Attractive and powerful. Simplicity and elegance. TableTool helped me clean up a LastPass export in record time for import elsewhere. The only feature missing for me was some way to put in placeholders in empty cells in at least a semi-automatic way. Once I'd fixed up most of the issues, I had to reopen in OpenOffice to fill a mainly empty column after a sort. Table Tool makes it much easier to manipulate and check a CSV than OpenOffice. Like the right size screwdriver instead of a clumsy large Swiss Army knife. Better than most of the paid tools in the Mac CSV world.
