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.
TSV to BSON
Restructuring .tsv data as .bson changes the serialization without touching the values themselves. Free, private, and validated: the file never leaves your browser.

Restructuring .tsv data as .bson 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 .bson file holds BSON: the binary document format MongoDB stores and transmits. It looks like JSON with types added (every field is length-prefixed and carries a type byte) which makes documents skippable during a scan and gives them an ObjectId, a real date type, and 32- and 64-bit integers distinct from doubles. For this route the practical draw is exact numeric types and native dates, unlike JSON and length prefixes make skipping and partial reads cheap, balanced against often larger than the equivalent JSON, because of length prefixes and field names repeated per document, which is worth knowing before you commit a large batch.
Why convert TSV to BSON?
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 .bson buys you exact numeric types and native dates, unlike JSON, which is why it is the better fit for inspecting a mongodump export without restoring it to a database. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
TSV vs BSON at a glance
| Aspect | TSV table (.tsv) | BSON (.bson) |
|---|---|---|
| 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) | a document is a little-endian int32 total length, a sequence of typed elements, and a terminating null byte |
| Strongest at | database dumps, PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs | inspecting a mongodump export without restoring it to a database |
| Weak spot | a single stray tab inside a value silently shifts every following column | often larger than the equivalent JSON, because of length prefixes and field names repeated per document |
Pick BSON as the output
Select .bson in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if BSON 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 BSON 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 .bson extension.
TSV to BSON questions, answered
Will converting TSV to BSON lose quality?
There is no visual quality to lose, because tsv is text-oriented and bson 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 BSON file work?
Official MongoDB drivers for every major language decode BSON, and standalone libraries exist for Python, Java, Go, Rust and JavaScript. Novus Convert decodes .bson in the browser and writes JSON, CSV, XLSX, YAML or YML, handling non-JSON types explicitly: ObjectId and Decimal128 become their canonical string forms and Binary is reported rather than mangled into text.
Will the BSON file be bigger or smaller than my TSV?
It depends on the content: a document is a little-endian int32 total length, a sequence of typed elements, and a terminating null byte. Convert one representative file first and compare before batch-processing a large set.
