Hey Product Hunt!
I built CleanMyCSV after watching finance teammates spend way too long fixing the same spreadsheet problems every single month—leading zeros vanishing, duplicates hiding, and dates breaking on import.
The thing that bothered me most about existing tools was the upload requirement. You're dealing with vendor invoices, payroll exports, client financial data — and these tools just want you to ship it all to some random server. That never sat right with me.
So everything in CleanMyCSV happens entirely in your browser. Nothing touches a server. Not even temporarily.
Would love honest feedback from anyone in finance, ops, or HR who deals with this regularly. What cleaning problems did I miss? What would make this actually useful for your workflow?
