How to Use:

  • Paste your YAML into the input box or upload a .yaml, .yml, or .txt file
  • The tool parses your YAML and turns it into TSV (tab-separated values) format
  • Toggle Flatten nested values to convert nested keys like location.city into a flat row
  • The first line of output contains column headers (keys), and the second line holds the values
  • Output updates live as you type or load a file
  • Click Convert to manually re-run the conversion
  • Use Copy Output to copy the TSV result to your clipboard
  • Click Export to File to download the output as a .tsv file
  • Toggle Maximize output to expand the output display for large data
  • Click Clear All to reset input, output, file name, and all toggles

What Transform YAML into TSV can do:

This tool takes any valid YAML object and converts it to a single TSV row. It flattens nested keys (like user.name) into dot notation if flattening is enabled, making the output simple and spreadsheet-friendly. If the YAML contains lists, it joins them into comma-separated values within the TSV. It’s useful for exporting YAML data into tabular formats, especially when working with tools like Excel, Google Sheets, or command-line processing systems. The tool runs entirely in your browser, keeping your data secure and private.

Example:

YAML Input:

name: Alice
age: 30
skills:
  - Python
  - YAML

TSV Output:

name	age	skills
Alice	30	Python, YAML

Common Use Cases:

Use this when preparing YAML data for import into spreadsheet tools, flattening configs for audits, converting structured logs into rows, or transforming API test data into analysis-friendly formats. It’s also useful for converting YAML into plain-text formats compatible with TSV parsers.

Useful Tools & Suggestions:

Once you’ve transformed YAML into TSV, consider using Trim TSV Columns to clean up any messy edges. And if the data still feels bulky, Display TSV Statistics gives you a quick snapshot of how much you’re working with.
