What it does
Gives an agent direct control over Excel workbooks — creating sheets, writing values, setting formulas and formatting, building charts and pivot tables — with no Microsoft Excel required on the machine. Handy both for automation and for environments that simply have no Excel. Generated formulas frequently reference not-quite-right ranges, so check the totals yourself, and hand it copies rather than originals. MIT.
