Understanding the Need for Conversion.
In your eCommerce journey, you may have scenarios where price, quantity, or other numeric values are stored as strings. Converting these strings to integers is essential for comparisons, arithmetic operations, or simply for displaying the data in a different format.

Step 1: Identify the String Variable.
Before you can convert it, you need to identify the string variable you want to change.
For example:
{% assign string_number = "100" %}Step 2: Use the plus Filter for Conversion.
Shopify Liquid provides an easy way to convert the string to an integer using the plus filter:
{% assign integer_number = string_number | plus: 0 %}This will convert "100" into 100.
Step 3: Print the Output.
{% assign string_number = "100" %}
{% assign integer_number = string_number | plus: 0 %}
<p>The string is: {{ string_number }}</p>
<p>The integer is: {{ integer_number }}</p>
Step 4: Output.
Error Handling:
What if the string is not a number? It’s wise to include error handling. If you apply the above methods to a non-numeric string, the result will be 0. Depending on your needs, you may want to include logic to handle this scenario appropriately.
Practical Examples.
Here are some practical examples where string-to-integer conversion could be useful:
- Calculating Discounts: If you have the original price as a string and want to apply a discount, conversion to an integer will be necessary for the calculations.
- Inventory Management: If the inventory levels are stored as strings, converting them to integers will enable arithmetic operations to increase or decrease stock levels.
