What differs for JSON API

For statements delivered as XLSX, templates are built in Word (3) and HTML (1). All 4 read JSON sent to an API without a Zapier, Make or n8n step in between. Of these, 2 have a free tier.

Besides XLSX, these tools for statements also write PDF (4), DOCX (3) and PPTX (2). Your own code decides when to call the API, so a document can be built on any event. Published starting prices run from $15 to $28 a month, the top end from Carbone. Prices were checked on 20 Oct 2026.
