Your Data Stays on Your Computer
Simple promise: We never see, touch, or store your files. Everything happens right in your browser.
Think of It Like This...
Using XLSX Studio is like doing math on a calculator at your desk. The calculator processes the numbers, but never saves them. When you're done, the numbers disappear. That's exactly how we handle your files.
What Happens to Your File?
You Upload
On Your ComputerYour file loads into your browser (like opening an app on your phone)

We Forget
Gone ForeverEverything erased from memory instantly
Why This Matters
Your file never travels over the internet to our servers. It's like editing a document on Microsoft Word on your laptop - the file stays on your computer the whole time. We can't access it, hackers can't steal it, and there's no database to breach.
How We're Different
Most tools upload your files to the cloud. We don't.
