# Supported File Types

When your connection is storage-based (e.g., cloud storage services), you can upload the following file formats:

* **Data Formats:**
  * CSV
  * JSON
  * Parquet
  * Avro
  * Delta Lake
* **Document Formats:**
  * PDF (GCP Support Only)
  * XML
* **Automatic File Type Detection**\
  There is also an Automatic file type option. When selected, Telmai attempts to determine the file type by inspecting the file extension.
