How do I convert JSONL to TOML with this tool?

Step-by-step: 1. Paste your JSONL data (one JSON object per line) or upload a .jsonl file. 2. Choose conversion options like handling null values (skip or replace with empty string). 3. Click Convert. The tool parses each line, maps JSON keys to TOML keys, and outputs a .toml file. You can then download it or copy the result. For files with multiple lines, the tool combines them into a single TOML document using arrays of tables if the structures are identical.

Why convert from JSONL to TOML?

JSONL is ideal for streaming data, logs, or datasets where each line is a JSON record. TOML is a configuration format that's human-readable and supports comments. Converting JSONL to TOML is useful when you need to turn data logs into application config files, or when you want to manually inspect or edit the structure in a more readable way. TOML also enforces a specific schema, which can help validate the data.

How does the conversion handle nested objects, null values, and data types?

Nested JSON objects are converted to nested TOML tables. Arrays of objects become arrays of tables. Primitive types (strings, numbers, booleans) are preserved as their TOML equivalents. Since TOML has no native null type, null values are either skipped or converted to empty strings (configurable). Keys with characters not allowed in TOML bare keys are quoted. Date/time strings are left as strings unless they match TOML's RFC 3339, in which case they can be optionally converted to datetime types.
