Frequently Asked Questions About EXCEL to JSON Conversion
Everything you need to know about formats, privacy, and browser-based file conversion.
How does the Excel to JSON converter map columns?
The first row of your worksheet is treated as object keys, and each subsequent row becomes an object in a JSON array: [{ column1: val1, column2: val2 }].
Can I select which sheet to convert from a multi-sheet workbook?
By default, the first worksheet is parsed. You can specify custom sheet names in the options panel before downloading.
Are numbers, booleans, and dates typed properly in the JSON output?
Yes. Excel numeric and boolean cells remain native JSON numbers and booleans rather than being coerced to strings.
