FAQ
Do I need any software to view the dashboard?
No — that's the whole point! It's a single HTML file that opens in any browser (Chrome, Edge, Safari). No licenses, no accounts, works offline.
Can I update the dashboard myself when I get new data?
Yes. Standard and Premium include a refresh script: put your new Excel/CSV file in the folder, run one command, done. No coding needed.
Can I share the dashboard with my team?
Yes — just send them the HTML file, or put it on a shared drive. Everyone can open it, no accounts needed.
Is my data safe?
Completely. The dashboard runs 100% locally in your browser — your data is embedded in the file and never sent anywhere. I delete your files after delivery.
My data is messy / spread across many files. Is that a problem?
Not at all — cleaning and merging is included (Standard and up). Messy data is my specialty.
