Can I rely on this as official guidance?
It follows public documentation and well-known algorithms, and tells you where it is a subset or a simulation. Confirm critical changes in the official tool or a staging environment.
