## Overview

The TOML-YAML Converter is a streamlined utility designed to transform configuration data between TOML and YAML formats, ensuring your settings remain structured and compatible across different development environments.

## Inputs

- **Conversion Direction** (select)
- **YAML Indent Size** (number): Enter YAML indent size (1-8)

## When to use

- When migrating configuration files between applications that require different data serialization formats.
- When you need to quickly validate or reformat complex nested data structures for better readability.
- When standardizing project settings to match specific framework requirements that prefer either TOML or YAML.

## How it works

- Paste your source TOML or YAML code into the input area.
- Select your desired conversion direction from the dropdown menu.
- Adjust the YAML indent size if necessary to match your project's style guide.
- Click convert to generate the transformed configuration output instantly.

## Use cases

- Standardizing configuration files for cross-platform software deployment.
- Converting TOML-based Rust project configurations into YAML for CI/CD pipeline compatibility.
- Refactoring legacy configuration files to modern YAML standards for easier maintenance.

## Frequently asked questions

### Is my data stored on your servers?

No, all conversions are processed locally in your browser to ensure your configuration data remains private.

### Can this tool handle deeply nested structures?

Yes, the converter is designed to parse and transform complex, multi-level nested data structures accurately.

### What is the purpose of the YAML indent size option?

It allows you to control the spacing of the output YAML, ensuring it aligns with your specific code formatting standards.

### Does this tool support comments in the input files?

The tool focuses on the data structure; while it processes the configuration, it is best to use it for clean data files.

### Is there a limit to the amount of text I can convert?

The tool can handle standard configuration file sizes efficiently; for extremely large files, ensure your browser has sufficient memory.
