Frequently Asked Questions
What indent styles does the formatter support?
The formatter supports three indent styles: 2 spaces, 4 spaces, and tabs. You can select your preferred style from the dropdown before formatting your code.
Does the formatter execute my JavaScript code?
No, the formatter only restructures the text for readability. It does not execute, evaluate, or run any JavaScript code. Your code is processed purely as text.
Can the formatter handle syntax errors in my code?
The formatter performs basic structural formatting based on braces and brackets. If the code has syntax errors, the output may not be perfectly formatted, but the tool will still attempt to beautify it.
Is my code sent to any server for formatting?
No, all formatting is done entirely in your browser. No code is uploaded to any server, ensuring your source code remains completely private and secure.
How do I copy the formatted code?
After formatting, click the "Copy Result" button to copy the formatted code to your clipboard. You can also manually select and copy text from the output area.
