# YAML to TOML Converter

URL: https://phishdestroy.io/developer-tools/yaml-to-toml
Category: General dev
Where it runs: Runs locally (nothing you enter is uploaded)

Turn a simple YAML configuration made of nested mappings into TOML with [section] tables. The parser handles only a small YAML subset, so check the result.

## Example input

Nested config

```
title: Report feed
server:
  host: 127.0.0.1
  port: 8080
  tls: true
  limits:
    rps: 10
```

title = "Report feed" at the top, a [server] table with host, port and tls, and a [server.limits] table with rps = 10.

## FAQ

### Which YAML features are supported?

Indented key: value mappings at any depth with plain or quoted strings, integers, decimals, true and false; a comment line is skipped only when its # is in the first column. Everything after the first colon is taken literally, so inline comments, escape sequences, anchors, flow collections like [a, b] and multi-line | or > strings are not interpreted.

### What happens to lists and null values?

They are lost: indented - item lists are dropped from the output, lists written at the same indentation as their key become repeated keys, which is invalid TOML, and null or ~ values are skipped because TOML has no null. Convert files that contain lists with a full YAML parser instead.

### Is my configuration uploaded?

No. Parsing and conversion run in your browser and nothing is sent anywhere, so configs with host names or keys stay on your machine.
