CSV Editor Pro Screenshots

The main window.

In multiline editing mode, with warnings visible.

CSV Editor Pro can open files that don't adhere to the CSV standard.

Data in the CSV file can be displayed as a graph.  The X-axis is time or numerical.  The Y-axis is a numeric total.

A histogram can also be generated.  This is good for representing an accumulation of numeric data.

A pie chart can be generated from the CSV data.

When pasting rows, you can choose how the clipboard columns map to the CSV columns.

Cells on one or more rows can be shifted left or right.
