With large data sets in a ListGrid which export option has the best performance in general out of exportData and exportClientData?
I have observed that exportClientData still sends all of the rows to the server then receives them back as the downloaded file, while exportData uses a fetch() call to get the rows then formats, and sends the file.

exportData() is recommended for larger exports, since all data does not need to be loaded to the browser in order for the export to take place.

If the data is in the clients browser all ready why does it have to be sent to the server to get downloaded as a csv file?

When using exportClientData, the data sent to the server contains the formatting that was performed in the browser, which the server cannot replicate.
