Extract Invoices and Build Accounts Payable Spreadsheet

Accounts payable teams receive PDF invoices from multiple vendors and need to log them into a spreadsheet for the approval workflow. This recipe extracts structured data from all invoices in a single call, then feeds the results directly into an XLSX tracker with one row per invoice.

APIs Used

Document Extraction (1 credit per page), Sheet Generation (1 credits/request)

Prerequisites

You need an Iteration Layer API key. Get one at platform.iterationlayer.com during the 7-day trial.

For full integration guidance (SDKs, auth, MCP, error handling), see the Iteration Layer Integration Guide.

Extract invoice data from the files at [file URL 1], [file URL 2], and [file URL 3], then generate an accounts payable spreadsheet. Use the extract_document tool with these fields:

- invoices (ARRAY): One entry per invoice file, each with:
  - vendor_name (TEXT): Vendor or supplier name
  - invoice_number (TEXT): Invoice reference number
  - invoice_date (DATE): Invoice issue date
  - due_date (DATE): Payment due date
  - total_amount (CURRENCY_AMOUNT): Total invoice amount
  - currency (CURRENCY_CODE): Invoice currency

Then use the generate_sheet tool to create an XLSX accounts payable tracker with the extracted rows.

설치

명령으로 설치

npx skills add https://github.com/iterationlayer/skills --skill extract-invoices-to-spreadsheet

터미널에 붙여 넣고 실행합니다(Node.js 필요). Claude Code, Codex 등 설치할 에이전트를 고를 수 있습니다.

에이전트에게 부탁하기

다음 Agent Skill을 설치해 주세요.
https://github.com/iterationlayer/skills/tree/main/skills/extract-invoices-to-spreadsheet

먼저 SKILL.md와 첨부 파일의 내용을 확인해 수상한 처리(외부 전송, 인증 정보 읽기 등)가 없는지 확인한 뒤 Claude Code는 ~/.claude/skills/extract-invoices-to-spreadsheet/, Codex는 ~/.agents/skills/extract-invoices-to-spreadsheet/ 에 배치해 주세요.

이 문장을 그대로 Claude Code나 Codex에 보내면 내용을 확인한 뒤 설치해 줍니다.
