The Excel MCP Server provides Claude with comprehensive read, write, and analysis capabilities for Excel and CSV files through 37 specialized tools.
Read & Navigate: Read entire files or specific cells/ranges, get headers, search values, filter rows by conditions, and aggregate columns (sum, average, count, min, max).
Large File Handling: Stream large files (100MB+) in chunks and get file analysis with chunking recommendations.
Write & Format: Create new Excel/CSV files (single or multi-sheet with formulas and inter-sheet references), add sheets to existing files, export analysis results, apply cell formatting (fonts, colors, borders, alignment, number formats), and auto-fit columns.
Analytics: Perform statistical analysis, correlation analysis, data profiling, and create pivot tables.
Financial Modeling: Conduct DCF valuation, budget vs. actual variance analysis, financial ratio analysis with industry benchmarks, scenario/what-if modeling, and trend analysis with forecasting.
Data Cleaning: Find/manage duplicates, batch clean data (trim whitespace, fix dates/phones/names/currency, remove empty rows), and perform intelligent VLOOKUP with fuzzy matching and error handling.
Bulk Operations: Aggregate and filter data across multiple files in parallel.
Validation: Cross-validate data integrity across related files (referential integrity, data completeness, value ranges).
AI-Powered: Evaluate Excel formulas, convert natural language to formulas/commands, explain formulas in plain English, get AI-powered analysis suggestions, and check AI provider status (Anthropic, OpenAI, DeepSeek, Gemini, or local fallback).
Enables AI-powered natural language data queries and formula generation through OpenAI's API for intelligent spreadsheet analysis.
