👋 Hi Product Hunt! I am Nirob, the maker of Spreadsheet Fixer.

Working with messy Excel and CSV files is a daily nightmare for many of us. But as a developer and data enthusiast, I realized a bigger problem: Privacy.

Uploading sensitive client data, financial records, or HR spreadsheets to random 3rd-party cloud websites is extremely risky.

So, I built Spreadsheet Fixer—an enterprise-grade cleaning suite that runs 100% offline in your browser's RAM. Zero cloud uploads. Zero data tracking.

✨ Core Features:

- 1-Click duplicate row elimination (Zero collision algorithm).

- Prune completely empty rows and columns.

- Format mixed dates and trim extra spaces.

- Process everything locally on your device instantly.

It's completely FREE. I built this to solve my own problems, and I hope it saves you hours of manual work too! I would love to hear your feedback, and I am here to answer any questions! ❤️
