Usage notes

Quoted commas and embedded newlines are parsed as cell content. All rows must have the same number of columns.

Input limits are 5 MiB, 5,000 data rows, 50 columns and 100,000 cells.

Formula escaping prefixes cells that spreadsheets could execute with an apostrophe. Disable it when you need to preserve literal formula text.
