This page will explain what transformers are and where they are used. The following transformers are available:

Name	Description
Apply in a while loop	Runs a transformer in a while loop.
Apply operator	Apply an operation to fields in the data.
Apply transformer conditionally	Executes a transformer when a condition is met.
Chain transformers	Executes a list of data transformers in sequence.
Convert data to arrays	Transforms JSON objects to arrays.
Copy using a path	Takes a part of the entity data and copies it.
Copy using an accessor	Copies a part of the entity data to another location within the entity data, while leaving the original content unchanged.
Execute GraphQL request	Executes HTTP requests to GraphQL APIs.
Execute HTTP request	Executes HTTP requests to web endpoints.
Execute SOAP request	Executes requests to a web service via the SOAP protocol.
Execute SQL query	Executes SQL queries.
Execute XML-RPC request	Executes requests to an XML-RPC web service.
Execute entity transformers	Executes one or more entity transformers in sequence.
Expand path	Combines the existing data and value moving all paths from source to destination pattern.
Filesystem: Copy a file	Copies a file to a specified destination.
Filesystem: Move a file	Moves a file to another directory or filesystem.
Filesystem: Read files	Reads the contents of a file from a filesystem and adds it to the data.
Filesystem: Write files	Writes data to a file on a filesystem.
Flatten nested structure	Recursively flattens a nested data structure.
For each item	Loop over items and apply a transformer to each.
Group records	Groups items from a list by the value of a specific key.
Map array or object items	Performs actions on arrays and objects.
Map keys	Performs actions on keys in the data.
Map values	Transforms values in the data.
Merge transformer output	Combines the output of a transformer with the existing data.
Move using a path	Takes a part of the entity data and moves it to a new location in the entity data. This transformer can be used to move the value of a key, or a nested key, like “product”, or “product.name” into a new key like “itemName”, or “item.itemName”.
Move using an accessor	The Accessor-move Transformer is used to take a part from the entity data and move it somewhere else in the structure.
Pause processing	Pause processing for a number of seconds.
Recursively copy values to children	Copies a value to nested child properties recursively.
Remove keys by accessor	Removes certain parts of the context data based on accessors.
Remove values	Removes values from the data based on patterns.
Remove values by condition	Removes values from the data when they meet a specific set of conditions.
Render a template	Use a template with expressions and filters to render output based on the supplied data.
Send email	Sends an email.
Set global variable	Sets a variable in the global scope.
Set values	Adds or updates data at specific keys in the context. Supports placeholders to reference existing data.
Storage: Delete all items	Deletes all items in a storage.

Storage: Get all items	Gets all items from a storage.
Storage: Get item	Gets an item from a storage based on an identifier.
Storage: Load progress	Makes the data saved in a storage by the “Storage: Track progress” transformer available in the entity data.

Storage: Save item	Saves data to a storage with an identifier.
Storage: Track progress	Tracks the progress of a data synchronization.
Storage: Update item	Updates values of an item saved in a storage.
