# S3 CSV Input

The S3 CSV Input step identifies and loads a CSV file from an [Amazon Simple Storage Service (S3)](https://docs.aws.amazon.com/AmazonS3/latest/dev/Welcome.html) bucket into your transformation.

**Note:** [Using the Text File Input step on the Spark engine](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/PDI/Transformation%20steps/PDI%20transformation%20steps%20reference%20\(overview\)/Text%20File%20Input%20cp/Select%20an%20engine%20\(Text%20File%20Input\)/Using%20Text%20File%20Input%20on%20Spark%20engine%20cp=GUID-7483A8B3-9CD6-4725-9054-A85C353FF912=2=en=.md) is recommended for extracting data from an Amazon S3 bucket when you are using Spark as your [Adaptive Execution Layer](/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/adaptive-execution-layer-cp-landing-page.md).
