Follow this way:
1. In Pspice Schematics, check Analysis->probe setup->Data collection->Text data file format(CSDF) to ON.
2. I suggest you set data collection only for those test point which you need.
3. Run simulation again, then you will find a file with a extension of .CSD
CSDF is an ASCII data file format that is commonly used by different simulators. You can use excel to process data.
If you need more interpolations, then reduce step ceiling at Analysis->setup->transient->step ceiling to a small value.
