What this tool does
About the YAML to CSV
This converter reads YAML input and rewrites the same usable information as CSV. It changes the representation, not the meaning of the source data, except where the target format cannot express the same structure.
It is useful when data needs to move between spreadsheets, APIs, configuration files, databases, or documentation without retyping records.
How to use it
- Paste YAML in the input pane. Use the example button if you want to see the expected syntax.
- Review the input for the structure shown in the example. Then select “Convert to CSV.”
- Inspect the result for warnings or structural differences, then copy it into the destination system.
Practical example
Start with a known input
Try this sample input: - name: Avery email: avery@example.com Select “Convert to CSV” and compare the result with the source before using it elsewhere.
What to know about the result
- CSV is designed for rows and columns. Nested values must be flattened or represented as text, and quoting is used when a cell contains a comma, quote, or line break.
- YAML uses indentation to express structure, so spacing is meaningful and tabs should not be used for indentation.
- Processing happens in this browser. Your entered text and selected files are not sent to FormatCalc for conversion.
