Result

Are you familiar with the situation when you export data from a database in TSV format, and when importing to another system, everything breaks because a tab character was encountered in the text of the description, which shifted the columns?

Our TSV validator will quickly check the file structure completely confidentially (your data stays in your browser and is not transmitted anywhere). This is ideal for processing large databases.

The tool analyzes the number of columns in each line, detects empty values, problems with quotation marks, and incorrect line feed characters. You will receive an accurate report on the errors found.
