How to turn "find -exec" results into different columns?

Question

When launching a find -exec I get a list of results, separated by colons. Is there a way to turn those colons into some kind of "columns" separators (preferably a list of spaces)?

Turn:

Prompt> find ./ -name "*.*" -exec grep "namespace" {} /dev/null \;

./Alarm/AddedHandler.cs:namespace Alarm
./Alarm/DeletedHandler.cs:namespace Alarm
./Alarm/UpdatedHandler.cs:namespace Alarm
./Connections/AddedHandler.cs:namespace Connections
./Connections/DeletedHandler.cs:namespace Connections
./Connections/UpdatedHandler.cs:namespace Connections
./Robot.Api/AddedHandler.cs:namespace Robot
./Robot.Api/DeletedHandler.cs:namespace Robot
./Robot.Api/UpdatedHandler.cs:namespace Robot

... into:

Prompt> find ./ -name "*.*" -exec grep "namespace" {} /dev/null \; | <turn_colon_into_list_of_spaces>

./Alarm/AddedHandler.cs         : namespace Alarm
./Alarm/DeletedHandler.cs       : namespace Alarm
./Alarm/UpdatedHandler.cs       : namespace Alarm
./Connections/AddedHandler.cs   : namespace Connections
./Connections/DeletedHandler.cs : namespace Connections
./Connections/UpdatedHandler.cs : namespace Connections
./Robot.Api/AddedHandler.cs     : namespace Robot
./Robot.Api/DeletedHandler.cs   : namespace Robot
./Robot.Api/UpdatedHandler.cs   : namespace Robot

(I don't care whether or not the colons are still present.)

You can pipe the output to column:

find ... | column -ts:
