How to use
Use the first row as column names, choose the delimiter and open the table. Edit cells, column order, exported columns and row filters, then apply the table to output.
A newline inside a quoted field belongs to that cell. Do not count records merely by visible text lines; compare leading zeros and quoted content too. Spreadsheet type inference requires a separate check.
