{"id":7491,"library":"partialjson","title":"Partial JSON Parser","description":"The `partialjson` library provides a robust solution for parsing incomplete or partial JSON data in Python. It handles scenarios where JSON strings might be truncated or malformed at the end, returning the largest valid JSON object or array it can parse. The current version is 1.1.0, and releases appear to be infrequent, focusing on stability and bug fixes.","status":"active","version":"1.1.0","language":"python","source_language":"en","source_url":"https://github.com/iw4p/partialjson","tags":["json","parsing","incomplete-data","data-processing"],"install":[{"cmd":"pip install partialjson","lang":"bash","label":"Install `partialjson`"}],"dependencies":[],"imports":[{"wrong":"from partialjson import loads","symbol":"JSONParser","correct":"from partialjson import JSONParser"},{"wrong":"from partialjson import loads","symbol":"create_json_parser","correct":"from partialjson import create_json_parser"},{"wrong":"from partialjson import loads","symbol":"create_json5_parser","correct":"from partialjson import create_json5_parser"}],"quickstart":{"code":"from partialjson import loads\n\n# Example 1: Incomplete dictionary\nincomplete_json_dict = '{\"name\": \"Alice\", \"age\": 30, \"isStudent\": tru'\ndata_dict = loads(incomplete_json_dict)\nprint(f\"Parsed dict: {data_dict}\")\n# Expected: {'name': 'Alice', 'age': 30}\n\n# Example 2: Incomplete list\nincomplete_json_list = '[1, 2, {\"item\": \"value\"'\ndata_list = loads(incomplete_json_list)\nprint(f\"Parsed list: {data_list}\")\n# Expected: [1, 2]\n\n# Example 3: Deeply incomplete\ndeep_incomplete = '{\"user\": {\"id\": 123, \"name\": \"Bob\"}, \"products\": [{\"id\": 1' \nparsed_deep = loads(deep_incomplete)\nprint(f\"Parsed deep: {parsed_deep}\")\n# Expected: {'user': {'id': 123, 'name': 'Bob'}, 'products': []}","lang":"python","description":"This quickstart demonstrates how to use `partialjson.loads()` to parse various forms of incomplete JSON strings, including dictionaries and lists.
