When to Use CSV vs TSV
- Use CSV when sharing data with non-technical users (Excel opens CSV by default)
- Use TSV when working with Unix command-line tools (awk, cut, sort use tabs by default)
- Use TSV when your data contains many commas (avoids quoting complexity)
- Use CSV when your data contains tabs (tabs in values break TSV parsing)
- Use TSV for bioinformatics and data science pipelines (TSV is the standard in these fields)
Use the CSV to TSV Converter at techconverter.me to convert between CSV and TSV formats instantly, with correct handling of quoted fields, embedded delimiters, and line endings.
Examples
Example 1: Basic CSV to TSV Conversion
Input CSV:
id,name,city,country
1,Alice Johnson,New York,USA
2,Bob Smith,London,UK
3,Carol White,Paris,France
Output TSV (tabs shown as →):
id→name→city→country
1→Alice Johnson→New York→USA
2→Bob Smith→London→UK
3→Carol White→Paris→France
The commas are replaced with tabs. No quoting is needed because none of the values contain tabs.
Example 2: Handling Values with Commas (CSV → TSV)
In CSV, values containing commas must be quoted. When converting to TSV, the quotes are removed because commas are no longer the delimiter:
/* Input CSV */
id,name,address
1,Alice Johnson,"123 Main St, Apt 4"
2,Bob Smith,"456 Oak Ave, Suite 100"
/* Output TSV */
id→name→address
1→Alice Johnson→123 Main St, Apt 4
2→Bob Smith→456 Oak Ave, Suite 100
The commas inside the address values are preserved as literal characters. The surrounding quotes are removed since they are no longer needed.
Example 3: Handling Values with Tabs (TSV → CSV)
When converting TSV to CSV, values that contain tab characters need special handling since tabs are the TSV delimiter:
/* Input TSV — value contains a tab */
id→name→notes
1→Alice→"Has a tab[TAB]in notes"
/* Output CSV — tab replaced with space */
id,name,notes
1,Alice,Has a tab in notes
Configure the tool to replace embedded tabs with spaces, encode them as \t, or remove them entirely depending on what your target system expects.
