TOML to JSON

A TOML to JSON Converter is a tool that transforms data from TOML (Tom's Obvious, Minimal Language) format to JSON (JavaScript Object Notation) format. This is useful because TOML is often used for configuration files, while JSON is widely used for APIs and web services.

Our TOML to JSON converter parses the TOML input you provide, understands its structure and data types, and then reconstructs it into the equivalent JSON format. You can typically paste your TOML data directly or upload a TOML file.

You might need to convert TOML to JSON when you need to integrate systems that use different data formats. For example, a configuration written in TOML might need to be consumed by an application that expects JSON. JSON is also more universally supported in web development.

Using the converter is simple: 1. Paste your TOML data into the input field or upload your .toml file. 2. Click the 'Convert' button. 3. The tool will display the converted JSON output, which you can then copy.

While our tool is designed to handle most common use cases, extremely large TOML files might face browser performance limitations. For very large files, consider a command-line tool. However, for typical configuration files, it should work perfectly.

Yes, our TOML to JSON converter typically processes data client-side. This means your TOML data is not sent to our servers, ensuring your information remains private and secure within your browser.

TOML stands for Tom's Obvious, Minimal Language. It is a configuration file format designed to be easy to read due to its simple semantics. TOML files are plain text and usually have a .toml extension.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. It is widely used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page).

This specific tool is designed for TOML to JSON conversion. We may offer a separate JSON to TOML converter for the reverse operation. Please check our list of available tools.

TOML allows comments (lines starting with #). A good TOML to JSON converter will ignore these comments during the conversion process, as JSON does not have a standard way to represent comments.

Common use cases include: converting project configurations (e.g., from Hugo or Cargo projects) for use in JavaScript applications, preparing TOML data for APIs that accept JSON, and migrating data between systems that use different formats.

Both TOML and JSON support similar basic data types like strings, numbers, booleans, arrays, and objects/tables. However, TOML has specific types like dates and times that are typically converted to string representations in JSON according to ISO 8601 format.

If your TOML input contains syntax errors, the converter will likely display an error message indicating that the input is invalid. You will need to correct the TOML syntax before a successful conversion can occur.

Many online converters, including potentially this one, offer a 'pretty print' option for the JSON output. This formats the JSON with indentation and line breaks, making it easier to read.

Neither is universally 'better'; they serve different primary purposes. TOML excels as a human-readable configuration file format. JSON is excellent for data interchange between machines due to its widespread support and simplicity for parsing. The choice depends on the specific use case.

TOML is used by various applications and projects, including the Rust package manager Cargo, the static site generator Hugo, and the Python packaging tool Poetry for their configuration files.

TOML uses tables (e.g., `[table]`) and inline tables (e.g., `key = { subkey = 'value' }`) for nesting, which are analogous to JSON objects. Arrays in TOML are similar to JSON arrays. The converter maps these structures accordingly.

JSON object key order is not guaranteed by the JSON specification, although many modern JavaScript engines maintain insertion order. TOML parsers might preserve key order, but this is not strictly enforced upon conversion to JSON. If order is critical, consider using arrays of key-value pairs.

Yes, a robust TOML to JSON converter should be able to handle all valid TOML features, including arrays of tables (e.g., `[[array_of_tables]]`), converting them into the corresponding JSON array of objects structure.

Parsing performance can vary. Generally, JSON parsers are highly optimized due to their widespread use. TOML parsing is also efficient. For most configuration file scenarios, the performance difference is negligible. The choice is usually based on readability and use case rather than raw parsing speed.
