Convert REPLIT to JSON

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 25, 2026
QUICK ANSWER
Is it possible to convert REPLIT to JSON?
Yes - REPLIT converts to JSON.

The .replit file is just TOML, so any TOML-to-JSON tool reproduces it as .json. The quickest route is the Taplo CLI (taplo get -f .replit -o json) or a short Python script with the built-in tomllib module; both preserve every key and value.

Why convert REPLIT to JSON?

Developers convert .replit to .JSON to feed the run command, ports, and package settings into scripts and tooling that expect JSON rather than TOML. Because TOML and JSON share the same data model of tables, arrays, strings, and numbers, the conversion is lossless for the settings themselves.

How to convert REPLIT to JSON

Taplo CLI

Install Taplo, then run taplo get -f .replit -o json > replit.json to emit the whole file as JSON. Taplo is the same TOML engine Replit uses for editing.

yj

With yj installed, run yj -tj < .replit > replit.json to convert TOML to JSON while preserving key order.

Python tomllib + json

On Python 3.11+ run python -c "import tomllib,json;print(json.dumps(tomllib.load(open('.replit','rb'))))" > replit.json to parse the TOML and dump JSON.

Quality & what to watch

  • TOML comments and formatting are dropped, since JSON has no comment support.
  • TOML's native dates become plain strings in JSON.
  • The JSON is only a data copy - Replit still reads the original .replit TOML to run your app.

Frequently asked questions

Is the .replit file really TOML?
Yes. It uses the TOML configuration format for run commands, ports, and packager settings.
Will converting to JSON lose any settings?
No settings are lost, but comments and TOML-specific date types do not carry over.
Do I need to install anything?
Either install Taplo or yj, or use Python 3.11+ which ships tomllib built in.
Can Replit run from the JSON version?
No. Replit reads the .replit TOML file; the JSON is only for your own tooling.
