TSV (Tab-Separated Values) is a plain-text format where each record is a line and fields within each record are separated by tab characters. It is commonly used for data exports from spreadsheets and databases.

INI is a simple configuration file format that uses sections in square brackets and key=value pairs. It is widely used by Windows applications, PHP (php.ini), Python (configparser), and many other tools.

How does the conversion work?

The first TSV 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 with its corresponding value.

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.

What happens with empty cells in the TSV?

Empty cells produce key= entries with an empty value, which is valid INI syntax. Section names that are empty get an auto-generated name like section_2 to keep the output parseable.

Summary

Paste tab-separated data and convert it to INI format, with first-column values as section names and header fields as keys.

How it works

Paste or type your TSV data into the input box.
The first row is treated as the header and its fields become the INI key names.
The first column value in each subsequent row becomes the INI section name.
All remaining columns become key=value pairs inside that section.
Click "Convert" to generate the INI output.
Copy the result or download it as a .ini file.

Use cases

Convert spreadsheet exports saved as TSV into INI configuration files.
Transform tab-delimited database exports into application config files.
Migrate settings stored in TSV format to INI-based applications.
Quickly generate INI sections from structured tabular data.
Batch create configuration files from TSV exports for testing environments.
