How do you use AI to convert invoices to JSON?
By Tim White · Last updated
To convert invoices to JSON with AI: send each invoice to the model, which extracts vendor, invoice number, dates, tax, totals, and line items into a structured object, then export or receive that JSON. With InvoiceJet, JSON is a native export, every field carries a confidence level and its source, and you can also POST an invoice to the API and get the JSON back inline. JSON is the format to reach for when the data feeds another system rather than a spreadsheet.
1. Send the invoice to the AI
Upload it, forward it by email, or POST it to the API. However it arrives, the model treats it the same: read the document, find the fields.
2. Get a structured object back
Extraction returns a JSON object with the vendor, invoice number, dates, currency, tax, totals, and an array of line items. With InvoiceJet each value also carries a confidence level and the spot on the document it came from, so your code can decide what to auto-post and what to route for review.
3. Export it, or receive it live
Export JSON from the app, or skip the manual step: a signed webhook fires as each invoice completes, and the REST API returns the JSON inline when you send an invoice with wait enabled. See the API docs for the exact schema.
4. Feed it downstream
Drop the JSON into a database, map it to your accounting system, or drive a custom workflow. Because the fields are verified before they arrive, you are integrating clean data, not parsing a best guess.
A worked example
Say a signed webhook delivers a completed invoice. Your code walks the fields and reads the confidence on each. If vendor, total, tax, and every line item come back high confidence, you post it straight to your ledger. If the tax field is uncertain, you route just that invoice to a person and let the rest flow through. Per-field confidence is what makes this work: you automate the invoices that are safe and hold back only the ones that are not.
Common questions
What does the JSON include?
Vendor, invoice number, issue and due dates, currency, tax, totals, and line items, plus a confidence level per field and its source location on the document.
Can I get the JSON automatically for every invoice?
Yes. Signed webhooks push it as invoices complete, and the REST API returns it inline or lets you pull it on your own schedule. A Node SDK, CLI, and MCP server are coming soon.
Is XML available as well as JSON?
No. Native exports are CSV and JSON, with no XML export. JSON is the structured format to reach for when the data feeds another system.
Does each invoice's JSON include one object per line item?
Yes. Line items come back as an array inside each invoice object, so you can read totals at the invoice level and drill into individual lines for spend analysis.
