Can I save the filtered view?

Yes. The Save view button downloads exactly the rows currently shown, with the header row, re-quoted correctly.

Why does it stop at 100,000 rows?

To keep the tab responsive. Everything happens in browser memory, so beyond that a command-line tool or a database is the better instrument.

About this tool

Opens delimited data as a sortable, filterable table, which is a faster way to understand an unfamiliar export than reading raw text. Sorting detects whether a column is numeric, a date or text, so numbers sort as numbers rather than lexicographically.

Limitations

Rows are virtualised for display. Very large files still have to be parsed into memory first.
