JSX Formatter: Format JSX Code for Clearer Reviews
The JSX Formatter formats JSX with Prettier to make code easier to read and review. Choose indentation and configure JSX-specific options, including single quotes in JSX and whether brackets stay on the same line. Paste or drop your JSX, then copy the formatted output. The tool also helps you check whether input parses cleanly and locate a problematic line.
The JSX Formatter is a browser-based tool for formatting JSX with Prettier. It helps turn hard-to-read JSX into consistently arranged code that is easier to inspect, share, and review. Paste or drop your input to get started, then copy the formatted result where you need it.
Choose the indentation and configure JSX-specific options, including single quotes in JSX and whether brackets stay on the same line. These settings let you adjust the formatted output to match the conventions you are working with. The tool can also help you check whether the input parses cleanly and locate the line associated with a parsing problem.
JSX is a syntax used to describe UI structures in JavaScript, while formatting changes how that code is laid out for reading. A JSX Formatter is useful when generated or unfamiliar code is difficult to scan, or when inconsistent whitespace makes a review harder. Formatting can make diffs clearer by reducing layout noise, without changing the goal of the code being reviewed.
The formatter runs entirely in your browser: your input is processed on your device, and no data is sent to a server. It is free, requires no signup, and works offline once the page has loaded. This makes it convenient for formatting JSX without uploading your code.
Developers at any experience level can use the JSX Formatter to prepare code for commits, reviews, bug reports, or collaboration. DevOps engineers and other technical teams can also use it when they need readable JSX examples while investigating or documenting a change.
Step 1: Paste or drop your JSX into the formatter. Use the JSX snippet or document you want to make easier to read.
Step 2: Choose the indentation you want for the output. Consistent indentation can make code reviews and diffs easier to follow.
Step 3: Set the JSX-specific options, including single quotes in JSX and whether brackets stay on the same line.
Step 4: Review the formatted output and check whether the input parses cleanly. If it does not, use the reported line to help locate the issue.
Step 5: Copy the formatted JSX for your editor, commit, code review, or bug report.
Use case: Make an unreadable, machine-generated JSX file easier to review before you commit it, so the code is more approachable for your team.
Use case: Check JSX written by someone else against the formatting conventions you need to follow, using the available indentation and JSX-specific options.
Use case: Create consistently indented output so a diff is easier to scan for meaningful code changes instead of whitespace differences.
Use case: Format a JSX snippet before adding it to a bug report or code review, making the example easier for others to read.
Use case: Check whether a JSX input parses cleanly and use the indicated line to help find a syntax problem.
Use case: Tidy a JSX example copied from documentation or a discussion before using it in your project.
Use case: Apply consistent formatting to JSX snippets you share with teammates, helping everyone focus on the code rather than its layout.
