TSV (Tab-separated values) is a simple, text-based file format for storing tabular data.
Records are separated by newlines, and values within a record are separated by tab characters. The TSV format is thus a delimiter-separated values format, similar to CSV (comma-separated values).
Here are some TSV conversion tools, Convert data between TSV and other file types, between TSV and databases, Merge TSV files, Split TSV files.
