Convert TOML to CSV online
Use this TOML to CSV converter to turn TOML files into CSV right in your browser — ideal for importing and exporting data, simple tables and moving data between apps.
When should you convert TOML to CSV?
- When you need it for importing and exporting data
- When you need it for simple tables
- To open your files in apps that prefer CSV
- To share CSV files more easily
What happens to your file
The TOML is parsed, and its nested keys and arrays are flattened into a readable shape before being written as CSV. You get the data as something a person can read, not a re-serialisation.
Settings this conversion runs with
| Input | TOML parsed and validated |
|---|---|
| Nested data | Flattened into rows or indented blocks |
| Output | CSV |
What changes
- Deeply nested structures do not map cleanly onto a flat format. Arrays of objects convert well; a tree ten levels deep will need choices made for it.
- A malformed TOML file stops the job with a parse error rather than producing a half-converted document.
