xlsx-tools-mcp

An MCP server providing accurate, structure-preserving read and write access to Excel (.xlsx) files. It supports reading cell ranges, searching values, aggregating data, writing cells and formulas, managing sheets, applying styles, and creating native Excel objects like tables and charts. It ensures formula accuracy via LibreOffice recalculation and prevents data corruption through per-file locking and path confinement.
