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.
Mixing date-only and datetime fields when the UI expects calendar dates.
Fix: Match the input style shown on the tool. Date-only mode counts calendar days, not clock times.
Picking the wrong unit category (weight versus volume, miles versus km).
Fix: Confirm unit labels on the tool match the values you entered before you copy the result.
