What YAML structure does this tool expect?

The tool expects a top-level YAML sequence (array) of mappings (objects). Each item should be a key-value map, for example: "- name: Alice\n age: 30". Scalar arrays (lists of plain strings or numbers) are not supported.

Are missing keys handled correctly?

Yes. If some records are missing certain keys, those cells are left empty in the TSV. The header row always includes every key found across all records.

Is my data sent to a server?

No. All parsing and conversion happens locally in your browser using js-yaml. Nothing is uploaded or stored.

Why use TSV instead of CSV?

TSV uses a tab character as the delimiter, which almost never appears in data. This avoids the quoting complexity that CSV requires for values containing commas. Most spreadsheet apps import TSV as easily as CSV.

What happens with nested objects or arrays?

Nested values are serialized to a compact JSON string inside the TSV cell so no data is lost. Simplify your YAML structure first if you need a fully flat result.

Can I choose which columns to include?

Yes. After parsing, each column header has a checkbox so you can include or exclude individual columns before copying or downloading.
