Free online TXT to RIS converter

A reference manager or academic database may require RIS when a bibliography exists only as a plain-text file. Converting it makes authors, titles, dates, and identifiers importable as editable records instead of leaving them as unstructured notes.

What the TXT format is

TXT is a plain-text format with no required schema for bibliographic fields. Notepad, TextEdit, code editors, word processors saved as plain text, export utilities, and command-line programs create TXT files; researchers, students, libraries, and publishers commonly use them for notes and reference lists.

A bibliography in TXT may contain one citation per line, paragraphs copied from a database, tab-separated columns, or labels such as Author: and Title:. The .txt extension does not identify which text is an author, title, journal, DOI, or year, so no universal converter can interpret every TXT bibliography correctly.

What the RIS format is

RIS is a tagged bibliographic exchange format used by reference managers, library databases, and academic software. Each field uses a two-character tag followed by - ; a record normally begins with TY - and ends with ER -. Common tags include AU for author, TI for title, JO or JF for journal, PY for year, DO for DOI, and UR for URL.

RIS can store multiple records in one file and preserves searchable metadata better than copied citation text. The destination application applies italics, hanging indents, and a selected citation style; RIS itself stores bibliographic data rather than final document formatting.

Choose the conversion method

Formatted citations: Use a citation parser when each entry is a recognisable reference, such as an author followed by a title, journal, year, and pages. AnyStyle is a reputable online option: paste or upload the list at anystyle.io, parse it, inspect the detected fields, and export BibTeX or another supported structured format. Do not upload confidential material to an online service.

Open the exported BibTeX file in JabRef, then use File → Export and select RIS or Research Information Systems format. Import the resulting .ris file into Zotero, EndNote, Mendeley, Citavi, or the intended database and compare sample records with the source. AnyStyle cannot recover a DOI, author, or publication detail that the original citation does not contain; use a DOI lookup or the publisher database to complete missing fields.

Structured tables: If the TXT file uses fixed tab-separated columns, convert it with a script or spreadsheet workflow rather than a citation parser. For example, a file with headers author, title, year, journal, and doi can be processed by this Python script:

import csv
import sys

with open(sys.argv[1], encoding='utf-8', newline='') as source, open(sys.argv[2], 'w', encoding='utf-8', newline='') as target:
    for row in csv.DictReader(source, delimiter='\t'):
        target.write('TY  - JOUR\n')
        for author in row.get('author', '').split(';'):
            if author.strip():
                target.write('AU  - ' + author.strip() + '\n')
        for key, tag in [('title', 'TI'), ('journal', 'JO'), ('year', 'PY'), ('doi', 'DO')]:
            value = row.get(key, '').strip()
            if value:
                target.write(tag + '  - ' + value + '\n')
        target.write('ER  -\n\n')

Save it as txt_to_ris.py and run python txt_to_ris.py references.txt references.ris. In this example, separate multiple authors with semicolons. Change TY - JOUR for books, chapters, conference papers, or other record types, and add tags for volume, issue, pages, publisher, editors, and publication dates as required.

Unstructured notes: Copy each citation into a reference manager or enter its fields manually. Free-form prose, reading notes, or the full text of an article cannot be converted into accurate RIS records without identifying and structuring the bibliographic data first.

When renaming is enough

Open the file in a text editor and search for lines such as TY -, AU -, and ER -. If complete RIS records are already present, save a UTF-8 copy with an .ris extension and test it by importing it into the target application. Renaming does not convert ordinary prose or an untagged citation list.

Quality and compatibility checks

• Review every record. Plain text has no reliable field boundaries, so parsers commonly confuse author names, subtitles, journal names, page ranges, and dates.
• Use UTF-8 when the receiving program supports it to preserve accented and non-Latin characters. Older RIS readers may mishandle smart quotes, unusual dashes, or other Unicode punctuation.
• Keep one ER - terminator per record. Missing terminators can cause adjacent references to be merged during import.
• RIS implementations differ: JO and JF, PY and Y1, editor fields, and multiple publication dates may be handled differently by each application.
• Verify DOI values, URLs, author order, and record types, then remove duplicates after import. A text conversion normally does not fetch missing metadata or identify duplicates automatically.
