One Tool Example

Blob Convert has a One Tool Example. Visit Sample Workflows to learn how to access this and many other examples directly in Alteryx Designer.

Use Blob Convert to take different data types and either convert them to a Binary Large OBject (BLOB) or take a Blob and convert it to a different data type.

BLOB data types are often used to store images, audio, and other multimedia files and objects in a single, standardized format for simplified database management. They are a frequent file type in the Alteryx Designer.
