## Description

This MCP server provides AI assistants with Excel and CSV to JSON conversion capabilities, built by WTSolutions using Cloudflare Workers for serverless processing. The implementation offers two core tools: excel_to_json_mcp_from_data for converting tab-separated or comma-separated text data directly, and excel_to_json_mcp_from_url for processing Excel files (.xlsx) from URLs, both featuring automatic data type detection for numbers, booleans, dates, and strings with multi-sheet support for Excel files. Built with HTTPS security, no data retention policies, and robust error handling including format validation and network error management, it serves data analysis workflows requiring quick Excel-to-JSON transformation, web development projects needing structured data conversion, and AI-powered tools that process spreadsheet data without requiring local file handling or complex parsing libraries.
