You need to first convert to a pandas.DataFrame using toPandas(), then you can use the to_dict() method on the transposed dataframe with orient='list': The input that I'm using to test data.txt: First we do the loading by using pyspark by reading the lines. %python import json jsonData = json.dumps (jsonDataDict) Add the JSON content to a list. rev2023.3.1.43269. str {dict, list, series, split, tight, records, index}, {'col1': {'row1': 1, 'row2': 2}, 'col2': {'row1': 0.5, 'row2': 0.75}}. toPandas () .set _index ('name'). By using our site, you toPandas () results in the collection of all records in the PySpark DataFrame to the driver program and should be done only on a small subset of the data. When no orient is specified, to_dict() returns in this format. If you want a defaultdict, you need to initialize it: str {dict, list, series, split, records, index}, [('col1', [('row1', 1), ('row2', 2)]), ('col2', [('row1', 0.5), ('row2', 0.75)])], Name: col1, dtype: int64), ('col2', row1 0.50, [('columns', ['col1', 'col2']), ('data', [[1, 0.75]]), ('index', ['row1', 'row2'])], [[('col1', 1), ('col2', 0.5)], [('col1', 2), ('col2', 0.75)]], [('row1', [('col1', 1), ('col2', 0.5)]), ('row2', [('col1', 2), ('col2', 0.75)])], OrderedDict([('col1', OrderedDict([('row1', 1), ('row2', 2)])), ('col2', OrderedDict([('row1', 0.5), ('row2', 0.75)]))]), [defaultdict(
