Spreadsheet processing/analysis by simple filter, group, sort, etc.
Data are imported from a spreadsheet and manipulated using a sequence of actions. Supported actions include:
Sort: sort rows according to one or more fields.
Filter: filter rows matching your criteria.
Group: group rows by one or more fields, calculates count/sum/average of each group.
The workflow symbolizes an assembly line. Each single action (acting like a worker on the assembly line) manipulates the data a little bit. All actions on the assembly line collaborate to achieve complex work.
