Add your TSV file
Drop one or more .tsv files onto the converter above, or browse for them. They load into browser memory only. Nothing is uploaded, so there is no size-based pricing and no server queue.

Restructuring .tsv data as .cbor changes the serialization without touching the values themselves. 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.
A .cbor file holds Concise Binary Object Representation data: a binary format built on the JSON data model but standardized by the IETF, with a tag mechanism that lets it carry dates, big integers, decimals and arbitrary application types without inventing a convention for each one. For this route the practical draw is an actual IETF standard with a stable, versioned specification and tags express types JSON cannot, without breaking decoders that ignore them, balanced against tag semantics are only as portable as the two ends' agreement on them, which is worth knowing before you commit a large batch.
Why convert TSV to CBOR?
The practical trigger for this conversion is usually a mismatch: with .tsv, a single stray tab inside a value silently shifts every following column. Switching to .cbor buys you an actual IETF standard with a stable, versioned specification, which is why it is the better fit for WebAuthn and FIDO2 attestation and assertion payloads. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
TSV vs CBOR at a glance
| Aspect | TSV table (.tsv) | CBOR (.cbor) |
|---|---|---|
| Format type | Text-based: characters and structure, so there is no visual quality loss | Lossless: every pixel or sample is preserved exactly |
| How it stores data | one record per newline-terminated line, with fields split on the tab character (U+0009) | every item begins with a major type in the top three bits and a length or value in the remaining five, which makes decoders small enough for microcontrollers |
| Strongest at | database dumps, PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs | WebAuthn and FIDO2 attestation and assertion payloads |
| Weak spot | a single stray tab inside a value silently shifts every following column | tag semantics are only as portable as the two ends' agreement on them |
Pick CBOR as the output
Select .cbor in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if CBOR is selectable, the route is real and validated.
Convert on your device
Press Convert. The restructuring is plain local parsing, and your data is never posted to a server for processing.
Verify and download
Each result is checked before the download unlocks: where CBOR has a signature or a structure this converter can read back, the file is re-opened and parsed, and where it has neither, the check is that a non-empty file of the declared type came back. A result that fails is reported as an error instead of being offered for download, and outputs keep the original filename with the .cbor extension.
TSV to CBOR questions, answered
Will converting TSV to CBOR lose quality?
There is no visual quality to lose, because tsv is text-oriented and cbor is lossless-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 TSV files here?
Yes. The .tsv file is processed inside your browser tab and never uploaded. The restructuring is plain local parsing, and your data is never posted to a server for processing. Close the tab and the file is gone from memory.
Where will the CBOR file work?
Libraries are widely available for C, Rust, Go, Python, Java, JavaScript and .NET, and browsers speak CBOR indirectly through the WebAuthn API. Novus Convert normalizes .cbor locally into a JSON-compatible model and writes JSON, CSV, XLSX, YAML or YML. Tagged values that JSON cannot represent are converted to a documented textual form rather than being silently discarded.
Will the CBOR file be bigger or smaller than my TSV?
It depends on the content: every item begins with a major type in the top three bits and a length or value in the remaining five, which makes decoders small enough for microcontrollers. Convert one representative file first and compare before batch-processing a large set.
