AxonSheet: AI bulk automation & PDF extraction for Microsoft Excel

Hey Product Hunt community! 👋 Like many of you, I've spent countless late nights wrestling with messy spreadsheets—manually copy-pasting customer data, extracting line items from PDF invoices, and hunting down missing company information line by line in Microsoft Excel. When AI arrived, we expected spreadsheet tools to solve this, but existing options had major dealbreakers: 1. They lock you into expensive $20–$30/month subscriptions. 2. They slap strict monthly token caps on your usage. 3. Worst of all, they route your sensitive corporate spreadsheets through third-party cloud servers. That’s why we built AxonSheet: a native Excel add-in designed for power users who care about data privacy and speed. ✨ What makes AxonSheet unique: • 100% Client-Side BYOK: Connect your own OpenAI, Google Gemini, OpenRouter, or local Ollama API keys. Your data never touches our servers. • Bulk Rows Engine: Run custom prompts, translations, and formulas across thousands of rows in seconds. • Document & PDF Parser: Drop PDFs, DOCX, or CSVs directly into the Excel taskpane to generate clean tables. • Autonomous Deep Research: Enrich rows with live web information and auditable source URLs. • Native Formula Auditing: Scan for math errors and attach native Excel comment callouts automatically. We’re thrilled to share AxonSheet with Product Hunt today! I’d love to hear your thoughts, answer any questions, and learn what spreadsheet workflows you'd love to see automated next. Thank you for your support! 🚀
