What data formats does the Data Profiler support?

The skill works with any data that can be loaded into a Pandas DataFrame, including CSV, Parquet, JSON, and SQL query results.

Is this skill suitable for large datasets?

It provides memory usage statistics and efficient summaries, though performance is ultimately dependent on the memory limits of the environment where the Python script is executed.

Does it identify missing data patterns?

Yes, it specifically profiles missing data patterns, including 'co-missing' columns where data tends to be absent across multiple fields simultaneously.

Can I customize the correlation threshold?

Yes, the correlation analysis function allows you to specify a threshold to filter for only the most significant relationships.
