Lua to JSON
Convert Lua table to JSON โ instantly in your browser, nothing uploaded.
A Lua table is the data structure Lua uses for both arrays and maps, common in game and embedded scripting, and JSON is the universal data-interchange format understood by every language and API. This free tool converts one into the other entirely inside your browser, so your data is never uploaded to any server. Paste your Lua table and the JSON appears instantly โ then copy it or download it as a file. No signup, and it works offline once loaded.
Frequently Asked Questions
How do I use this Lua table to JSON tool?
Paste your input into the box above and the result appears instantly below โ nothing to press and nothing to upload. It runs entirely in your browser, so you can copy the output or download it as a file. If the input has an error, a clear message tells you exactly what to fix.
Is it free and private?
Yes on both counts. It is completely free with no signup or limits, and it is private because everything runs locally in your browser โ your data is never sent to a server. That makes it safe for production schemas, tokens and payloads, and it keeps working offline once the page has loaded.
What is JSON?
JSON is the universal data-interchange format understood by every language and API. Converting your Lua table into JSON lets you reuse the same structure in tools that expect JSON, without rewriting it by hand.
Is there a size limit?
There is no fixed limit because nothing is uploaded โ the only constraint is your device's memory, so typical inputs process instantly. The engine loads on first use and is cached afterwards, so repeat runs start immediately.
Does it work on mobile and every browser?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install, and works offline once loaded. The result can be copied or downloaded on any device.
