Vancouver to ASA converter

Paste Vancouver references, get ASA. Free, no sign-up.

Paste references written in Vancouver and get them back in ASA, ready to copy into Word or Google Docs. The main changes: numbered in-text citations become author–date citations, titles switch to title case and the list is alphabetical by first author’s surname. CiteSwap looks each reference up in the open Crossref catalogue, so authors, years and page numbers come from the publisher’s record rather than being rewritten by hand.

When to use ASA

ASA is the house style of American sociology journals and many sociology departments. It is published by the American Sociological Association; CiteSwap follows the ASA Style Guide, 6th/7th edition.

Vancouver is more common in medicine, nursing, dentistry, while ASA is usual in sociology, social work, criminology. If your department or journal names a style, always follow it.

Vancouver to ASA: frequently asked questions

How do I convert Vancouver citations to ASA?

Paste your Vancouver reference list into the box above (one reference per line, numbered, or separated by blank lines), check that “From” says Vancouver or Auto-detect and “To” says ASA, then press Convert. You can also paste DOIs, BibTeX or RIS. Copy the result or download it for Word.

How do in-text citations change from Vancouver to ASA?

Vancouver uses a number in round brackets, square brackets or superscript, e.g. (1), in the order sources are first cited. ASA uses author and year, with a page number after a colon, e.g. (Suri and Jack 2016:1290). For the same article and page: Vancouver gives (1), ASA gives (Suri and Jack 2016:1290).

Does the order of my references change in ASA?

Yes. Vancouver: numbered in the order of first citation. ASA: alphabetical by first author’s surname. CiteSwap sorts the converted list for you.

Do titles need different capitalisation in ASA?

Yes. ASA uses title case for article and book titles, so words like “Poverty” and “Gender” are capitalised. CiteSwap applies this automatically.

How are author names written in ASA?

ASA: First author inverted with full names, the rest in normal order. Vancouver: Surname and initials without full stops, e.g. Suri T, Jack W. When a reference is matched in Crossref, CiteSwap uses full first names from the publisher’s record, so it can produce either form.

Is the Vancouver to ASA converter accurate?

Each reference is matched against the Crossref catalogue (over 150 million records) and only accepted automatically when the title, year and first author agree. Anything uncertain is marked “Needs review” so you can pick the right match, and references that aren’t in the catalogue, like websites or local journals, are parsed from your text and marked so you can check them.
