 "page_title": "How to read and update a connected Excel workbook from Chat with Codexless",
 "summary": "Let ChatGPT search, read, write, and format ranges in a workbook that is already connected.",
 "who": "An analyst or operations user who keeps data in an Excel workbook and wants ChatGPT to update it during the same conversation.",
 "problem": "Reviewing and editing many ranges by hand, or switching between Chat and Excel, slows down routine workbook changes.",
 "outcome": "ChatGPT reads sheet metadata and ranges, searches the workbook, writes values, and applies formatting through the public Excel Preview tools.",
 "steps": [
  "Complete the Codexless install and start the HTTP service for your platform.",
  "Connect the target workbook through the supported Document Control / Excel Add-in path, since Codexless does not use CUA for public Excel work.",
  "In Chat, ask ChatGPT to run excel_status to confirm the workbook is connected.",
  "Ask ChatGPT to read the sheet metadata or ranges, then describe the exact cells it plans to change.",
  "Approve the write or formatting request, then ask ChatGPT to read the changed range back and confirm the values."
 ],
 "agent_prompt": "Using the Codexless repository at https://github.com/liyana31811/Codexless, ask ChatGPT to check the connected workbook with excel_status, then update <sheet-and-range> with <new-values>. Verify the change by reading back the same range with excel_read_ranges before reporting success.",

 "difficulty": "Intermediate",

 "requirements": [
  "Node.js 22 or newer",
  "A working local Codex installation (Codex Desktop is optional if a working CLI or runtime is available)",
  "A supported platform: Windows, Apple Silicon macOS (arm64), or Ubuntu Linux (x64) Technical Preview",
  "A ChatGPT plan; Plus and Pro have been verified working",
  "An authenticated Tunnel or remote MCP endpoint, plus a ChatGPT custom app or developer-mode MCP connection, so ChatGPT can reach your local Codexless"
