StatementCSV recognizes Capital One statement PDFs and reads them in your browser. Open the PDF you already downloaded, check every row in an editable table, then export a CSV.
A standard CSV with Date, Description, and Amount columns. It opens in Excel and Google Sheets and imports into QuickBooks and most bookkeeping tools.
You never give StatementCSV your Capital One login, and there's no Plaid connection. The PDF is read in your browser and isn't uploaded, so it isn't stored.
