About Excel → JSON
The Excel to JSON converter securely parses Excel spreadsheets (.xlsx, .xls) and transforms them into an array of JSON objects. It extracts rows and column headers automatically, making it incredibly useful for data migration tasks.
How to Use
Real-World Examples
Migrating Client Data
Convert a provided client Excel spreadsheet into a JSON array that can be easily seeded into your application's database.
Best Practices
- Ensure the first row of your Excel sheet contains the column names (headers).
- Clean up any empty rows or trailing formatting in Excel before converting to avoid null or empty objects in your JSON.
Pro Tips
Only the first active sheet in your Excel workbook is converted. If you have multiple sheets, save them as separate files.
