Does this support multi-level nested sections?

Standard INI files have only one level of sections. This tool maps each [section] to a top-level YAML key with its key-value pairs nested one level deep, which is the conventional conversion approach.

Are comments preserved in the output?

INI comments (lines starting with ; or #) are stripped from the YAML output because YAML comment placement differs and would produce misleading results. You can re-add comments manually in the output.

How are boolean and numeric values handled?

Values that are purely numeric are emitted as YAML numbers. Values of true, false, yes, no, on, off (case-insensitive) are converted to YAML booleans. All other values are emitted as unquoted strings unless they contain special characters, in which case they are quoted.

What happens to keys that are not inside any section?

Top-level key-value pairs that appear before any section header are placed at the root of the YAML document, not nested under any key.

Is my data sent to a server?

No. All conversion happens entirely in your browser using JavaScript. Nothing is transmitted to any server.

Summary

Paste your INI config and instantly get clean, properly indented YAML output.

How it works

Paste your INI file content into the input panel on the left.
The converter parses each line — detecting sections, key-value pairs, and comments.
Sections become top-level YAML keys with their child keys nested underneath.
Values are automatically typed: numbers stay numeric, booleans convert to true/false, and strings are quoted only when necessary.
The formatted YAML appears instantly in the output panel on the right.
Click "Copy YAML" to copy the result to your clipboard.

Use cases

Migrate legacy PHP or Windows application configs to modern YAML-based tools.
Convert .ini settings files for use in Docker Compose or Kubernetes ConfigMaps.
Transform database or server INI configs for Ansible playbooks.
Quickly reformat configuration files when switching frameworks.
Validate and inspect INI file structure in a more readable YAML view.
Use as a learning tool to understand the relationship between INI and YAML formats.
