Does my BibTeX file leave my computer?

No. The conversion runs entirely in your browser using the citation-js library. Nothing is uploaded to DEEPNOTIS or any other server.

Why should I convert from BibTeX to CSL JSON?

BibTeX is commonly exported by one group of tools; CSL JSON by another. Converting lets you move your references between reference managers, LaTeX workflows, and institutional repositories without re-entering anything.

Do I lose any metadata in the conversion?

The converter maps every field that has a direct equivalent in the target format. Format-specific extensions (e.g. JabRef groups, Zotero tags) that don't exist in the target format are dropped — and the converter flags which ones so you can decide what to do.

What is BibTeX?

The default bibliography format for LaTeX documents. Flat-text, brace-delimited.

@article{smith2020, author={Smith, J.}, title={Example}, year={2020}, journal={Nature}}

What is CSL JSON?

The Citation Style Language JSON format. The modern interchange standard.

[{"id":"smith2020","type":"article-journal","title":"Example","author":[{"family":"Smith"}]}]

Why convert from BibTeX to CSL JSON?

Different reference managers and academic workflows expect different formats. BibTeX is commonly produced by some tools, while CSL JSON is what others ingest. Converting lets you bring your existing references into a new tool without re-entering them by hand.

Move your library between Zotero, Mendeley, EndNote, JabRef, Citavi, and Paperpile.
Bring web-clipped references into LaTeX workflows (BibTeX is required by most LaTeX bibliography styles).
Submit references to institutional repositories that mandate a specific format.
Backup your library in a portable, future-proof format.

Need more than a one-off conversion?

DEEPNOTIS keeps your references in a unified format inside your document — export to any format, any time, without round-tripping through separate tools.
