Transform JSON file into CSV (without breaking logic and structure)

Job ID: 32102529

Budget: $30 – $250 CAD

Take a look at the .rds file below, it's a JSON file. I need it to be processed in R. It contains nested lists. I need the file to be flattened and exported in csv files in nice tables.

Just using unlist() doesn't work as it breaks all logic/connections. If you have extensive knowledge working with JSON files in R, please bid. Thank you.
