What is JSON to INI Converter?
JSON to INI Converter transforms configuration data between the JSON and INI formats. JSON stores hierarchical data as nested objects and arrays, while INI is a flat, human-readable format built around [section] headers and key=value pairs. This tool handles the bidirectional mapping: nested JSON objects become dotted INI sections like [db.pool], scalar values are typed (numbers, booleans, strings), and comments and quoting are respected. Everything runs in your browser with zero uploads.
Key Benefits
- Convert JSON config to INI and INI back to JSON
- Nested objects map to dotted [parent.child] sections
- Handles quoted strings, booleans, numbers, and comments
- No data leaves your browser — fully offline-capable
Common Use Cases
- •Migrating Python ConfigParser INI files to JSON config
- •Converting desktop app settings to web app config
- •Generating INI from structured JSON templates
- •Inspecting and round-tripping legacy configuration files
How to Convert JSON to INI
- Choose direction: Pick JSON to INI or INI to JSON. Click the swap button to flip the direction at any time.
- Paste your input: Type or paste your JSON object or INI text into the input box. Use the Load Example button to try sample data.
- Convert: Click the Convert button. The tool parses the input and writes the converted output to the right panel.
- Copy or clear: Click Copy to send the output to your clipboard, or Clear to reset both panels and start over.
Key Features
- Bidirectional conversion: JSON to INI and INI to JSON

Frequently Asked Questions
What is the difference between JSON and INI?
JSON is a hierarchical format that supports nested objects and arrays, while INI is a simpler flat configuration format using [section] headers and key=value pairs. This tool bridges them: JSON objects become INI sections, and INI sections become nested JSON objects.
How are nested JSON objects handled when converting to INI?
Nested objects become dotted section names. For example, a JSON object { "db": { "pool": { "size": 10 } } } produces an INI section [db.pool] with the key size = 10. Deeply nested arrays or complex values fall back to inline JSON strings, since INI has no native representation for them.
Are comments preserved during conversion?
Comments (lines starting with ; or #) are ignored when parsing INI to JSON and are not carried into the output. When converting JSON to INI, the tool does not add comments automatically, but you can add them to the output afterward.
Does this tool send my data anywhere?
No. All conversion happens entirely in your browser. Your configuration data never leaves your device, is never uploaded, and the tool works offline once the page has loaded.
