Export Debugging tips

🐛

When your "Export to CSV" button outputs something weird, drop the file here to see exactly what shape Excel will see.

💡

Common issue: quoted fields with embedded commas. The parser handles RFC 4180 quoting — if it looks correct here, Excel will too.

🎯

Counts in the file chip show row count and column count — verify they match what your backend should produce.

📋

For large exports (10K+ rows), the table scrolls smoothly. Sort and filter to find specific issues quickly.
