Free online RIS to TEX converter

References exported from a library database often need conversion before they can be cited in a LaTeX manuscript. The usual result is a .bib bibliography database used by a .tex source file, not RIS tags pasted directly into the document.

What the RIS format is

RIS is a tagged plain-text format for exchanging bibliographic records between reference managers, library catalogs, academic indexes, and research databases. Each field begins with a two-character tag and a separator; common tags include TY for record type, AU for author, TI for title, JO for journal, PY for year, DO for DOI, and ER for the end of a record.

Web of Science, Scopus, PubMed, library catalogs, Zotero, EndNote, Mendeley, and RefWorks can import or export RIS records. RIS stores bibliographic metadata, not a complete typeset document.

What the TEX format is

A .tex file is editable TeX or LaTeX source containing document structure, text, commands, mathematical notation, tables, and citation references. A TeX engine such as pdfLaTeX or LuaLaTeX compiles it into PDF or another output format.

References are normally kept in a separate .bib file written in BibTeX or BibLaTeX syntax. The .tex source cites entries by generated keys such as \cite{smith2024}. This separation allows one bibliography database to support several documents and citation styles.

How to convert RIS data for a TEX document

The reliable workflow is RIS → BibTeX or BibLaTeX → LaTeX. A conversion that merely changes .ris to .tex does not produce valid LaTeX source.

With JabRef:

1. Install and open JabRef.
2. Use File → Import or the equivalent RIS import command for the JabRef version in use, select the .ris file, and import it into a library.
3. Inspect record types, author names, titles, dates, DOI values, page ranges, and journal or book details. Correct malformed or missing fields.
4. Use File → Export, choose BibTeX or BibLaTeX, and save the result as references.bib.

JabRef is useful when records need editing and citation-key management. Zotero, EndNote, and Mendeley can perform the same general operation: import RIS, review the records, and export BibTeX or BibLaTeX.

On 101convert.com, the RIS file can be converted for free without installing software. Treat the generated bibliography as an import that requires checking before compilation.

Add the bibliography to LaTeX

For BibLaTeX, add the exported database and bibliography commands to the .tex file:

\documentclass{article}
\usepackage[backend=biber,style=authoryear]{biblatex}
\addbibresource{references.bib}

\begin{document}
A cited work appears here \parencite{smith2024}.
\printbibliography
\end{document}

Run the compilation sequence from the project directory:

pdflatex manuscript.tex
biber manuscript
pdflatex manuscript.tex
pdflatex manuscript.tex

With the older BibTeX workflow, use commands such as \bibliographystyle{plain} and \bibliography{references}, then run pdflatex, bibtex, and pdflatex twice. The exact citation commands and style depend on the document class and bibliography package.

Quality and compatibility limits

RIS field coverage and tag conventions vary between exporters. Abstracts, keywords, URLs, editors, conference data, issue information, capitalization, and identifiers can be omitted or mapped incorrectly. Review duplicate records and verify authors, dates, titles, page ranges, DOI values, and entry types.

RIS does not define LaTeX citation keys. The importer or exporter generates keys, so existing commands such as \cite{smith2024} work only when the generated key matches them. Rename keys consistently if the manuscript already contains citations.

Protect capitalization that must remain unchanged in the .bib file, for example title = {A Study of {DNA} Repair}. Check non-ASCII characters, ampersands, percent signs, underscores, braces, and other characters that may require LaTeX escaping. Also confirm that the selected engine, bibliography processor, encoding, and citation package are compatible.
