CSV File

File extension .CSV
CategoryDocument File
DescriptionCSV is a plain text format used for representing database tables. Each data box (cell) is enclosed in commas. Each line is a table row with data cells. It is a perfect format for transporting tables from one application to another. CSV files can be edited in OpenOffice Calc, MS Excel and many others. Being a plain text in actual fact, CSV tables are compatible with various text editing programs. It doesn't support formatting, so any data structuring is made with the use of special characters.

TSV File

File extension .TSV
CategoryDocument File
DescriptionTSV facilitates exchange of tabular database between utilities using a variety of extensions. TSV files look like textual tables and are compiled of records (lines), which, in turn, are made up of fields. Each field forms a succession of characters, except TAB symbols, which serve as field separators. The top line is indeed the header, since it sets names for each field and defines their function, and the remaining lines have as many fields as the top one. TSVs can be rendered in utilities designed for creating databases and electronic tables. These materials can be conveniently exported to Excel.

CSV to TSV Converter — Frequently Asked Questions ▼

What is the difference between CSV and TSV?

Both formats store tabular data as plain text. CSV (Comma-Separated Values) uses a comma as the field delimiter; TSV (Tab-Separated Values) uses a horizontal tab character (ASCII 0x09). The structural difference is one character. The practical difference is that commas frequently appear inside data values (addresses, numbers formatted with thousand separators, descriptions), which forces CSV to wrap those fields in double quotes. Tab characters rarely appear in data, so TSV rarely needs quoting, making it simpler to parse in many pipelines.

Will fields containing commas or quotes be handled correctly?

Yes. The converter reads RFC 4180-compliant CSV, correctly handling quoted fields that contain commas, embedded newlines, and escaped double quotes (""). In the TSV output, those fields are written unquoted with the tab delimiter, and any literal tab characters inside a field are replaced or escaped to keep the TSV valid. The cell values are preserved exactly.

Does the converter preserve the header row?

Yes. The first row is treated as a header and written as the first line of the TSV output, with each column name separated by tabs. No row is added, removed, or reordered during conversion.

What encoding does the output TSV use?

The output is UTF-8, which matches the most common encoding of modern CSV files. If your source CSV uses a different encoding (Windows-1252, Latin-1, etc.) and contains non-ASCII characters, upload the file as-is; the converter detects encoding and writes UTF-8 TSV output. Check the first few rows in a text editor if you see unexpected characters.

What is the maximum file size for the online converter?

The online converter accepts CSV files up to 50 MB. A 50 MB CSV typically contains several million rows depending on the number and width of columns. For larger exports from databases or analytics platforms — where CSV files can reach hundreds of megabytes or gigabytes — process them in batches or use the desktop Total Excel Converter: TotalExcelConverter.exe C:\Data\*.csv /tsv /out C:\TSV\.

Can I automate CSV to TSV conversion for a recurring data pipeline?

Yes. The desktop Total Excel Converter supports command-line batch conversion: TotalExcelConverter.exe C:\Input\*.csv /tsv /out C:\Output\. You can schedule this command with Windows Task Scheduler to run on a timetable, or call it from a shell script as part of a data ingestion or ETL workflow. The online converter handles one file at a time and is best suited for occasional, ad-hoc conversions.
