CSV to YAML Converter

This tool converts comma-separated values (CSV) into clean, structured YAML instantly. It’s ideal for developers, content editors, or data analysts who need to turn spreadsheet-style rows and columns into a readable, key-value format. You can paste or upload CSV, tweak formatting options, and export the YAML result on the spot.

Paste your input above or import a file below.

How to Use:

Paste your CSV data into the input box on the left. You can also upload a .csv or .txt file using the Choose File button. Then configure the behavior using the Options panel:

  • First row is header: When enabled, the first row will be used as field names for each YAML object.
  • Trim values: Removes extra spaces around each field value before conversion.

As soon as you import or edit your input, the YAML output appears on the right. You can copy the result using Copy Output, or save it using Export to File. Use Clear All to reset both input and output.

What the CSV to YAML Converter Tool does:

It reads each row from your CSV input and converts it into either YAML objects (if headers are enabled) or YAML arrays. Each comma in your CSV becomes a structured line in YAML, preserving the column-to-key relationship. The output is formatted with proper indentation and optionally trimmed for whitespace.

Example:

Input CSV:

name,age,city
Alice,28,Paris
Bob,34,Berlin

Output YAML:

  name: Alice
  age: '28'
  city: Paris
- name: Bob
  age: '34'
  city: Berlin

Common Use Cases:

Use this tool when you need to prepare config files, API mock data, or human-readable data from spreadsheets. It’s especially useful for transforming table-based content into YAML for frontend apps, static site generators, testing suites, or serverless tools. Just paste, preview, and export no coding required.

Useful Tools & Suggestions:

If you’re going back to flat formats, YAML to CSV Converter flips your structured data into rows and columns again perfect for spreadsheets or table-based tools. And if you’re jumping between structures, CSV to JSON Converter gives you another machine-friendly format that plays well with modern apps and services.
