from sb_json_tools import jt_iter

# This command tries to guess format and opens the file
data = jt_iter.load_from_file("data.json") # or data.jsonl

# Write to file, again guessing format
jt_iter.dump_to_file(data, "data.jsonl")

from sb_json_tools import json_iter, jsonl_iter

# Open and read the file
data = json_iter.load_from_file("data.json")

# Process file

# Write to file
jsonl_iter.dump_to_file(data, "data.jsonl")
