The above line of code writes the DataFrame to a gzipped JSON file called ‘compressed_data.json.gz’. Note that when the filename ends with ‘.gz’, Pandas infers that the data should be compressed using gzip, even if thecompressionargument isn’t explicitly set to ‘gzip’. Thecompress...
You can convert Pandas DataFrame to JSON string by using theDataFrame.to_json()method. This method takes a very important paramorientwhich accepts values ‘columns‘, ‘records‘, ‘index‘, ‘split‘, ‘table‘, and ‘values‘.JSONstands forJavaScript Object Notation. It is used to represent...
df = pd.DataFrame(data) Custom aggregation to nest data under each plan. nested_json = df.groupby(['CustomerID', 'Plan']).agg(list).reset_index().groupby('CustomerID').apply(lambda x: x[['Plan', 'DataUsage', 'MinutesUsage']].to_dict(orient='records')).to_json() print(nested_...
This article explains how to convert a flattened DataFrame to a nested structure, by nesting a case class within another case class. You can use this technique to build a JSON file, that can then be sent to an external API. Define nested schema We’ll start with a flattened DataFrame. Cl...
This creates a nested DataFrame. Write out nested DataFrame as a JSON file Use therepartition().write.optionfunction to write the nested DataFrame to a JSON file. %scala nestedDF.repartition(1).write.option("multiLine","true").json("dbfs:/tmp/test/json1/") ...
Let's dive into a practical example of converting a PDF to JSON using Python. We'll cover setting up your environment, extracting text and tables, and structuring the data into JSON. Setting Up the Environment First, ensure you have Python installed on your system. Then, install the necessar...

To use this function, we need first to read the JSON string using json.loads() function in the JSON library in Python. Then we pass this JSON object to the json_normalize(), which will return a Pandas DataFrame containing the required data. import pandas as pd import json from pandas ...
Convert JSON to CSV using Pandas, Pandas is a library in Python that can be used to convert JSON (String or file) to CSV file, all you need is first read the JSON into a pandas DataFrame and then write pandas DataFrame to CSV file....
在上面的代码中,我们首先将JSON数据读取到一个列表中。然后,我们使用pandas库将列表转换为DataFrame对象。接下来,我们使用pyarrow库将DataFrame转换为Table对象。最后,我们使用pyarrow.parquet模块将Table写入Parquet文件。 流程图 下面是将JSON列表转换为Parquet文件的流程图: ...
