How to Convert Between Citation Styles: APA, MLA, Chicago, and More

Why You'd Need to Convert

The most common reasons to convert a paper's citations from one style to another: a professor changes the required style after you've drafted; you're adapting a paper for submission to a journal with different requirements; or you're repurposing research from a class that used one style for a new project requiring another.

What Actually Changes When You Convert

• In-text citation format — author-date parenthetical (APA, Harvard) vs. author-page (MLA) vs. numeric superscript or bracket (Vancouver, IEEE) vs. footnote (Chicago NB)
• Reference list name and ordering — "References" (APA, Harvard) vs. "Works Cited" (MLA) vs. "Bibliography" (Chicago) vs. numbered list in citation order (Vancouver, IEEE)
• Author name format — initials only (APA: Smith, J.) vs. full first name (MLA: Smith, John)
• Title capitalization — sentence case for articles (APA) vs. Title Case (MLA, Chicago)
• Punctuation between elements — periods, commas, and parentheses placement all differ
• Date placement — immediately after author (APA, Harvard) vs. near the end of the entry (MLA)

Converting In-Text Citations

This is the step most students forget — converting only the reference list and leaving the in-text citations in the old style's format. Both must change together; see our guides on types of citation systems and parenthetical vs. narrative citations for the in-text rules of each system.

Practical Conversion Tips

1. Keep a master list of full source details (author, title, container, date, DOI/URL) separate from any one style's formatting — this becomes your reusable "raw data" for any future conversion
2. Convert the reference list first, then go through the text converting each in-text citation to match
3. Re-check the new style's specific et al., capitalization, and page-number rules — don't assume they match the original style
4. Re-alphabetize or re-sequence the reference list according to the new style's ordering rule
5. Use a citation generator that supports both styles to avoid re-doing the formatting logic by hand

Frequently Asked Questions

Does the underlying source information ever need to change when converting?

No — author, title, publication date, and publisher information stay identical. Only the formatting, ordering, and punctuation around that information changes.

Is converting a whole paper's citations time-consuming to do manually?

It can be, especially for longer papers with many sources, since both the reference list and every in-text citation need updating. A citation generator that stores your source data once and re-outputs it in any style removes nearly all of that manual work.

Can I convert directly from a Word document?

If your sources were entered into Word's built-in citation manager, switching the style dropdown will reformat both in-text citations and the reference list automatically — though it's worth spot-checking the output against the style's actual rules, since built-in tools occasionally miss edge cases.
