Turn any spreadsheet into a beautiful chart. Import CSV or Excel files, build custom visualizations, and save them locally. No cloud, no account.

About Chartform

Chartform turns your spreadsheet data into polished, shareable charts, entirely on your iPhone. Import a CSV or Excel file from anywhere on your device, pick your chart type, map your columns, and you have a visualization in seconds.

Every chart you create is saved to your local library using SwiftData. Browse your collection, regenerate charts from the same dataset in different styles, and export any visualization as a high-resolution image whenever you need it.

No account. No subscription. No cloud. Chartform is built for people who work with data on the go and need a fast, private way to turn numbers into something they can actually show someone.

Privacy note

Chartform stores everything locally on your device. Imported files and generated charts never leave your phone. We collect no data of any kind.
