JSON to INI

Convert JSON into INI config. Top-level scalar keys become bare lines; top-level objects become [sections] with dot-flattened keys inside. Pairs nicely with config loaders like Python's configparser.

Example

JSON in, INI out

See exactly how JSON maps onto INI — the converter on this page produces output identical to the example below.

JSON input

{
  "app": { "name": "myapp", "debug": true, "version": "1.2.3" },
  "database": { "host": "localhost", "port": 5432, "ssl": false }
}

INI output

[app]
name=myapp
debug=true
version=1.2.3

[database]
host=localhost
port=5432
ssl=false

Use cases

What you'll use this for

Converting JSON to INI is a daily task in API integration, config management, and data pipelines.

API integration

Generate INI configs from JSON returned by config services.

Config migration

Move modern JSON config into legacy INI-consuming tools.

Data import

Feed initialization files to setup scripts and Python apps.

CI pipelines

Script INI generation as part of release builds.

Step by step

How to convert JSON to INI

Paste your JSON

Drop it into the left editor. The sample is loaded by default — clear it or click the wand to reload.

Click Convert

Or leave auto-convert on for live updates. Conversion runs entirely in your browser — no upload.

Copy or download

Copy to clipboard or save the output as config.ini.

Reverse if needed

Jump to the INI to JSON converter for a round-trip check.

FAQ

Frequently asked questions

Does it preserve types?

INI is text-only. Numbers and booleans are stringified — your loader handles parsing back.

How are nested objects handled?

Top-level objects become [section] headers. Deeper nesting is dot-flattened inside the section.

Is it free?

Yes. No signup, no limits.

What if my input is malformed?

You'll see a clear parse error in the output panel.

Need the reverse?

Use the INI to JSON converter for the opposite direction.

About

About JSON and INI

INI is a simple key=value format with optional [section] headers — long-popular for Windows software and still common in Python (configparser), PHP (php.ini), and many CLI tools.

Common pitfalls

INI has no formal spec — dialects differ on comments, quoting, and lists.
Arrays aren't natively supported; they're serialized as JSON strings.
Deeply nested JSON flattens to dotted keys inside each section.
Use configparser or ini (npm) for parsing back.
