Harvard to ASA converter

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

Paste references written in Harvard and get them back in ASA, ready to copy into Word or Google Docs. The main changes: your “Reference list” list becomes “References”, titles switch to title case and author names are written as in ASA (first author inverted with full names, the rest in normal order). 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.

Harvard is more common in business, economics, the social sciences, while ASA is usual in sociology, social work, criminology. If your department or journal names a style, always follow it.

Harvard to ASA: frequently asked questions

How do I convert Harvard citations to ASA?

Paste your Harvard reference list into the box above (one reference per line, numbered, or separated by blank lines), check that “From” says Harvard 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 Harvard to ASA?

Harvard uses author and year in parentheses, e.g. (Suri and Jack, 2016). 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: Harvard gives (Suri and Jack, 2016, p. 1290), ASA gives (Suri and Jack 2016:1290).

What is the reference list called in ASA?

In Harvard the list is headed “Reference list”; in ASA it is “References”. Change the heading when you paste the converted list into your document.

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. Harvard: Surname and initials, joined with “and”, e.g. Suri, T. and 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 Harvard 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.
