Yes, thats an easy one...

Just create some blank columns to the right of the cells that contain the message.

Then go to "Data > Text To Columns" on the Excel main menu at the top.

Select "Delimited"
Select a "Space" as the delimiter by ticking the box.

This will then split the column up by the space.

The next column along will then show the "sub keyword" and you can filter by this.

Does that help?

Yes this can be done.

You need to login and look under REPORTS then click "Show Inbound SMS and Generate Reports".

Once loaded, at the bottom you hve the option to download these into a "CSV" file for excel . This file will contain the date, the number, the message, time and network.
