Guides: query CSVs and Google Sheets from AI agents and apps
How to let agents and apps query your spreadsheets instead of reading them, step by step.
AI chats and agents
Claude, ChatGPT, Cursor and other MCP clients.
- Connect Google Sheets to Claude (private sheets, exact totals)Add a Google Sheet to Claude as a custom connector so it queries the rows instead of reading them. Works with private sheets and large tabs.
- Google Sheets MCP server: hosted, no Google Cloud setupUse a hosted MCP server for Google Sheets in Claude Code, Cursor and other MCP clients. No service account, no local process.
- CSV MCP server, hosted: query CSVs from Claude, ChatGPT and CursorTurn a CSV file or CSV link into a remote MCP server your agents can query, without running anything locally.
- ChatGPT and Claude CSV limits: analyze big files without uploading themWhy large CSV uploads fail or give approximate totals in AI chats, and how to let the model query the file instead.
Automations and apps
REST for n8n, Make and your own code.
- Turn a CSV into a REST APIUpload a CSV and query it over HTTP with filters, sorting and aggregates. API keys, versioned results, no server to run.
- Use Google Sheets as a read-only API with filters and aggregatesQuery a Google Sheet over REST with filters, group-by and totals, kept in sync with the sheet.
