| Comments | Supported with # | No official comment syntax |
| GitHub rendering | Shown as code block | Renders with full formatting and tables |
| Developer audience | Config authors and readers | Broad technical audience |
| Tables | Arrays of tables, not visual | Pipe-separated visual tables |

How to Convert TOML to Markdown
-
1
Upload your TOML file
Drag and drop your .toml configuration file onto the converter, or click browse to select from your device. The file is sent over an encrypted connection.

Server-side conversion
The server parses your TOML and converts it to Markdown. Table sections become Markdown headings with two-column tables. Arrays of tables produce multi-row Markdown tables.
-
3
Download the Markdown file
Save your converted .md file. The server copy is automatically deleted after processing. Paste the result directly into GitHub, GitLab, or your documentation system.
Frequently Asked Questions
TOML table sections ([section]) become Markdown level-2 headings with a two-column table of key-value pairs underneath. Arrays of tables ([[section]]) become multi-row Markdown tables.
No. TOML comments are stripped during parsing. The Markdown represents the data structure only. If you need to document meanings, edit the Markdown output after conversion.
Yes. The converter produces GitHub Flavored Markdown (GFM) with proper pipe table syntax, heading levels, and code spans that render correctly in GitHub and GitLab.
Yes. Cargo.toml is valid TOML and converts cleanly to Markdown. The [package], [dependencies], and other sections each become formatted Markdown sections with tables.
Yes. Files are uploaded over HTTPS and are deleted from the server immediately after conversion. No data is stored, logged, or shared.
Yes, completely free with no limits on file size or number of conversions. No account required.
TOML datetime values are rendered as ISO 8601 strings in the Markdown table cells. The precision (date-only, datetime, or datetime with timezone) is preserved from the TOML source.
TOML inline tables are expanded and rendered as Markdown definition lists or nested tables within their parent section, depending on depth and structure.
Yes. Nested TOML sections produce Markdown with progressively deeper heading levels (##, ###, ####) to represent the hierarchy visually.
