Spreadsheet data is imported into a no-code database (NocoDB)
System connects with an AI data analyst agent
Agent accesses table metadata and column information
Query Processing:
Users input natural language questions
AI agent interprets queries and converts them to database filters
System retrieves relevant data using filter formulas
AI synthesizes responses with analysis and insights
Advanced Capabilities:
Performs comparative analysis across multiple data points
Handles complex multi-part queries
Automatically creates visualizations:
Visualization AI Agent figures out the data and the chart type and generates professional visualization using Quickchart
Step by step setup:
Create account on nocodb.com
Create table by importing csv, copy table id
Create API token https://app.nocodb.com/#/account/tokens
In workflow, settings node, update with table id
In NocoDB tool node, setup authentication with API token created in step 3
Specify the workspace and base fields after connecting to NocoDB
