How to Reformat a Reference List for a Different Journal

A journal sends back a manuscript with a one-line note inviting a resubmission to its sister journal instead. The invitation sounds like good news until the formatting requirements arrive: the sister journal runs a numbered reference style, and the rejected manuscript was written entirely in APA.

How to reformat a reference list for a different journal is a bigger question than it looks, because the reference list is not the only thing that changes. Switching from an author-date style to a numbered one, or the reverse, moves the citation markers themselves, reorders the list from alphabetical order to the order sources first appear, and touches every cross-reference sitting in the body text. A find-and-replace pass on the bibliography alone leaves a manuscript half-converted.

TextPulse's guide to referencing styles lays out the three underlying systems, author-date, numbered and notes, that every named style belongs to. Reformatting for a new journal is the practical version of moving between those systems, and it is worth knowing which two are actually involved before opening a single reference.

How to Reformat a Reference List for a Different Journal: The Real Task

A rejection letter or a new journal's instructions for authors names a needed style, and that name settles which family the manuscript needs to move into. Moving from an author-date manuscript to a numbered journal, or vice versa, means doing three distinct things: switching all the in-text citation markers, sorting the reference list itself, and altering all the cross-references in the running text pointing at a specific source. Doing one out of those three leaves a manuscript that only looks reformatted.

• Change the shape of every in-text citation marker, not only the ones on the first page.
• Reorder the reference list itself, from alphabetical order to citation order, or the reverse.
• Update every cross-reference in the body text that points at a specific numbered or named source.

Why the In-Text Citations Change Shape Too

An author-date citation sits inside the sentence as a name and a year, doing real work: a reader can judge how recent a finding is without leaving the page. A numbered citation replaces all of that with a digit that points elsewhere, keeping the sentence compact no matter how many sources back it. Moving a manuscript from one family to the other means every single one of those markers is rebuilt, not edited in place, because the two markers carry different information and sit differently in the sentence.

A sentence that reads 'Chen (2023) found a similar effect in a smaller cohort' under an author-date style has to become something like 'a similar effect was found in a smaller cohort [7]' under a numbered one, or the name has to move out of the sentence entirely so the number can take its place. That is a rewrite, not a formatting pass, and it is exactly the gap an in-text citation fixer is built to close once the reference list itself is already sorted.

Reordering the List: Alphabetical to Citation Order and Back

Author-date reference lists sort alphabetically by surname, so a reader can scan straight to a name they already have in mind. Numbered reference lists sort by citation order instead: source one is whichever source the text cites first, source two is whichever it cites second, regardless of either author's surname. Moving a manuscript between the two families means the list itself is rebuilt in a different order, not just renumbered in place.

Inserting or deleting a single source partway through a numbered list shifts every citation number after it, in the list and in the body text both, and a manuscript with forty or fifty references gives that mistake plenty of places to hide. This is where a manuscript is most likely to end up silently wrong.

	Author-date style	Numbered style
In-text marker	A name and year, such as (Chen, 2023)	A digit or bracketed number, such as [7]
Reference list order	Alphabetical by surname	Order of first appearance in the text
Effect of adding one source	No renumbering needed elsewhere	Every later number shifts by one
Repeat citation of the same source	Same name and year each time	Same number reused each time

Reference Manager or By Hand: What Each Approach Actually Costs

Reference management software built around the Citation Style Language format, an open standard used by tools such as Zotero and Mendeley, can reformat both the in-text markers and the reference list in one pass, provided the citations were inserted as live fields through the software's own plugin rather than typed as flat text. Switching the selected style from an author-date option to a numbered one, or the reverse, triggers an automatic rebuild of the whole document's citations at once, drawing on a shared repository of more than ten thousand journal-specific style files.

But there're limits to convenience. The reference management tool EndNote saves its own citations styles in a proprietary format that isn't interchangeable with the open Citation Style Language files used by Zotero and Mendeley. It may be easy to take a style file you have built for Zotero or Mendeley and re-use it within your paper in those systems. But if you're inheriting a manuscript as flat, typed text (not as live citation fields), you get none of this automation regardless of which system you're using because the software has nothing in the document it recognizes as a citation.

For a manuscript with no live citation fields to rebuild, working through the reference list entry by entry with a reference format converter is faster and more consistent than retyping each one from memory against a new style guide.

Doing the whole job by hand is still common, particularly for a short manuscript or a journal whose house style does not match any of the built-in options a reference manager offers. Hand reformatting rarely fails outright. It succeeds everywhere a writer remembered to check and fails exactly where they did not, which is a harder mistake to catch than an obvious one.

The Specific Things That Break Silently

Some failures show up immediately: a citation with no matching reference, a reference nobody cites. Others do not, and they are the ones worth checking for deliberately before a manuscript goes back out.

• A cross-reference inside the text, such as a mention of a specific numbered source in a table caption or a footnote, that was never updated when the list around it was renumbered.
• A citation repeated later in the same paragraph that keeps its old author-date form after the rest of the paragraph was converted to numbers.
• A reference that still carries formatting from the old style, italics, quotation marks or a journal name spelled out in full, that the new style does not use.
• A source cited only in a table or a figure caption, easy to miss because both automated tools and manual checklists tend to focus on the running text first.

Before You Resubmit: A Last Check

Reading the reformatted manuscript once from the first citation to the last, in order, catches most of what automation and a careful first pass both miss, because it is the only check that follows the numbers or the names in the exact sequence a reviewer will.

An annotated bibliography is a different document from a literature review, and the distinction is drawn separately. Which styles UK universities actually set is its own survey.

The reference list is a mechanical problem with a mechanical fix, whichever direction the conversion runs. A citation generator that pulls each entry from a real publisher record removes most of the risk of a stray old-style detail surviving into the new one, before a reader ever gets far enough to notice the punctuation.
