Is my TypeScript code sent to a server?

No. Formatting runs entirely in your browser using a JavaScript library loaded from a CDN. Your code is never uploaded or transmitted anywhere.

Does this support TSX (TypeScript with JSX)?

The formatter targets plain TypeScript syntax: types, interfaces, generics, classes, and modules. Files with JSX markup may not format perfectly.

The tool shows an inline error message describing the parse problem instead of crashing, so you can fix the offending line and try again.

Yes. Toggle the quote style option before formatting, and every string in the output uses your chosen quote character.

If the "Add semicolons" option is checked, missing statement-ending semicolons are inserted. Uncheck it to format without semicolons.
