Transform

The Transform action connector helps in manipulating texts and numbers as required. It helps you to manipulate and structure data according to our needs.
For example, suppose in the previous trigger specific data is selected to be displayed. In that case, the action defined by the Transform connector can manipulate or change it to meet your display requirements.

Set up the Transform modifiers

Perform the following steps to set up the Transform action connector:

1. Click Configure Action Step from the left navigation panel.

2. Click Action Step to configure third-party services.

3. Within the Configure Action Step, click the Transform connector.
   
4. You will see these actions under the Choose an Action tab: Template and Transform.
   
5. On the Transform Configure Action page, enter the following details:
   1. Click the Add Input button, and enter a variable name for the Input Name (say, “name”) and an Input Value for the variable (say, “john” in lowercase letters).
      

      Note: You can even pass the value directly into the Transformation box.

   2. Let’s enter the JSON code that uses the “capitalize()” modifier in the Transformation box. Use the following code: {“result” : “{capitalize(name)}” }
      
6. Click Proceed.
7. Check if the details are correct. If yes, click Test Action.
   
8. Once set, click Save and Exit.

This sets up the Transform action connector.

Transform Modifiers

Transform modifiers help in manipulating texts and numbers as per our needs. This function utilizes JSON code and modifiers to transform data.
The Transform connector also helps in mapping different JSON objects into one object, as seen in the sample transform input data:

{
  "first_name" : "{user_first}",
  "last_name" : "{user_last}",
  "full_name" : "{join(user_first,user_last,' ')}",
  "country" : "india",
  "time" : "{now('toISO')}"
}

The Transform function has specific modifiers that can manipulate the data. Let’s look at the applicable transform modifiers in detail.

truncate

Use this modifier to reduce the length of a string to a specific number of characters or words using ellipses or word-break options.

Note: The boolean value (true, false) implies whether you want to break the word or not. True means you want to break the word, and false means not. The space after the word is considered a break.

Example: truncate (string,number of characters,'ending string', ‘word break’)

Note: If the limit for the number of characters is more than that of the string, the output will contain the complete string without ellipses.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

Here’s a screenshot that shows the input when the word break is set to true by default.

Here’s a screenshot that shows the output:

Note: In the truncate modifier, string and the number of characters are the two mandatory fields. If we do not specify the ending string, it would take the ellipses (...) or any other characters the user enters such as (***).

replace

Use this modifier to replace any character, word, or string given in the 2nd argument with the 3rd argument.
Example: replace(Data, 'one char, one word or string', 'with this string')

Note: The replace modifier can only replace the first occurrence of a character/word/string.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

replaceAll

Use this modifier to replace all the characters, words, or strings given in the 2nd argument with the 3rd argument.

Note: The replaceAll modifier will replace multiple occurrences of a character/word/string with the same pattern.

You can also pass the data configured from the previous step and replace the content. Here is an example:

3. Click Proceed.
4. Check if the details are correct. If yes, click Test Action.
   
5. Once set, click Save and Exit.
   

Examples

Let’s look at some of the basic examples of the Template action.

Example 1:

Data Array:

data = [{name: "Alice", age: 25}, {name: "Bob", age: 30}]

Explanation:

• [[#each data]] loops through the data array.
• [[this.name]] accesses the name property of each object in the array.
• [[#unless @last]] checks if the current item is not the last one in the array; if it is not, a comma is added.

This results in the names being joined with commas, except after the last name.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

Example 2:

Data Array:

data = [{name: "Alice", age: 25}, {name: "Bob", age: 30}]

Explanation:

• [[#each data]] loops through the data array, creating a list item (<li> </li>) for each iteration that displays the name value. The result is an HTML list where each name appears as a list item.

This results in an unordered list.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

Example 3:

Data Array:

Data = { author: true, firstName: "Yehuda", lastName: "Katz"}

Explanation:

• [[#if Data.author]] checks whether the author exists.
• If the author is present, the full name is displayed within an <h1> tag.
• If the author is not present, the message "He is not an author" is displayed.
• In this scenario, since the author exists, the name is shown.

Here’s a screenshot that shows the input

Here’s a screenshot that shows the output:

Example 4:

Data Array:

Data= { isAdmin: false}

Explanation:

• [[#unless Data.isAdmin]] checks if isAdmin is false.
• If it is, the message "You are not an admin" is displayed.
• In this case, since isAdmin is false, the message is shown.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

Example 5:

Data Array:

data = 
{ products = [ { "name": "Laptop", "price": 999, "inStock": true }, { "name": "Smartphone", "price": 499, "inStock": false }, { "name": "Tablet", "price": 299, "inStock": true } ] } 

Explanation:

• The template uses [[#each products]] to loop through the products array.
• For each product, it displays the name, price, and stock status within a list item (<li>).
• The [[#if inStock]] helper checks if the product is in stock and conditionally shows the correct status.
• The result is an HTML list of products, showing their names, prices, and stock availability.

Here’s a screenshot that shows the input:

Here’s a screenshot that shows the output:

Example 6:

Data Array:

Data = { "data": ["a", "b", "c", "d", "e"] }

Explanation:

• The [[size Data]] helper counts the elements in the Data array.
• The output is the total number of items, which, in this case, is 5.

truncate

Use this function to reduce the length of a string to a specific number of characters or words using ellipses or word-break options.

Note: The boolean value (true or false) indicates whether you want to break the word. True means you do want to break the word, while false means you do not. Note that a space following the word is considered a break. For instance, with a boolean value of true, 'hello world' would break after 'hello'.

Example: [[truncate string,number of characters,”ending string”, “word break”]].

In the above example:

• truncate is the helper function
• string is the input string
• number of characters is the limit to reduce the input string length
• ending string is the special character or ellipses used to end the string
• word break specified as true/false to break the word

Note: If the limit for the number of characters is more than that of the string, the output will contain the complete string without ellipses.
