TSV Column Trimmer

World's simplest tsv tool
Simple and free online TSV value trimmer. Just paste a TSV table and choose whether to trim the whole table or only specific columns. You can remove spaces from the left side, right side, or both sides of selected fields, and you can also clean messy input by skipping comment rows and removing empty rows. Created by programmers from team Browserling.

What is a TSV Column Trimmer?

learn more about this tool
This online tool removes whitespace around values in Tab Separated Values (TSV) tables. Trimming is an operation that removes extra leading and trailing whitespace from data fields. These spaces can appear when TSV data is copied from spreadsheets, logs, reports, or database exports, and they can make filtering, sorting, and matching unreliable. Because both tabs and spaces are visually hidden, it is often hard to tell whether two TSV values are separated by a tab only or by a tab plus extra spaces. Cleaning this manually can be risky, as deleting the wrong invisible character may remove a tab delimiter and break the table structure. This tool reads the input as TSV data, keeps the tab delimiters intact, and trims only the columns you choose. You can trim every TSV column at once, select columns by their numeric positions, or match columns by the text in the first header row. Position mode supports single columns such as "2", lists such as "1, 4", ranges such as "2-5", mixed selections such as "1, 3-6", and reverse positions such as "-1" for the last column. Header mode lets you enter one or more column titles, one per line. If a TSV has repeated headers, you can trim just the first matching column or trim all duplicate header matches. Removing leading whitespace is called left-trimming, and removing trailing whitespace is called right-trimming. You can enable both operations simultaneously or use only one by selecting the appropriate options. You can also decide whether the first row should be trimmed together with the data rows or left exactly as it was. For messy TSV inputs, the cleanup options can remove blank rows and skip comment rows that start with a marker such as "#" or "//". Tsv-abulous!

TSV Column Trimmer examples

Countries and Their Capitals
In this example, we trim columns that contain country names and their capital cities. We enable trimming for every column and remove extra whitespace from both the left and right sides of each TSV value. The result keeps the same table structure but removes the unwanted spaces around all fields.
Austria — Vienna Belarus — Minsk Canada — Ottawa France — Paris Germany — Berlin Ireland — Dublin Italy — Rome Japan — Tokyo Poland — Warsaw

Trim all TSV values.
Remove all leading whitespaces in TSV columns.
Remove all trailing whitespaces in TSV columns.
Trim the first TSV row.
Set the marker for TSV comment rows to remove.
Remove TSV rows that contain no visible values.
Color Shades
This example applies only the trim-left function to TSV columns with color shades. It removes whitespaces from the beginning of odd columns (one and three) because we entered "1, 3" in the column positions option.
Blue Red Yellow Green Azure Carmine Gold Mint Capri Lava Lemon Olive Indigo Maroon Sunglow Lime Iris Crimson Maize Avocado Cyan Coral Citrine Emerald Teal Auburn Cream Celadon
"Blue " " Red " "Yellow " " Green" "Azure " " Carmine" "Gold " " Mint" "Capri " " Lava " "Lemon " " Olive" Indigo " Maroon " Sunglow " Lime" "Iris " " Crimson " "Maize " " Avocado" "Cyan " " Coral " Citrine " Emerald" "Teal " " Auburn " "Cream " " Celadon"

TSV Food
In this example, we trim selected TSV columns by their header names. The table has four columns: "veg", "fruit", "meat", and "fish". We enter "veg", "fruit", and "fish" in the header names option, so only these three columns are trimmed. Header trimming is also enabled, so the selected header cells are cleaned together with the data rows. Before trimming, the tool removes the empty rows and skips the "# seasonal list" comment row.
veg fruit meat fish carrot apple beef carp celery grape veal salmon # seasonal list tomato lemon lamb trout beet mango pork tuna corn melon bacon perch onion peach liver pike
veg fruit " meat " fish carrot apple " beef" carp celery grape " veal " salmon tomato lemon " lamb " trout beet mango " pork " tuna corn melon " bacon" perch onion peach " liver" pike
