Drop in any Excel file. Chartberry reads it, finds what matters, and builds an interactive dashboard — every total checked against your source before you ever see it.
Any layout works — financial statements, flat exports, pivot-style reports. Chartberry figures out the structure itself.
Claude extracts your data in a secure, air-gapped sandbox, then re-computes every total against your file. If it doesn't tie out, it doesn't ship.
An interactive dashboard — KPIs, charts, filters — in a single HTML file you can email, share by link, or keep private.
Uploads exist only for the seconds it takes to generate. Analysis runs in an isolated sandbox with no network access. We keep the dashboard — never your source data.
