Frequently Asked Questions
What Excel formats are supported?
The converter supports .xlsx (Excel 2007+) and .xls (legacy Excel) formats. For best results, use .xlsx files.
Does the first row need to be headers?
Yes, the first row is treated as column headers which become the JSON object keys. Each subsequent row becomes an object.
What about multiple sheets?
Currently, only the first sheet is converted. If you need to convert multiple sheets, export them separately.
Are formulas evaluated?
Yes, formula results are included in the JSON output, not the formulas themselves.
