INI to JSON

System ideaMissing a tool?

Convert INI config files into JSON locally

Paste INI text with `[section]` headers, `key=value` pairs and `;` or `#` comments to convert it into a JSON object. Runs entirely in your browser.

JSON
{
  "server": {
    "host": "localhost",
    "port": "8080"
  },
  "database": {
    "name": "app_db",
    "user": "admin"
  }
}

Everything on this page is processed in your browser. Nothing is uploaded.

What this tool does

INI is a simple config format used by many desktop apps, build tools and legacy services: keys before any section header become top-level values, and each `[section]` groups the keys that follow it until the next header. This tool parses that structure, skips full-line comments starting with `;` or `#`, and strips a single layer of matching quotes from a value, producing a JSON object with one property per section (plus any global keys) so the config can be read by JavaScript or fed into a JSON-based tool.

How to use it

  1. Paste INI text, or load the example.
  2. Review the parsed JSON, or the error if a line couldn't be read.
  3. Copy the JSON result.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

Is my INI file uploaded anywhere?
No. Parsing happens in JavaScript running in the page, so nothing you paste ever leaves your device.
What happens to keys before the first section?
They become top-level properties of the JSON object, alongside one property per section, matching how most INI readers treat global keys.
Are values converted to numbers or booleans?
No, every value stays a string, since INI has no native type system; convert specific fields afterwards if your use case needs numbers or booleans.
