TOML to INI Converter Online

What is TOML to INI Conversion?

TOML to INI conversion takes a TOML config file and rewrites it in the simple key=value style INI uses. The two formats look similar at first glance: both have [section] headers and key-value pairs. But TOML supports proper types, deep nesting, and arrays, while INI is intentionally bare-bones. A toml to ini converter strips back the syntax to fit INI's simpler shape, flattening nested tables and joining arrays into comma-separated strings. INI is what older tools and a long list of desktop apps still read.

Why Convert TOML to INI?

INI files are still everywhere in legacy software: PHP's php.ini, Git's .gitconfig, MySQL's my.cnf, Python's configparser, and many older Windows apps. If you're migrating config from a TOML-based setup to one of those tools, a toml to ini conversion saves you from rewriting line by line. Use this tool when you need to migrate TOML config to a tool that reads INI, generate php.ini or my.cnf snippets from TOML drafts, share configuration with software that doesn't speak TOML, or simplify TOML settings into a format that any language can parse without a library.

How Our TOML to INI Converter Works

When you click Convert, the tool maps top-level TOML tables to INI sections (the [section] headers) and writes the keys inside each table as key=value pairs. Nested TOML tables get flattened with dot notation in the section name (so [server.tls] becomes [server.tls] in INI too, which most parsers still handle). Arrays are written as comma-separated values, the standard INI approach for lists. The conversion runs in your browser. Your TOML data never reaches a server.

Features You Get

• Section mapping: TOML tables become INI [sections] with the same names.
• Flattening: deeply nested tables become dot-separated section names so the structure survives.
• Array handling: TOML arrays become comma-separated values inside INI keys.
• Type-safe values: numbers and booleans are written without surprise quotes.
• Upload support: load a .toml file from your device or drag-and-drop it into the input.
• One-click copy: grab the INI output with the Copy button and paste it into your config file.

How to Use the Tool

1. Paste your TOML into the input panel, or use the Upload File button to load a .toml file.
2. Click the Convert button to generate the INI output.
3. Confirm the sections look right and the keys line up with what your config parser expects.
4. Click the Copy button to copy the INI to your clipboard.

Common Use Cases

• Config migration: moving config from a TOML-based tool to an INI-based one without manual rewriting.
• PHP and database configs: generating php.ini or my.cnf snippets from TOML sources.
• Desktop apps: many Windows and cross-platform tools still read INI for settings.
• Python configparser: INI is the default format for the standard library configparser module.

Example Conversion

[server]
host = "localhost"
port = 3000

[database]
user = "admin"
password = "secret"

[server]
host=localhost
port=3000

[database]
user=admin
password=secret
