Can we stores statistics data in excel?

The statistics data is getting stored in rmhdf5table. Can I get it in excel?

Hi,

you can save some metadata into an Excel file using the Reporting extension.

For the more precise question, check out the Aggregate operator. It has a setting "use default aggregation". This gives you the min, max or average - whichever function you select - for all attributes in one step. Just do this as often as you like. 

The "Attributes on rows" part can be done with De-Pivot.

Here's an example process:

This is probably more flexible than just getting the metadata. You can set breakpoints on the operators to see their intermediate results.

Actually I want to create a excel or CSV file which have high, low and average value of each attribute. e.g.

Attribute     High  Low  Average
Attribute1   100    50    75
