What is a TSV Column Inserter?

learn more about this tool
This online tool inserts new fields into the middle of a Tab-Separated Values (TSV) table. This is a quick way to expand a table without manually moving cells or counting tab characters. The tool automatically places the inserted column block between the existing columns, helping avoid misplaced fields and broken TSV rows. In the options, you can specify the column data to insert into the TSV. To insert a single column, place the values vertically, with one value per line. To insert two, three, or more columns at once, enter the new data in regular TSV format, with two, three, or more tab-separated values on each line. The insertion point can be selected by a zero-based column number, where 0 places the new fields before the first column. You can also use negative column positions to count from the end of the table. For example, -1 inserts the new fields at the end of the TSV. The insertion point can also be selected by an existing header name, and the tool will place the new columns right after that header. If the same header appears more than once, you can enable the match-all option to insert the new columns after every matching header, or disable it to insert them only after the first matching header. The tool also offers several options for handling cases where the input TSV and the inserted column data have different row or field counts. You can keep uneven rows as they are, remove incomplete rows, insert empty values where data is missing, or use a custom value to fill missing fields. You can also clean the TSV by removing empty lines and skipping comment rows before inserting the new columns. Tsv-abulous!

TSV Column Inserter examples

Click to use
Insert a Shirt Size Column
This example updates a small TSV shirt table by inserting a new "size" column. The original table has "item", "color", and "price" columns, and position 2 places the inserted values after "color". The result adds the size for each shirt while keeping the price column at the end.
item color price shirt blue 18 hoodie gray 35 jacket black 64
item color size price shirt blue M 18 hoodie gray L 35 jacket black S 64

Insert Hub Fields by Header
In this example, we insert two new columns by matching a header name. The input TSV has two columns named "date": the first one shows the order date, and the second one shows a later ship date. We use header-name mode with "date" as the target and turn off the match-every-header option, so the new "hub" and "dock" columns are inserted only after the first "date" column. The second "date" column remains where it was.
order date qty date K-14 Mon 6 Thu K-22 Tue 9 Fri
order date hub dock qty date K-14 Mon East D2 6 Thu K-22 Tue West D4 9 Fri

Insert Match Statuses at the End
This example inserts a status column by using the negative column position -1, which places the new field after the current last column. The input also contains an empty row and a commented row, so the cleanup options remove both before the new data is inserted. The inserted status column has values for only two teams, so the missing third status is filled with the custom value "standby".
team coach Lions Mira # practice game Falcons Omar Wolves Lena
team coach status Lions Mira ready Falcons Omar waiting Wolves Lena standby
