How it works

Three steps, no account

Paste or drop your CSV

Comma-separated values with a header row works best. You can also upload a .csv file directly.

Review the table

Transpose it, delete blank rows, or remove duplicates before you generate output.

Pick a format and generate

Choose from 28 output formats, then copy the result or download it as a file.

FAQ

Common questions

Is my data uploaded anywhere?

No. Parsing, editing, and generating output all run in your browser using JavaScript — the CSV you paste or upload never touches a server.

How large a file can I convert?

There's no server-side limit because there's no server involved — your browser's own memory is the ceiling.

What happens if a row has the wrong number of columns?

The parser expects every row to have the same number of comma-separated values as the header row and flags "Invalid CSV format" if one doesn't — fix the mismatched row and it'll re-parse as you type.

Can I edit the data before converting?

Yes — the table below the input lets you transpose rows and columns, delete blank rows, or remove duplicate rows before you generate the final output.

How to Convert CSV to TOML Online?

Transform your CSV data into a TOML (Tom's Obvious, Minimal Language) configuration file using our online converter. TOML is a popular configuration file format known for its readability and ease of use.

1. Upload or Paste Your CSV Data

Upload your CSV file or paste your CSV data into the provided input area. The converter will automatically detect the delimiter (usually a comma) used in your CSV file.

2. Configure the TOML Structure (Optional)

Depending on the converter's capabilities, you may be able to customize the generated TOML:

Table Names: Specify how the TOML tables (sections) will be named. You might use the first column as the table name, create a single table, or use a custom naming scheme.
Key Names: The converter will likely use the column headers as keys in the TOML. You might be able to customize how these keys are named (e.g., converting to snake_case or camelCase).
Data Types: The converter will attempt to infer the data types (string, number, boolean, date), but you might need options for handling specific cases.

3. Generate and Preview the TOML

The converter will generate the TOML representation of your CSV data. A preview area will allow you to review the TOML before downloading or copying.

4. Download or Copy the TOML Data

The generated TOML data can be downloaded as a .toml file or copied to your clipboard for pasting into your configuration files or applications.

What is CSV?

CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. Each line of the file is a data record, with each field separated by commas.

What is TOML?

TOML (Tom's Obvious, Minimal Language) is a configuration file format that's easy to read due to its simple syntax. It's designed to be minimal, human-readable, and easily parsed by machines. A simple example:

name = "Example App"
version = "1.0"

[owner]
name = "Alice"
dob = "1985-01-10T14:30:00Z"

[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
enabled = true

This converter will transform your tabular CSV data into a TOML structure, making it suitable for use in applications or systems that utilize TOML for configuration. The specific TOML structure will depend on your chosen settings.
