You've built a spreadsheet template. Maybe it's an inventory tracker, a customer list, or a sales report mockup. Now you need it to look real — filled with realistic names, dates, prices, and IDs — so you can test formulas, build a demo, or show a client what the finished product will look like.
The usual options aren't great:
Typing fake rows by hand (slow, repetitive, and always ends up looking like "John Doe" fifty times)
Copying real customer data into a spreadsheet (a compliance headache, and overkill for a mockup)
Using a generic "lorem ipsum" data generator that has no idea what an "order date" or "SKU" column is supposed to contain
