Good to know
Requires a non-empty, unique header for every column and a consistent number of cells in each row.
Every cell stays a string: leading zeros, long IDs and date-like values are preserved. No automatic type guessing.
Text files up to 5 MB are supported. Downloads are encoded as UTF-8.

Questions
Why are numbers exported as strings?
To keep leading zeros, postal codes and long IDs exactly as they are. Convert types in your own code if needed.
What causes a header error?
Every column needs a unique, non-empty name because it becomes a JSON key.
