If it is not near-real.time-critical, all should work.
Measure with 10, 100, 1000, 10000 times of reccount()
to see any exponential dangers.

OTOH Record size probabky 1st to degrade total perf...

Calling into Dotnet MIGHT be safer for future JSON enhancements
but offer less ease debugging.

On the other hand, I need to process those records (receive the jsons recods conmvert it to cursors, do some processes on each record and this processes would give me a result in a cursor and convert this cursor back into json so the web service can return them properly. I should mention that the requirement to use Json comes from a partner to the company which I work for, we need to share some data. So, return "standard" Json should important too. Is nfJson capable of those two important aspects?

>>>Hi. I'll begin to develop a small web service in VFP 9. This web service will receive and send Json data. But I need to know what is the best available tool for encoding/decoding Json strings. By "best" I mean the easiest, fastest and most standardized tool to interact with VFP 9. Of course, if it would allow me to create cursor from Json, that would be a big plus.
