Frequently asked questions
Is this a real Excel file or a CSV?+
A real .xlsx workbook: numbers are numbers, true/false are booleans, the header row is bold and frozen, and columns are sized to fit.
What happens to nested JSON?+
Nested fields become columns like customer.name. Arrays can be joined into a cell, spread into numbered columns, or expanded into one row per item.
Will long IDs get rounded?+
No. Numbers longer than 15 digits (which Excel would round) are written as text, so IDs and card-like numbers stay exact.
Can I paste straight into Google Sheets?+
Yes — use “Copy for Sheets” and paste into any spreadsheet. Columns line up automatically.
Is my data uploaded?+
No. The workbook is created in your browser.
