Common mistakes and fixes
Pasting API keys or 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.
