Frequently asked questions
Why was an apostrophe added to a cell?
Formula-like strings are prefixed with an apostrophe to reduce spreadsheet formula injection risk. This intentionally changes those exported values.
Can nested objects or arrays become CSV columns automatically?
No. Flatten nested values first. Missing fields and null values export as empty cells.
