The spreadsheet problem
You ask someone to fill out a spreadsheet. What happens next?
"Hi, can you re-send that spreadsheet template?
Wait, the columns were different in the other version...
Can you fix row 5? The date format is wrong.
Is this email with the attachment maybe the right one?"
"Here's the form. Fill it out in your browser.
Validation tells you if something's wrong.
When you're done, download your CSV.
That's it."
Import Builder's answer
Build the structure once. Your users fill it out in a familiar spreadsheet interface. Validation happens automatically. They download clean CSV.
Try it yourself. No signup required.
This is a real Import Builder form. Enter a few rows, try the validation, and download the CSV. This is exactly what your users will see.
