FEC Viewer

A desktop app for exploring .fec files, the electronic filings committees submit to the Federal Election Commission. Open a filing to browse its cover page, schedules and every itemized record.

FEC Viewer showing a filing's Schedule A contributions in a table, with a sidebar of schedules and a detail panel for the selected record.

The browser demo runs the same native UI compiled to WebAssembly. Drop a .fec file on it; it's parsed entirely in your browser and never uploaded anywhere.
