Working from a .tsv file
Tab-separated files come out of database shells, BI exports and anything that had to avoid commas inside its own values. They go through the same reader as CSV - the tab simply wins the separator sniff - so there is nothing to configure.
Reading CSV
- →Leading zeros are preserved. A column containing 01234 is kept as text, never turned into the number 1234.
- →An empty cell becomes NULL, not an empty string — the two mean different things once the data is in a database.
- →Dates are only treated as dates when the format is unambiguous. 03/04/2025 could be March 4th or April 3rd, so it stays text unless another value in the column settles it.
