About Multi‑List Tools
How to Use Multi‑List Tools
The Multi‑List Tools page lets you work with multiple lists simultaneously. You can merge lists to obtain a union of unique items, intersect lists to find common elements, import data from CSV files, and visualize overlaps using a Venn diagram (supported for 2 or 3 lists). In addition, explore detailed set operations with an interactive dashboard featuring pairwise comparisons, a global overlap histogram, and a custom combination explorer.
Key Features
  • Merge Lists: Combine all unique items from your lists (union) by removing duplicates.
  • Intersect Lists: Find the common items shared across your lists.
  • Venn Diagram Visualization: Visualize overlaps between 2 or 3 lists. Click on any count to view detailed subset information.
  • CSV Import: Import lists from a CSV file. If the first row contains headers, each column will be treated as a separate list.
  • Case Sensitive Matching: Toggle case sensitivity for precise comparisons.
  • List Management: Easily add new lists or remove extra lists with the provided buttons.
  • Interactive Dashboard: Access advanced features like a global overlap histogram, interactive pairwise comparison matrix, and custom combination explorer to analyze your data in-depth.
  • Export Options: Download visualizations as SVG or PNG files, and export detailed results as CSV.
Getting Started
Begin by entering your list items in the input area using your chosen delimiter or by importing a CSV file. Then, select the desired operation from the toolbar—whether merging, intersecting, or switching to the dashboard for detailed analysis. The output will appear below, and you can click on visual elements to drill down into the data.
