Load a CSV list mode file into the List Mode Utility to view file type, line count, and validation status.

You can load an existing list mode file in one of two ways:
  • Drag and drop a CSV file onto the dropzone in the center of the window
  • Click the dropzone to open a file browser and select a CSV file
When a file loads, the List Mode Utility automatically performs the following tasks:
  • Detects the file type
  • Counts the lines
  • Runs a full validation
The window then transitions to the File Loaded state, which shows the file path, type, line count, and validation status, along with available actions. The status indicator shows a green dot when the file is valid and a red dot when errors are found. You can click the X next to the file path to unload the file and return to the Landing state.
