Built by a student tired of paying for limits and uploading files to unknown servers. MiToolHub is 100% client-side: your files never leave your browser. Because there's no server cost, everything is free and unlimited. I create tools that save time and help you grow—like our Dummy Data Generator with a "Dirty Data" mode to practice Excel/SQL cleaning. Using AI agents taught me that planning is everything. New tools every week. Fast, clean, distraction-free.
If you're learning Excel, SQL, or Data Analysis, this one's for you!
I've just updated the Dummy Data Generator to become a real practice playground. You can now generate up to 100,000 rows of fake data with a 'Dirty Data' toggle that randomly injects missing values, typos, extra spaces, and case errors. It's perfect for practicing data cleaning in Excel or Sheets without hunting for messy datasets online.
I also added dedicated Business, Marketing, and HR columns (like Revenue, CTR, Salary, Department, etc.) so you can build realistic sample data for dashboards or portfolio projects. Everything stays in your browser—no uploads, no privacy worries.
It's a completely free tool to help you master messy data. If you're a data nerd, give it a try and let me know what other columns or dirty data types you'd like to see! Link: https://mitoolhub.com/en/tools/dummy-data
