Common mistakes and fixes

• Pasting production secrets, tokens, or personal data into any browser tool.

  Fix: Use redacted samples in development. Client-side processing still leaves data in browser memory and history.

• Assuming formatted output is also valid for every downstream consumer.

  Fix: Run the dedicated syntax checker when validation matters. Formatting and validation answer different questions.

• Processing huge files at once on a slow device.

  Fix: Start with a small excerpt to confirm the output shape, then paste larger sections in chunks if needed.

• Trying to format text that is not valid for the selected language.

  Fix: Fix parse errors shown in the output, or use the matching validator first.
