Convert CSV to TSV
Transform pasted text with the csv to tsv and copy the cleaned output.
Direct Answer
Use the CSV to TSV converter when a tool expects tab-separated values instead of commas, or when you want to paste tabular data directly into a spreadsheet app so it lands in separate cells automatically.
Why Convert Comma-Separated Data to Tabs
Tab-separated data behaves differently from comma-separated data in a few practical ways that make TSV the better choice for certain workflows.
- Pasting tab-separated text directly into Excel, Google Sheets, or Numbers splits it into separate cells automatically, without triggering an import wizard the way pasted CSV text sometimes does.
- Command-line tools like cut and awk default to tab as a field separator, so TSV input avoids extra flags.
- A tab character is far less likely to appear naturally inside text data than a comma is, which reduces the chance of ambiguous or misparsed fields.
- Legacy systems and scientific or bioinformatics data formats commonly require TSV specifically, not CSV.
What Happens to Quoted CSV Fields When Converting to TSV
This is the direction-specific detail that trips people up: CSV has a standard quoting convention, but TSV generally doesn't, so converting from CSV to TSV means deciding what to do with quotes and any literal tabs hiding inside a field.
- A field that was quoted in the CSV only because it contained a comma no longer needs quotes once the delimiter is a tab, so the quotes are typically dropped.
- A literal tab character inside a CSV field is illegal in plain TSV, since tabs are the delimiter, so it's usually replaced with a space or an escape sequence during conversion.
- A literal newline inside a quoted CSV field is normally collapsed to a space or escaped, since standard TSV expects exactly one record per line.
- Quote characters that existed purely for CSV escaping purposes are stripped, since TSV has no equivalent quoting mechanism to preserve them for.

Frequently Asked Questions
Does converting from CSV to TSV remove the quotes around my fields?
Yes, quotes that were only present in the CSV to escape a comma, quote, or newline inside a field are removed, since TSV doesn't use quoting the same way CSV does and a tab delimiter makes those commas harmless. A field that genuinely needs to preserve a literal double-quote character keeps that character; it's the wrapping quotes used purely for CSV escaping that go away.
What happens to a field that had a comma inside quotes once it becomes TSV?
The comma is preserved as a literal character in the field's text, since it's no longer acting as a delimiter once the file uses tabs instead. This is actually one of the benefits of converting to TSV: fields with commas, like '1,000' or 'Smith, John', no longer need any special quoting to stay intact as a single field.
What happens if a field contains an actual tab character?
This is the core direction-specific gotcha: a literal tab inside a field would be indistinguishable from the column delimiter in plain TSV, since TSV has no standard quoting convention the way CSV does. The converter typically replaces an embedded tab with a space, or in some implementations escapes it, to keep the row structure intact rather than silently creating an extra column.
Why does pasting CSV directly into Excel put everything in one cell, but TSV doesn't?
When you paste plain text into a spreadsheet, most spreadsheet apps split it into cells based on tab characters, not commas, since tabs are the clipboard convention for 'this is a new cell.' Comma-separated text pasted directly lands as one long value per row in a single cell unless you go through an explicit Text to Columns or import step, which is exactly why converting to TSV first makes pasting work as expected.
What happens to a field with a newline character inside it during conversion?
A quoted CSV field can legitimately contain a newline and still count as one field spanning multiple lines in the raw file. Converting to TSV usually collapses that embedded newline into a space, since plain TSV expects one record per physical line and preserving a real line break inside a field would otherwise split it into what looks like a new row.
Is TSV smaller or larger than the equivalent CSV file?
TSV is often slightly smaller for data with many text fields that contained commas, since those fields no longer need surrounding quote characters. The difference is usually minor and depends heavily on how much of your original data actually needed CSV quoting in the first place.
Do I need to change the file extension after converting?
Yes, rename the output to a .tsv extension so that any tool you open it with, or a person receiving the file, correctly assumes tab-delimited content rather than trying to parse it as comma-separated. Some tools infer the delimiter from content rather than extension, but relying on that isn't safe across all software.
Will numbers or dates be reformatted during the CSV to TSV conversion?
No, cell values are carried over as-is; only the delimiter character and quoting are affected. A number or date is treated as plain text throughout the conversion and isn't reparsed or reformatted.
Can I convert a semicolon-delimited CSV directly to TSV?
Yes, the source delimiter doesn't need to be a comma specifically; a semicolon-delimited European-style CSV converts to TSV the same way, since the tool parses the source file's actual delimiter first before re-serializing it with tabs.
Why would I choose TSV over CSV for a data export?
TSV is a good choice when the data is likely to contain commas (currency values, addresses, thousands separators) since those no longer need special handling, and when you want the file to paste cleanly into a spreadsheet or command-line tool without extra import steps. CSV remains more universally expected by import forms and general-purpose tools, so the choice depends on your destination.
Does TSV support quoted fields at all?
There's no single official standard for TSV quoting the way RFC 4180 defines it for CSV, so support varies by implementation; some tools allow quoted fields, most don't expect them at all. Because of this inconsistency, it's safer to avoid characters that need quoting (tabs, newlines) inside TSV fields rather than rely on a particular tool supporting quoting correctly.
What happens to leading/trailing spaces in a field during conversion?
Spaces inside a field's text are preserved by default during delimiter conversion alone, since that's a separate concern from changing the delimiter character. If you also want stray whitespace trimmed, run the file through a CSV cleaner either before or after converting the delimiter.
