    Below code can be adapted:

    load=ExtAPI.DataModel.GetObjectsByType(DataModelObjectCategory.BoltPretensionProbe)
count=load.Count
Name =[]
force=[]
Adjust=[]
filepath=r"D:\boltpretensionforceinfo.csv"
for i in range(0,count):
    press=load[i].WorkingLoad
    force.append(str(press).split()[0])
    Name.append(load[i].Name)
    Adjust.append(str(load[i].Adjustment)[0])
print("Bolt pretension reaction probe report Generated")
f=open(filepath,"w")
f.write("Bolt Pretension Probe Name"+ ","+"BlotPretension Load"+ ","+"Bolt Pretension Adjustment"+"\n")
for i in range(0,count):
    f.write(str(Name[i])+","+str(force[i])+","+str(Adjust[i])+"\n")
f.close()

    If you need time history values for pretension or adjustment you can use DPF. The pilot node of the bolt pretension load can be found from the load object.
    On this node, the reaction force in X will be the working load and the UX displacement will be the adjustment.
    Like with all things DPF, set the time scoping of the operators to get multiple time point results.
