TreeLike is an experimental tool allowing rapid exploration of the contents and inter-relationships across the columns of spreadsheet or CSV data. Use it to load any local CSV file. It immediately shows the distributions of values in all columns, and by laying out the columns in some nesting order, can show hierarchical relationships between values across columns. When two columns have a many-to-many relationship, the merge feature shows connections in both directions, not just from parent to child. And parent/child relationships can be reordered with one or two mouse clicks.
