How to read/write the json file from platformio

Hello everyone, I am new to this platform and working with esp32. I want to create, read/write the JSON file from platformio. Can anyone help me with any solution or guide?

Look into LittleFS and ArduinoJSON. There are tons of guides online.

Yeah, I have tried it and it’s working fine. But I want to open my file from the directory. Is it possible to open it? Thank you
