Pandas DataFrame to JSON: Removing Null Values

To convert a Pandas DataFrame to JSON and exclude null values, utilize the dropna() function before the conversion. This removes rows containing null values. Here's a code example showcasing this process:

import pandas as pd

# Assuming a DataFrame named 'merged_data4'

# Remove null values from the DataFrame
merged_data4 = merged_data4.dropna()

# Convert DataFrame to JSON, specifying 'records' orientation
output_data_json = merged_data4.to_json(orient='records')

# Print the converted JSON data
print(output_data_json)

In this code, dropna() removes null values from merged_data4. Subsequently, to_json() transforms the DataFrame into JSON, using the orient='records' parameter to control the conversion format.

Adapt the DataFrame name (merged_data4) in the code to your specific situation. Execute the example to test it. If you encounter issues, provide more details for assistance.
