Drop your Capital One statement PDF and download a clean .json file in under 30 seconds. Runs entirely in your browser — your statement never leaves your device.
Every transaction comes back as a clean JSON object with date, description, amount, currency, and balance fields. Drop it into pandas, feed it to an LLM for categorisation, or POST it to your own backend.
Capital One's own download options (PDF, CSV (Venture/Quicksilver), OFX) cover the basics but don't always include JSON. Capital One's PDF layout puts the running balance on the right edge and uses a consistent date format, which our parser normalizes to YYYY-MM-DD on export so the data sorts correctly in Excel and Google Sheets.
