Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Sheetgraph is a Rust CLI and library that compresses Excel and Google Sheets into compact Markdown reports plus a formula dependency graph, so LLM agents can understand large spreadsheets without blowing the token budget. It groups formulas into copy-groups, profiles columns, and flags typed-over cells, with drill-down commands for exact values. The concept of an agent-native spreadsheet map is genuinely useful and well executed.

Target audience: AI engineers, backend developers, data analysts
