Hi @Simon Cowx

Here's the short description for each:

Bridge - Connects Smartsheet to other Software

DataShuttle - Connects Smartsheet to Excel. This tool has tons of cababilities though. If I had to pick one, this would be it even though they all have very unique purposes.

DataMesh - Works like a behind-the-scenes indexmatch but also has the ability to automatically add rows to a target sheet if the unique identifier is found on the source but not the target.

Dynamic View - Gives the ability for users to view and update certain information on a sheet or report without needing access to the entire sheet/report.

I hope that helps. I don't implement Bridge too often but the other (3) are commonly used. Let me know if you have any more questions or if you have a specific challenge you are trying to solve.

Matt
