Restructuring .csv data as .tsv changes the serialization without touching the values themselves. A .csv file is a comma-separated values table: plain-text rows with commas between fields, optionally quoted. It is probably the most widely produced data format in existence, emitted by everything from banking portals to lab instruments.
A .tsv file stores a table as plain text with one record per line and a tab character between columns. It is CSV's stricter sibling: because literal tabs almost never occur inside data, most TSV files need no quoting rules at all. For this route the practical draw is trivially parseable — split each line on tab, no state machine required and pastes directly into and out of Excel and Google Sheets, because spreadsheet clipboards already speak tabs — balanced against a single stray tab inside a value silently shifts every following column, which is worth knowing before you commit a large batch.
Why convert CSV to TSV?
The practical trigger for this conversion is usually a mismatch: with .csv, no type information — Excel famously strips leading zeros and mangles dates on open. Switching to .tsv buys you trivially parseable — split each line on tab, no state machine required, which is why it is the better fit for database dumps — PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
CSV vs TSV at a glance
| Aspect | CSV table (.csv) | TSV table (.tsv) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | fields containing commas, quotes, or newlines are wrapped in double quotes with embedded quotes doubled — the rule that breaks every naive split-on-comma parser | one record per newline-terminated line, with fields split on the tab character (U+0009) |
| Strongest at | exports from databases, CRMs, and banking systems | database dumps — PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs |
| Weak spot | no type information — Excel famously strips leading zeros and mangles dates on open | a single stray tab inside a value silently shifts every following column |
Pick TSV as the output
Select .tsv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TSV is selectable, the route is real and validated.
Convert on your device
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TSV file. Outputs keep the original filename with the .tsv extension.
CSV to TSV questions, answered
Will converting CSV to TSV lose quality?
There is no visual quality to lose — csv is text-oriented and tsv is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert CSV files here?
Yes — the .csv file is processed inside your browser tab and never uploaded. The restructuring is plain local parsing — your data is never posted to a server for processing. Close the tab and the file is gone from memory.
Where will the TSV file work?
Every spreadsheet application imports TSV, command-line tools handle it natively, and any text editor opens it — though column alignment on screen can be misleading. Browsers treat it as downloadable plain text.
Will the TSV file be bigger or smaller than my CSV?
It depends on the content: one record per newline-terminated line, with fields split on the tab character (U+0009). Convert one representative file first and compare before batch-processing a large set.
Can I convert TSV back to CSV?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .csv → .tsv → .csv is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
