What Count TSV Columns can do:

Count TSV Columns gives you an instant readout of how many columns each row has in your tab-separated dataset. It’s useful when you need to quickly spot rows with missing or extra fields especially when working with exported spreadsheets, logs, or malformed TSVs.

You get full control over whether to trim whitespace and ignore empty rows, plus live updates as you edit. This makes it handy for debugging or cleaning up TSVs before importing them elsewhere. No scripting or spreadsheets required just paste, count, and go.

Example:

Input:

name	age	location
Alice	30	NY
Bob	25
Charlie		LA

Options Enabled:

  • Trim cell whitespace: ON
  • Ignore empty rows: OFF

Output:

Row 1: 3 columns
Row 2: 3 columns
Row 3: 2 columns
Row 4: 3 columns

Common Use Cases:

Use this to troubleshoot TSV files with inconsistent columns, clean up data before importing to a database, or verify that every row meets schema expectations. It’s a quick way to confirm column alignment without external tools.
