How to Convert Smart Quotes to Straight Quotes (And Vice Versa) Guide (2026)
Paste text from Word into a code editor and your quotation marks may quietly break things — Word turns straight quotes (”) into curly “smart” ones (”) that most programming languages don’t recognise as string delimiters. The Smart Quotes Converter swaps between curly and straight quotes (and apostrophes) in both directions, so you can clean code-bound text or add typographic polish to prose.
The Difference Between Smart and Straight Quotes
Smart quotes — also called curly quotes or typographer’s quotes — are directional quotation marks that curve toward the text they enclose. The opening double quote (”) curves left, while the closing double quote (”) curves right. Single smart quotes follow the same directional pattern (“opening” and “closing”). Word processors like Microsoft Word, Google Docs, and Apple Pages automatically convert straight quotes to smart quotes by default.
Straight quotes are the neutral vertical marks found on keyboards (” and ’). They do not have directional differences and are used in programming, HTML, JSON, markdown, database entries, and plain text files. Straight quotes are always preferred in code because smart quotes can cause syntax errors, broken strings, and unexpected behavior in interpreted languages.
Why Convert Between Quote Styles
Developers need to replace smart quotes with straight quotes when pasting text from word processors into code. Smart quotes in source code cause syntax errors, string breakage, and database insertion failures. Writers converting code snippets for documentation often need to add smart quotes for proper typographic formatting between regular prose and inline code. Content managers processing user-submitted text may need to normalize quote styles for consistency across the site. Publishers and typesetters use smart quotes for professional-looking output in books, articles, and long-form content.

FAQ
Why do smart quotes cause problems in code?
Most programming languages, markup languages, and databases treat ” and ’ as string delimiters. Smart quotes are different Unicode characters that are not recognized as string boundaries, so they appear inside strings or cause parsing errors. JavaScript, Python, PHP, HTML, JSON, and YAML all require straight quotes for string syntax.
Does the tool handle mixed quotes?
Yes. The tool scans each quote character individually and converts it appropriately. Mixed text containing both smart and straight quotes is handled correctly in both conversion directions.
What about prime marks (feet and inches)?
Prime marks (′ and ″) are distinct from smart quotes. Our tool focuses on quotation marks (’ and ” variants). If your text uses prime marks for measurements, those are preserved unless the tool is explicitly set to handle them.
Can I use this for French guillemets?
The tool handles the primary quotation marks found in English text. Guillemets (« ») used in French and other European languages are not converted by default but may be supported in an extended mode.
Does the conversion affect apostrophes?
Yes. Apostrophes are represented by the same character as single closing quotes (U+2019 for smart, U+0027 for straight). The tool converts apostrophes along with other single quotes, which is the correct behavior for text normalization.
Is the conversion lossy?
Converting smart to straight is lossless — each smart quote maps to a straight quote. Converting straight to smart can be ambiguous because straight quotes do not encode direction. The tool uses heuristic rules (preceding character analysis, word boundaries) to determine opening vs. closing direction.
