How many days 1 min data can be exported to excel using export chart to excel option?

I am trying to export the 1 min data for 120 days, but the PI system gets hanged out.

It works perfectly for 30 days.

Please help me to download 120 days 1 min data.

You can export as many as you can, i think it is based on system processor speed. 

Max 120 days option is there, and when we select it , system gets hanged.
