Frequently Asked Questions
How to convert from CSV to Excel?
All you need to do is drag your CSV file into the upload area above and click the Convert button. The process happens locally in your browser and completes in seconds. Then you can download the converted file to your device.
Are my files private when uploaded to the converter?
Yes, absolutely. PRIZMA operates with a zero-server architecture. This means your uploaded files are never transferred to any server; the entire process happens in your own device's browser and memory. Therefore, your files are 100% secure and private.
Do I have to pay for this conversion process?
No, all conversion tools on our platform are completely free and can be used unlimitedly without requiring any registration or membership.
Do I need to install any software?
No installation is required. PRIZMA works entirely inside your web browser (Chrome, Firefox, Edge, Safari), on desktop or mobile, with no extensions or apps to download.
Does converting CSV to Excel reduce quality?
It depends on the formats and settings you choose. Some conversions (like PNG to JPG) can involve quality trade-offs, which you can control with the quality/bitrate options on this page. Lossless conversions between compatible formats keep full quality.
