What this tool does

TSV to CSV Converter turns tab-separated exports, copied spreadsheet ranges, database query results, and command-line output into CSV that can be imported by analytics tools, CRMs, finance systems, and data pipelines. Paste TSV or load a local .tsv or .txt file, then copy or download standards-friendly CSV. Cells containing commas, quotes, tabs, or line breaks are escaped correctly, and ragged rows are padded with empty cells so downstream importers receive a stable column shape.
