INI is a simple configuration file format with sections in square brackets and key=value pairs. It is widely used by Windows applications, PHP, Python, and many other tools.

How does the conversion work?

The first CSV row is the header row; those field names become INI keys. For each subsequent row, the first column value becomes the section name, and every other column maps to a key from the header row.

What if two rows share the same first-column value?

Each row always produces its own section block. If two rows have the same section name, both blocks appear in the output — most INI parsers merge duplicate sections automatically.

Are quoted CSV fields supported?

Yes. Fields wrapped in double quotes are handled correctly, including fields that contain commas or newlines inside quotes.

Can I use a custom delimiter?

Yes. The tool supports comma, semicolon, tab, and pipe delimiters. Select the one that matches your CSV source before converting.
