json-pretty-toml

Convert JSON to flat TOML with max 2-level keys.

Installation

npm install -g json-pretty-toml

Or use with npx (no installation):

npx json-pretty-toml < input.json

Usage

json-pretty-toml < input.json > output.toml

Rules

• First level → [Table]
• Second level primitive → key = value
• Second level object → key.sub = { ... }

Example

Input:

{
  "gateway": {
    "port": 18789,
    "auth": { "mode": "token" }
  }
}

Output:

[gateway]
port = 18789
auth.mode = "token"
