Common Style Conversions

The Bulk Citation Converter handles every direction between major styles — and any of the 10,000+ CSL styles in between. A few of the most common conversions writers run into:

Convert MLA to APA Citation

Switching disciplines or moving from a humanities course to a social-science journal? Paste your MLA Works Cited list (in plain text, BibTeX, or RIS) and the converter rewrites every entry as APA 7 — author initials, sentence-case titles, italicized journal names, and full https://doi.org/ links — in one click.

Convert APA to MLA Citation

Going the other way? Drop in your APA reference list and get a properly formatted MLA 9 Works Cited, with full first names, title case, and the MLA container model applied to journals, anthologies, and websites.

Convert Chicago to APA (and back)

Chicago notes-and-bibliography and Chicago author-date entries both convert cleanly to APA 7. The tool also handles APA → Chicago for history, theology, and humanities papers that require notes-and-bib formatting.

Convert Harvard to APA

Harvard and APA share an author-date system but differ in punctuation, ampersand use, and DOI formatting. Paste a Harvard reference list to get a clean APA 7 version — or convert APA to Harvard if your institution uses the Harvard variant.

BibTeX or RIS → Any Style

Export from Zotero, Mendeley, EndNote, or Google Scholar and paste the file contents directly. The converter auto-detects BibTeX (@article) and RIS (TY - JOUR) and renders them in your target style.

Need a Style Not Listed?

Click More in the style picker for AMA, Vancouver, IEEE, Optica, ACS, Nature, Cell, and 10,000+ other journal styles backed by the Citation Style Language (CSL) registry.

Why You Need a Bulk Citation Style Converter

Converting APA to Chicago usually comes up when a paper crosses disciplines. A psychology grad student writes a chapter for a humanities edited volume. A social-science article gets repurposed for a history journal. A dissertation defended in one department gets reformatted for an interdisciplinary press. APA and Chicago author-date share a parenthetical (Author year) pattern, which makes the in-text changes minor; the bigger work is on the bibliography side, where punctuation, initials, and capitalization all differ.

Paste your APA list and the converter rewrites each entry in Chicago author-date by default — full first names instead of initials, title case instead of sentence case, periods between elements instead of commas. For Chicago notes-and-bibliography (the humanities default), click the More button in the style picker and select Chicago (Notes-Bibliography). Same conversion, different output punctuation. Both use the Citation Style Language engine Zotero and Mendeley use.

What inputs the converter accepts

Why bulk conversion beats one-at-a-time

Most online tools handle one citation at a time. Fine if you have one reference. Nightmare if you have eighty. The Bulk Converter runs the whole list as a single pass, which is what gets you consistency: same date format, same author rule, same DOI prefix, same italicization across every entry. That's the thing reviewers actually notice. A list that's almost consistent reads worse than one that's clearly wrong.

Common workflows

Switching Journals

Submitted to Nature, got a desk reject, redirecting to Cell? Different style guide. Paste the original reference list and reformat in the target journal's style without rewriting a single entry by hand.

Thesis Style Compliance

Universities each have their own thesis style guide. Convert your finished bibliography from APA, MLA, or Chicago into your institution's required style in one paste.

Zotero / Mendeley Export

Export .bib or .ris from your reference manager and convert the contents to a clean Works Cited list in your manuscript's style — no plug-in, no Word-add-in setup.

Cross-Discipline Collaboration

Co-authoring across fields? The medical co-author wants AMA, the engineering co-author wants IEEE, the humanities co-author wants Chicago. Convert each section into the agreed-on house style for the target venue in one click.

Cleaning a Legacy Bibliography

Re-using a reference list from an earlier paper but the journal has updated to APA 7? Bulk-convert APA 6 → APA 7 to pick up the sentence-case titles, full DOI URLs, and updated author conventions.

Reading-List Reformatting

Have a reading list in BibTeX from a course? Convert it to APA or MLA so you can drop it into your own bibliography as you write — no transcription, no errors.

Frequently Asked Questions

Which Chicago should I pick — author-date or notes-and-bibliography?

Author-date if the target venue is a social-science journal or any publication that uses parenthetical citations. Notes-and-bibliography if it's a humanities journal, a history monograph, a theology paper, or anything that uses footnotes. The default on this page is Chicago author-date because that's the closest match to APA's in-text style; switch via More if you need NB.

Will the converter give me full first names from APA initials?

No — if APA only gave initials, the converted Chicago entries also use initials. Chicago prefers full first names, so if first names matter for the venue, look up the missing authors and add them by hand. The parsed entries are usually only a few names short of complete.

Does this generate footnotes for me?

It generates the bibliography entries. Chicago footnotes (the short forms used after first reference) you write inline in the manuscript as you cite, drawing from the bibliography entries the converter produces. If you need a full footnote form for a single citation, the Chicago Footnote Generator handles those one at a time.

What about Harvard to APA?

Harvard and APA share an author-date system but disagree on punctuation, ampersand use, the order of elements, and whether DOIs come as bare strings or full URLs. Paste any Harvard list and the converter normalizes to APA 7. APA to Harvard works the other way if your institution uses one of the Harvard variants (Cite Them Right, Anglia Ruskin, others).

Does it handle BibTeX and RIS files?

Yes. Export from Zotero, Mendeley, EndNote, JabRef, Overleaf, or any database that supports BibTeX or RIS, and paste the file contents in. The converter auto-detects the format — looking for @article or @book on the BibTeX side, TY - JOUR on the RIS side — and renders the entries in your chosen style.

What if my style isn't APA, MLA, Chicago, or Harvard?

Click More in the style picker. You'll get AMA, ACS, IEEE, Vancouver, Optica, Nature, Cell, JAMA, BMJ, plus 10,000+ other journal- and discipline-specific styles. All backed by the Citation Style Language (CSL) registry, the same registry Zotero and Mendeley use under the hood.

How accurate is the parser?

For well-formatted bibliographies in any major style, accuracy sits in the high 90s. Edge cases that sometimes want a touch-up: very old reference lists with hand-typed inconsistencies, non-Latin-script entries (Cyrillic, Chinese), house styles that mix numbered and author-date conventions in the same list. The converter shows you the parsed fields alongside the formatted output, so you can catch an entry that looks off before it ships.

Is there a limit on how many references I can convert at once?

Practically no. Lists of 100+ entries are routine. For very long bibliographies (500+), break them into batches of a few hundred. The response stays snappy and you can spot any parser hiccups before they propagate. Each batch is independent — no ordering or consistency penalty for splitting.

Will my data be saved or used to train models?

No. Pasted bibliographies live in memory while the request runs and are gone once the response returns. We don't retain the input, the parsed records, or the formatted output beyond the active session. Nothing trains a model. The privacy policy spells the specifics out.

How much does it cost?

The converter runs on the citation processor itself — no AI credits required. Conversion is free. You may see a prompt to sign in if you want to save converted lists to your Works Cited library, but the conversion stays free either way. Top-up packs for the AI-powered tools live on the pricing page.
