What Delete TSV Comments can do:

Delete TSV Comments makes it easy to strip out lines that begin with a comment character useful when working with annotated datasets, logs, or TSV exports. It supports any single-character prefix (like #, ;, or //) and works entirely in your browser with no setup. You can also trim whitespace to avoid skipping lines accidentally. Whether you’re prepping a dataset for import or cleaning up raw logs, this tool lets you filter comments fast.

Example:

Input:

# metadata: user data
name	age	city
Alice	25	New York
# test record
Bob	30	Los Angeles

With Comment Prefix = # and Trim ON:

name	age	city
Alice	25	New York
Bob	30	Los Angeles

Common Use Cases:

You might use this when importing TSV data into a database that can’t handle comment rows, or when you want to clean up logs, sensor output, or analytics exports. It’s great for scripts, data prep, or simply sharing TSV without the clutter.
