What openstan does

  • Import bank statement PDFs from any supported bank — one file at a time or whole folders at once.
  • Review import results: successful statements are committed to your project database; statements that need attention are highlighted with full debug output and the original PDF side by side.
  • Summarise your project: transaction counts, account breakdowns, and automatic detection of statement coverage gaps (missing months flagged clearly).
  • Export to Excel, CSV, or JSON — either as a flat transactions table or a full star-schema dataset (accounts, calendar, statements, transactions, balances, gaps).
  • Build reports with a no-code report builder: filter, group, and aggregate your transactions, save named configurations, and export results.
  • Advanced export — spec-driven custom exports via TOML files with per-account and date-range filtering.

Privacy

openstan makes one outbound network call: a silent version check on startup. No statement data, no telemetry, no analytics, no account registration. See the full Privacy Policy.

Your bank statements are sensitive. They stay on your machine.
