Convert PDFs into Spreadsheets with AI

Convert PDFs into spreadsheets with AI

Most business data still lives inside PDFs: invoices from suppliers, statements from banks, reports from internal tools, exports from legacy systems. Getting that data into a spreadsheet used to mean either retyping it by hand or wrestling with brittle table-extraction tools. Sehnna's AI PDF to spreadsheet converter replaces both — upload the document, describe the structure you want, and download a clean Excel, CSV, or Google Sheets file in seconds.

How AI-powered extraction works

Sehnna's AI doesn't just OCR your PDF. It reads the document end to end, detects table boundaries, identifies column headers, infers data types (dates, currency, integers, text), and rebuilds the table as a structured spreadsheet. Multi-page tables are stitched into a single sheet. Mixed content (paragraphs between tables) is ignored. The output is a real workbook, not a CSV dump.

Extract, clean, and format in one step

• Extract: detect every table in the document, even across multiple pages.
• Clean: trim whitespace, normalise capitalisation, drop empty rows, fix encoding glitches.
• Format: type columns as dates, currency, percentages, or text so formulas work.
• Restructure: split combined columns, merge duplicates, group by category — all from a prompt.
• Summarise: add totals rows, a summary tab, or a chart in the same conversation.

Export to Excel, CSV, or Google Sheets

Once the spreadsheet looks right, export to whatever format your workflow needs. Sehnna outputs native .xlsx that opens cleanly in Microsoft Excel and Numbers, CSV for data pipelines and BI tools, and the same .xlsx works in Google Sheets via File → Import or by dragging into Drive. No lock-in, no proprietary format.

What this is great for

• Bookkeepers turning supplier invoices into a single expense register.
• Operators extracting bank statements into a categorised cash-flow sheet.
• Sales teams converting quarterly PDF reports into pivot-ready data.
• Recruiters pulling candidate lists out of vendor exports.
• Analysts ingesting legacy reports without rebuilding the source system.

Why a chat-based workflow beats a one-shot converter

Most PDF-to-spreadsheet tools give you one output and walk away. Sehnna treats extraction as a conversation: preview the result, ask for fixes ('split that column', 'reformat dates', 'group by vendor'), and iterate until the spreadsheet looks exactly how you'd build it by hand — without the hours of work.

Sehnna is your AI spreadsheet workspace

Conversion is one piece of the picture. The same AI that turns a PDF into Excel can also create spreadsheets from scratch, generate business templates, improve existing files, and turn raw data into reports. Once your data is in a sheet, you're already in the right place to do more with it.
