TSV Tester

World's Simplest TSV Tool

Simple and free online TSV tester. Just paste a Tab-Separated Values table in the form below, and this tool will run checks for row structure, empty cell values, quote pairing, comments, empty rows, short rows, and extra spacing. In the options, you can set which row, cell, and spacing cases are allowed in your TSV input and which ones should appear as failed checks. Created by programmers from team Browserling.

What Is a TSV Tester?

This online tool tests Tab Separated Values (TSV) files for row, cell, and spacing issues. You can paste a TSV table into the input area, and the program will check the tab layout, quoted cells, row lengths, comment rows, empty lines, empty values, missing cells, and spaces that appear before or after values. The test rules can be adjusted in the options. You can let comment lines pass the test by setting their prefix, allow empty lines in TSV, allow empty values in cells, and allow rows with missing records. You can also decide whether left-side spaces and right-side spaces should fail the test or be ignored. If the TSV data passes the selected checks, a green badge appears in the output area. If the data fails, the tool displays a red badge and prints a numbered test report that shows what went wrong and which row each problem occurred in. For large or broken TSV files, you can limit the number of problems printed and show only the selected number of failed checks. Tsv-abulous!

TSV Tester Examples

Run a City TSV Test

In this example, we use a small travel-style TSV table with city and country columns. The input has a clean tab-separated structure: each city is paired with one country, and every row contains the same number of cells. Since the file has no comment rows, empty lines, empty values, missing cells, spacing problems, or quote problems, it passes all enabled checks.

city country Oslo Norway Lima Peru Cairo Egypt Seoul Korea

Check TSV Table Dimensions

In this example, we test a TSV water sample table for incomplete records only. Our TSV reader expects a rectangular table where each row has the same number of values as the header row, so the row and column dimensions must remain intact. This run allows comments, empty lines, empty values, and edge spaces, but it still blocks missing cells. The report finds two incomplete-data failures and shows their exact locations: rows 3 and 5.

sample check status A1 pH pass A2 turbidity A3 chlorine pass A4 nitrate A5 hardness pass
Error 1 title: Incomplete TSV Data message: The file has missing values. row: 3 Error 2 title: Incomplete TSV Data message: The file has missing values. row: 5

Strictly Test a Card List TSV

In this example, we run a strict test on a TSV table of playing cards. The table should have five cells in every row: card, suit, rank, color, and deck. Every minor formatting issue is treated as a failed check, including comment rows, empty lines, empty values, missing cells, leading spaces, trailing spaces, and unfinished quotes. The result limit is disabled, so the tester prints all nine failures found across the card deck data and explains each problem clearly enough to make the TSV easy to fix.

card suit rank color deck # playing card data Ace spades A black standard King hearts K red standard Queen diamonds red standard Jack clubs J black standard Nine hearts 9 red Ten spades "10 black standard
Error 1 title: TSV Contains Comments message: The file contains comments starting with "#". row: 2 Error 2 title: TSV Contains Trailing Spaces message: The file contains trailing spaces. row: 3 Error 3 title: TSV Contains Empty Lines message: The file contains empty lines. row: 4 Error 4 title: TSV Contains Leading Spaces message: The file contains leading spaces. row: 5 Error 5 title: TSV Contains Empty Values message: The file contains empty values. row: 6 Error 6 title: TSV Contains Leading Spaces message: The file contains leading spaces. row: 7 Error 7 title: Incomplete TSV Data message: The file has missing values. row: 8 Error 8 title: Incomplete TSV Data message: The file has missing values. row: 9 Error 9 title: Missing Quote message: Quoted field is unterminated. row: 9
