Drop your Amex 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.
Amex's own download options (PDF, CSV, OFX, QFX) cover the basics but don't always include JSON. Amex statements include a separate 'Payments and Credits' section and a 'New Charges' section. The converter merges them into a single sorted transaction list, which is what bookkeeping tools expect.
