File formats for downloading and exporting explanation data. This enum defines the supported file formats for downloading explanation results from Fiddler. Different formats offer different advantages in terms of performance, compatibility, and data structure preservation.

​
PARQUET

Apache Parquet format for efficient columnar storage

​
CSV

Comma-separated values format for broad compatibility

​
Examples

Downloading explanations in different formats: 
# Download as Parquet (recommended for large datasets)
parquet_data = model.download_explanations(
    format=fdl.DownloadFormat.PARQUET,
    chunk_size=1000
)

# Download as CSV (better compatibility)
csv_data = model.download_explanations(
    format=fdl.DownloadFormat.CSV,
    chunk_size=500
)
Choose format based on your analysis tools and data size requirements. Parquet is recommended for large datasets due to compression and performance.
