Troubleshooting Common Issues
Invalid JSON Error
Problem: The converter shows a syntax error when you paste JSON.
Fix: Check for missing commas, unmatched brackets, trailing commas, and ensure property names use double quotes.
Numbers Displayed as Text
Problem: Excel shows numbers with leading zeros (e.g., "000123") as text.
Fix: Select cells → Data → Text to Columns → Finish, or use formula =VALUE(A1).
Nested Arrays Show as [Object]
Problem: Nested arrays or objects display as "[Object]" in Excel.
Fix: Use the "Flatten Nested Data" option. Arrays expand to multiple rows, objects flatten with dot notation.
Special Characters Look Wrong
Problem: Emojis, accents, or symbols display incorrectly.
Fix: Open in Excel via File → Open (not double-click) and select UTF-8, or use Google Sheets.
