Simple and free online TSV column appender. Just paste Tab Separated Values into the form below, add the trailing column data in the options, and the tool will add those fields to the end of each row. You can attach a single column or multiple tab-separated columns, skip blank and commented rows, and fill missing appended fields with empty or custom values.

This online tool expands a Tab Separated Values (TSV) table by adding extra columns after the last existing field in each row. It is useful when you already have a TSV table and want to attach new row data, such as statuses, owners, categories, notes, IDs, or other trailing fields, without changing the original columns. To append one column, enter one value for each input row in the append options. To append several columns, enter tab-separated values on each line. The tool joins each input row with the matching append row, so the added fields appear on the right side of the TSV. When the appended data has fewer rows than the input TSV, some input rows do not receive new fields on the right. In this case, the tool can keep those rows as they are, skip incomplete rows, add empty fields, or insert a custom fill value. You can also clean the input before appending by removing blank rows and skipping comment rows with a selected marker. If the new fields should go at the beginning instead of the end, try Prepend TSV Columns. If they should appear in the middle of the table, use Insert TSV Columns. Tsv-abulous!

In this example, we append one new column to a TSV train ticket list. The input table already has "ticket", "car", "class", and "seat" columns. In the options, we enter the "window" column, and the tool adds it after the last column.
In this example, we append two new columns to a TSV puzzle table. The input has puzzle names and difficulty modes, but it also contains blank rows and a "# bonus round" comment line. The cleanup options skip these non-data rows first. Then the tool appends the "score" and "rank" columns to the right side of each remaining puzzle row.
This example adds a status column to the end of a TSV bakery order list. The input contains four bakery orders, but the appended data includes statuses for only the first three orders. Because the final order does not receive a status from the appended column, the tool uses the custom fill value "check-order" for that last cell.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
