How to fix your in-text citations in three steps
Paste your text
Body text with its citations, up to 500 words: the literature review with three citation styles in it, the section a co-author drafted, the paragraph the journal flagged.
Pick the target style
APA 7, MLA 9, Chicago author-date or Harvard. Every citation is found, fixed and converted to that style's rules: comma use, and versus ampersand, et al. thresholds, page forms and ordering.
Review each change
Every fix is listed with the original wording, the new form and its reason. A citation missing something the style needs is flagged with what to add, never silently completed.
Why writers fix citations here
Four target styles
APA, MLA, Chicago author-date and Harvard, each applied with its own comma, ampersand, et al. and page rules rather than a one-size template.
Nothing invented
A rule-based gate rejects any output whose citations use a surname or year not present in your text; missing details are flagged, not filled in.
Every fix explained
Each change names its rule, so the pass doubles as a working reference for the style you are converting into.
Prose left alone
Only the citations change. Your sentences, quotations and any reference-list entries come out exactly as you wrote them.
In-text citations: small marks, strict rules, frequent mistakes
In-text citations are the most rule-dense strings in academic writing. APA wants a comma between author and year, Chicago author-date forbids it, and MLA replaces the year with a page. The ampersand is correct inside APA parentheses and wrong in APA narrative citations, wrong everywhere in Harvard. APA abbreviates three authors to et al. from the first citation, Chicago and Harvard wait for four. Multiple works in one parenthesis are ordered alphabetically in APA and separated by semicolons everywhere. No single rule is hard; the density is the problem, and it is why in-text errors survive proofreading that catches everything else.
Mixed styles usually arrive innocently. A paragraph pasted from an earlier paper written for a different journal, a co-author trained on Harvard while the target is APA, a note taken from a source that cited in MLA. The fixer reads each citation, applies the target style's rules, and lists every change with its reason, which makes the review fast: you check a list of citations rather than re-reading the section. The classic mechanical slips, et. al. with the stray period, pg. for p., two adjacent parentheses that should be one citation, are corrected in the same pass.
The rule that matters most is the negative one: nothing gets invented. An in-text citation is a pointer to a real entry in your reference list, so the output is gated by a check that every surname and year in the converted citations already appears in your text, and a citation lacking a detail the target style wants, like the page MLA expects, is flagged with what to add instead of being quietly completed. The reference list itself is the other half of a style switch: the reference format converter rebuilds it entry by entry from real database records, and the AI citation checker verifies that the entries themselves exist before you convert anything.
For building new citations rather than fixing existing ones, the citation generator produces both the reference entry and its matching in-text forms in seven styles, and the DOI to citation converter does the same straight from identifiers. When the whole manuscript needs the pass, the ProofreaderPro editor proofreads complete documents with tracked changes and treats citations as protected content.
Example: four citation problems, fixed for APA 7
A passage with the classic slips: a missing comma, the wrong conjunction and ordering, a broken et al., a nonstandard page abbreviation and two citations that belong together. The APA 7 result in tracked changes, with each fix explained below.
Prior work has shown mixed results (Smith 2020; Jones and Brown 2018). Chen et. al. (2021) reported a similar pattern, and the effect was replicated (Lee, 2022, pg. 143). Earlier reviews agreed (Taylor, 2015)(Nguyen, 2017).

- Comma + order"(Smith 2020; Jones and Brown 2018)" becomes "(Jones & Brown, 2018; Smith, 2020)"APA separates author and year with a comma, uses the ampersand inside parentheses, and orders multiple works alphabetically by first author.
- Et al."et. al." becomes "et al."Et is a complete Latin word and takes no period; only al. is an abbreviation. The narrative citation form is otherwise already correct.
- Page form"pg. 143" becomes "p. 143"APA abbreviates a single page as p. and a range as pp.; pg. is not an APA form.
- Combined"(Taylor, 2015)(Nguyen, 2017)" becomes "(Nguyen, 2017; Taylor, 2015)"Works cited at the same point share one parenthesis, separated by semicolons and ordered alphabetically.
Every author and year in the output already appears in the input; the fixer reorders, punctuates and combines, and flags anything missing rather than inventing it.
