01 · How conversion works
From nested tree to flat table.
CSV has no notion of nesting, so every leaf value gets a column named by its full path. An array of objects becomes one row per element, with the union of all paths as the header row.
Values that contain commas, quotes or newlines are escaped so the file opens correctly in any spreadsheet application.
02 · Capabilities

Dot-notation columns

RFC 4180 escaping

03 · FAQ
Quick answers.
How are nested objects handled?+
Nested keys are flattened into dot-notation columns, so { user: { id: 1 } } becomes a column named user.id.
What input shape works best?+
An array of objects maps cleanly to rows. A single object produces one row with the same flattening rules.
Are commas and quotes escaped?+
Yes. Values containing commas, quotes or newlines are wrapped in quotes and internal quotes are doubled, per RFC 4180.
