How to use it
- Accepts an object or an array of objects. Headers are the union of all fields; missing values become empty cells.
- Nested arrays and objects are serialized as JSON inside a cell, without flattening rows.
- Formula protection adds an apostrophe to formula-like text. CSV downloads include a UTF-8 BOM for spreadsheet compatibility.

CSV cannot preserve column types. Import identifier columns explicitly as text.
Why is there an extra apostrophe?
Formula protection is enabled by default and can be disabled for trusted data.
