    Invoice Data Extractor

    Example session with this skill installed

    Log all the receipts in the inputs/invoices folder into my ledger. Flag anything that looks like a duplicate or has blurry text.

    • Read your context and instructions
    • Compiled the invoice data extractor
    • Generated the data export

    I have processed the invoices in inputs/invoices/. I scanned 4 files: 3 were successfully added to the ledger, and 1 was skipped as a duplicate.

    • New Records: 2
    • Total Value Added: $1,268.50 USD
    • Ledger Path: outputs/financial-ledger.csv

    Next steps

    1. Open outputs/financial-ledger.csv to manually reconcile the $2.00 discrepancy in the Staples receipt.
    2. The folder contained a .heic file which was skipped; convert this to JPG if you need it processed.
    3. Run the command with --append-conflicts if you want to force the Staples entry into the ledger anyway.

    About this skill

    The problem

    Manual entry of invoice data into spreadsheets is slow and prone to transcription errors. Typos, missing tax lines, and double-counted expenses often corrupt financial records during hand-coding.

    What it does

    • Scans local directories for PDFs, images, and scans to extract vendor names, dates, and totals.
    • Itemizes line items including shipping, tax, and discounts into structured categories.
    • Calculates stable IDs to prevent duplicate entries when re-scanning the same folder.
    • Validates that line items sum to the invoice total before updating the ledger.
    • Generates a CSV financial ledger with formula injection protection for Excel and Sheets.

    Frameworks & tools

    Python for data processing, Claude Vision for OCR and handwriting analysis, and layout-preserved text extraction for digital PDFs.

    Why this beats prompting it yourself

    Standard prompting often fails at mathematical reconciliation and duplicate detection. This skill uses a dedicated script to verify totals and ensure append-only safety, preventing the agent from hallucinating figures or corrupting existing ledger files.

    Use cases

    • Processing a month of mixed receipts and digital invoices for tax preparation.
    • Reconciling expense folders where vendor formats change constantly.
    • Migrating paper-based bookkeeping into a machine-readable CSV format.

    Known limitations

    Cannot process password-protected PDFs without prior decryption. Does not support multi-currency invoices within a single document.
