Incomplete TSV Value Filler

World's Simplest TSV Tool

Simple and free online incomplete TSV value filler. Just paste a Tab-Separated Values table into the form below, and this tool will complete rows that do not have enough tab-separated fields. You can set custom text for missing cells, fill empty cells too, and choose what happens to comment rows and blank TSV rows. Created by programmers from team Browserling.

What Is an Incomplete TSV Value Filler?

This tool fills missing and empty cells in Tab Separated Values (TSV) data. You can use it when TSV rows should all have the same column length, but some rows are missing cells or contain blank cells. For example, if the TSV file has a header with four columns and some data row has only three tab-separated values, then the fourth cell is missing in this row. The tool can find such cells that are not present in a TSV file and fill them with custom data. In the options, you can choose the text that will be inserted into the missing positions. You can add missing cells at the end of a row. In this case, all existing values stay in their current columns, and the new values are appended after them. This is useful for rows that are missing trailing fields. Or you can add missing cells at the beginning of a row. In this case, the existing values shift to the right. This is useful for rows that are missing leading fields. An empty cell is different from a missing cell. It is already part of the TSV row, but it has no real content. For example, the row contains a tab-separated cell, but this cell is empty or contains only space characters. The tool can also fill these empty cells with a custom text value. Rows that begin with the comment prefix can be dropped, kept unchanged, or handled as regular TSV rows. Blank TSV rows can also be dropped, kept as blank spacing, or processed as table rows. If you only want to find all the missing and empty values in the TSV without fixing them, use our Find Incomplete TSV Values tool. Tsv-abulous!

Complete Vinyl Pressing Rows

In this example, we repair a short TSV list of vinyl pressings. The table should have three cells in every row: artist, release title, and plant code. Two rows are missing the final plant code, so the tool appends the text "TBD" to the end of those rows while leaving the complete rows unchanged.

artist release plant Nia Bloom VX1 Oto Drift Mara Pulse VX3 Lux Echo

Fill Empty Perfume Catalog Cells

In this example, we clean a TSV catalog of perfume vials. The table actually has no missing values, as every row contains three tab-separated values. However, some of these values have no visible content. The "fig" row has an empty base cell, the "iris" row has an empty vial cell, and the "cedar" row has a base cell that contains only a space. We enable empty-cell filling and use "none" as the replacement text, so the tool replaces these empty base and vial values with the chosen text.

scent base vial amber vanilla V1 fig V2 iris powder cedar V4 mint green V5
scent base vial amber vanilla V1 fig none V2 iris powder none cedar none V4 mint green V5

Repair a Craft Supply TSV File

In this example, we repair a small TSV inventory for craft supplies. The table has three columns: box, supply, and count. Most rows already have a box code, a supply name, and a count value. However, the "markers" and "tape" rows start with the supply name, so they are missing the first cell with the box code. We add "no-box" at the beginning of these rows, so the supply names move into the correct column. The B2 row already has three cells, but its supply cell is empty, so we replace this empty value with "unknown". The comment row and the blank separator row are kept unchanged in the output.

box supply count A1 glue 4 markers 12 B2 3 tape 2 # spare supplies C3 paper 20
box supply count A1 glue 4 no-box markers 12 B2 unknown 3 no-box tape 2 # spare supplies C3 paper 20
