Canvas editor

Background CSV loading

Keep using the app and see progress while a CSV loads.

How it works

Drop a CSV onto Canvas, or enter its path in a CSV Input and click Load. The card shows the load status while you work on other nodes. When the import finishes, the card displays the row count and a preview of the data.

Load a sample CSV, inspect Status guide while it parses, then preview the 1,350,000 imported rows. The replay pauses at each step.
