not able to compare excel files with charts in it

[Priya]

Hi,
I have an excel file created automatically through VBScript. The generated
file basically has a worksheet with some data, some formulas and another
worksheet with chart.

I want a way to compare the generated file with a master file I have. Is
there any utility available or can it be done programatically in VBScript?

I tried some tools like excel compare, diffdoc; none of them seem to compare
charts.

thanks
Priya
