React Formatter: Format React and JSX Code Online Free
React Formatter uses Prettier to format React and JSX code into a more readable, consistently indented layout. Choose indentation and configure JSX-specific options, including single quotes in JSX and the bracket same line option. For TSX input, the tool uses the TypeScript beautifier. Paste or drop code, format it, then copy the result.
React Formatter is a browser-based tool for formatting React and JSX code with Prettier. It helps make code easier to read and review by applying consistent formatting. You can paste or drop your input, choose indentation, configure JSX-specific options, and copy the formatted result.
The available JSX options include single quotes in JSX and bracket same line. These settings let you adjust how JSX is presented, while the indentation choice controls the visual layout of the output. The formatter also accepts TSX through the TypeScript beautifier, so you can format TypeScript-based JSX input as well.
React and JSX code often combines JavaScript expressions with markup-like syntax, while TSX includes TypeScript syntax alongside JSX. Formatting makes this code easier to scan and can reduce whitespace-only differences in code reviews. Developers may also format a snippet before sharing it in a bug report or check whether input parses cleanly when investigating a problem.
React Formatter runs entirely in your browser. No data is sent to a server, no signup is required, and once the page has loaded, the tool works offline. This keeps the code you format on your own device while you use the formatter.
The tool is useful for developers and DevOps engineers who review React code, work with JSX or TSX, prepare code snippets, or want consistent indentation. Whether you are checking code written by someone else or tidying a generated file before a commit, the configurable formatting options help make the result easier to work with.
Step 1: Paste or drop your React or JSX code into the formatter. For TypeScript-based JSX, you can provide TSX input.
Step 2: Choose the indentation you want for the formatted output. Consistent indentation can make code easier to review.
Step 3: Set the JSX options you need, including single quotes in JSX and bracket same line.
Step 4: Format the code and review the result. The formatter can also help you check whether the input parses cleanly.
Step 5: Copy the formatted output and use it in your project, code review, or bug report.
Use case: Make an unreadable, machine-generated React file easier to review before you commit it.
Use case: Check a React document you did not write against the formatting conventions you need to follow.
Use case: Produce consistently indented output so a diff highlights code changes instead of whitespace noise.
Use case: Format a snippet before pasting it into a bug report or code review.
Use case: Check whether React input parses cleanly and identify the line where an issue occurs.
Use case: Format a TSX component when you want readable output for TypeScript-based React code.
Use case: Apply the single quotes in JSX or bracket same line option when you need JSX output to follow a chosen style.
