How do I do a VLOOKUP or join CSV files online without Excel?

Use the GINEXYS Node Editor to build a visual data pipeline in your browser. Here is the step-by-step tutorial:

• 1. Load your CSV files into the Table Formatter.
• 2. Click the Node Editor tab in the sidebar.
• 3. Your loaded sheets will appear as Table Nodes. Right-click on the "Out" port (the cyan color node).
• 4. Choose Join (or VLOOKUP) from the context menu to spawn an Operator Node.
• 5. Connect your second table to the new node, click the gear icon to select your configuration (Inner, Left, Full Outer), and run the pipeline.

For detailed technical documentation, see the Node Editor Engine Guide.
