Stop copying invoices into spreadsheets.
Harold converts supplier invoice PDFs into clean, validated Excel exports automatically — including line items, totals, VAT, and supplier data. Train once per supplier and the pipeline runs forever.
Start free — no card requiredPDF to Excel — the right way
Most PDF-to-Excel tools do character conversion. They turn pixels into text and hand you a messy spreadsheet that still needs manual cleanup. Harold is different — it uses AI extraction trained specifically on your supplier invoice formats, validates the output, and gives you a spreadsheet that's actually ready to use.
Header and line item data in one export
Harold extracts both the document-level data (supplier name, invoice number, date, totals, VAT) and the line item table (product codes, descriptions, quantities, unit prices, line totals) into a single structured spreadsheet — ready to import or analyse without reformatting.
One template per supplier, not per invoice
Most PDF-to-Excel tools require you to configure extraction rules for each invoice you process. Harold learns your supplier once from a handful of examples and then handles every future invoice from that supplier automatically — no repeat configuration.
Validation before export
Harold checks extracted data before it lands in your spreadsheet. Do the line totals add up? Is the VAT figure correct? Are required fields present? Flagged documents go to a review queue rather than exporting with silent errors.
Export on demand or via Zapier
Export any processed run as CSV or Excel from the Harold interface. Or connect via Zapier to push clean structured data automatically to Google Sheets, Excel Online, Airtable, or any other destination — without manual downloading and uploading.
What a Harold Excel export contains
Every export includes a header row with document-level fields and a line items section with full row-by-row data.
