IMPLEMENTATION

Viewers responsible for this format

CSV stores rows as delimited text, but quoting, encodings and inferred types still need parsing. Anyfile registers the selected file with DuckDB-Wasm and returns bounded Arrow batches to the table viewer.

Common question

Can Anyfile open a very large CSV?

It avoids rendering every row at once, but parsing and queries still use this device’s memory.
