TypeScript Beautifier: Format Code Online in Your Browser
TypeScript Beautifier uses Prettier to turn TypeScript input into consistently formatted code. Paste or drop a snippet, then choose indentation and adjust print width, semicolons, quotes, and trailing commas to match your preferred style. Review the formatted result and copy it for your editor, code review, bug report, or other development workflow. It can also help reveal where input does not parse.
TypeScript Beautifier is an online TypeScript formatter that uses Prettier to make source code easier to read and review. Paste or drop TypeScript into the tool, choose indentation, and generate a consistently formatted result. It is useful when you need to format TypeScript online without manually adjusting whitespace and punctuation.
Formatting behavior is adjustable: set indentation and print width, and configure semicolons, quotes, and trailing commas. These options let you shape the result to match the style you need. After formatting, copy the output into your editor, review, or report. The tool can also help identify the line where input fails to parse.
TypeScript source files contain code, while formatting determines how that code is laid out. Consistent indentation, line width, semicolons, quotes, and trailing commas can make machine-generated files or unfamiliar snippets easier to inspect and reduce whitespace-only noise in diffs. Use the formatter before committing, sharing a snippet, or reviewing code when a clearer layout would help.
TypeScript Beautifier runs entirely in your browser: input is processed on your device and is not uploaded, stored, or sent to a server. No signup is required, and after the page loads it continues to work offline. This makes it a practical formatting tool for developers and DevOps engineers who want to improve code readability while keeping their source text local.
Step 1: Paste or drop your TypeScript into the tool. Use a snippet or a complete TypeScript document as input.
Step 2: Choose the indentation setting you want. Consistent indentation can make the formatted code easier to scan and compare.
Step 3: Adjust the available formatting options, including print width, semicolons, quotes, and trailing commas. These settings let you shape the output to suit your preferred style.
Step 4: Review the formatted result and copy it. If the input does not parse, use the reported line to locate the issue in your source.
Use case: Make an unreadable, machine-generated TypeScript file easier to review before you commit it. Consistent formatting helps you focus on the code rather than its layout.
Use case: Check a TypeScript document you did not write against the formatting style you need to follow. Adjust indentation and the other available options before reviewing the result.
Use case: Produce consistently indented output so a diff highlights code changes instead of whitespace noise. This is useful when preparing TypeScript files for a code review.
Use case: Format a snippet before pasting it into a bug report or code review. Clear layout makes the example easier for others to read.
Use case: Check whether TypeScript input parses and find the line where it does not. This can help you narrow down a syntax issue before continuing your work.
Use case: Standardize the appearance of a TypeScript snippet before sharing it with a teammate. Set options such as quotes and semicolons to get output that is easier to compare.
Use case: Tidy a small piece of TypeScript before adding it to project notes or technical documentation. Readable formatting makes code examples easier to follow.
