What Insert a TSV Column can do:

Insert a TSV Column helps you add a new column of data into an existing TSV dataset without needing a spreadsheet or script. Just paste your table, define the new column values, and choose where to place them. It handles different row lengths, trims cells cleanly, and updates live in your browser. You can export the result immediately for use elsewhere.

Example:

Original TSV:

id	name	age
1	Alice	30
2	Bob	25
3	Charlie	35

New Column:

country

US
CA

Insert at index: 1

Output:

1	US	Alice	30
2	US	Bob	25
3	CA	Charlie	35

Common Use Cases:

Use Insert a TSV Column to add metadata, notes, tags, country codes, or additional values to exported TSV files. It’s perfect for editors, researchers, and engineers who need to inject columns into clean data formats quickly and without Excel.
