Bidirectional CSV and YAML converter. Convert CSV spreadsheet data to YAML configuration format and parse YAML back to CSV.
Format Converter
About This Tool
The CSV YAML Converter is a bidirectional tool that converts between CSV spreadsheet data and YAML configuration format. CSV to YAML mode parses CSV rows into structured YAML with automatic type detection for numbers, booleans, and null values. YAML to CSV mode parses YAML arrays back into tabular format with flattened keys for nested objects.
Key Features

Frequently Asked Questions
What is the CSV YAML Converter?
The CSV YAML Converter is an online bidirectional converter that allows you to convert CSV spreadsheet data to YAML configuration format and parse YAML back to CSV. It runs entirely in your browser with no data sent to any server.
How does CSV to YAML conversion work?
The first row of your CSV is used as YAML key names. Each subsequent row becomes a YAML object with automatic type detection for numbers, booleans, and null values.
How are nested YAML objects converted to CSV?
Nested YAML objects are flattened using dot notation for keys. For example, a nested key like server.port becomes a column header 'server.port' in the CSV output. This preserves the hierarchical structure in a flat tabular format.
Does the converter support automatic type detection?
Yes. When converting CSV to YAML, the tool automatically detects and converts numeric values, boolean values (true/false), and null values to their proper YAML types. Strings that look like numbers remain as strings if they are quoted in the CSV.
What CSV delimiters are supported?
The converter supports comma, semicolon, tab, and pipe delimiters. You can select the appropriate delimiter for your data format, and the tool handles quoted fields and escaped characters correctly.
