  • Clean up copied log lines or exported data before pasting into tickets, docs, or pull requests.

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.
