TOML vs TSV: Format Comparison
Key differences between the two formats
| Feature | TOML | TSV |
|---|---|---|
| Structure | Hierarchical with [tables] and [[arrays]] | Flat rows and columns |
| Data types | Native strings, integers, floats, booleans, dates | All values are text |
| Delimiter | Equals sign for key-value pairs | Tab characters between fields |
| Nesting | Full nesting with tables and dotted keys | Not supported |
| Comments | Supported with # syntax | Not supported |
| Spreadsheet paste | Not directly pasteable | Paste directly, columns align automatically |
| File size | Moderate with section headers | Very compact, minimal overhead |
When to Convert
Common scenarios where this conversion is useful
Pasting config data into spreadsheets

Auditing Rust dependencies
Extract dependency information from Cargo.toml and convert to TSV for review in spreadsheets, version tracking, or compliance documentation.
Command-line data processing
TSV is easy to process with tools like awk, cut, and sort. Convert TOML data to TSV for shell-based data manipulation and filtering.
Database bulk loading
Many databases support TSV for COPY operations. Convert TOML configuration data to TSV for bulk insertion into PostgreSQL or MySQL.

Frequently Asked Questions
Arrays of tables ([[items]]) produce the best multi-row TSV output. Each table in the array becomes a row with consistent column headers.
Nested tables are flattened using dot notation for column headers. For example, [owner.contact] with email becomes a column named 'contact.email'.
Yes. TSV is the native clipboard format for spreadsheets. Copy the output and paste into Excel or Google Sheets for automatic column alignment.
Inline arrays become a single TSV cell containing comma-separated values. Arrays of tables are expanded into separate rows.
All values are converted to their text representation in TSV. Integers, floats, booleans, and dates appear as strings in the tab-separated output.
Comments are stripped during parsing. TSV format does not support comments.
Tab characters within TOML string values are escaped or replaced to prevent breaking the TSV column structure.
Yes. Flat key-value pairs produce a single-row TSV with keys as headers and values as the single data row.
