InSights Into Data has a built in Spreadsheet feature that is fully Excel compatible. It is capable of reading and saving to Excel files.
Data can also be pushed into the Spreadsheet from both the Grid and the Pivot Grid by clicking one button.
Loading Data from the Grid
The above screen shot shows the Grid with data, and the arrow shows the Load Spreadsheet button that will take all that data and write it out to the built in spreadsheet feature.
A nice feature of this spreadsheet is that it will load the data from the Grids keeping all formatting and groupings!
Grid Data in the Spreadsheet
The above screen shot shows the grid data in the spreadsheet. You can see that it is the same data as in the Grid in the screen shot at the top of the page.
