JSON templates allow you to control the look and feel of different pages of the online store using sections.
JSON templates are data files that store a list of sections to be rendered, and their associated settings. Merchants can add, remove, and reorder these sections using the theme editor.
When a page is rendered with a JSON template, the sections are rendered in the order specified by the order attribute, with no markup between the sections. JSON templates can render up to 25 sections, and each section can have up to 50 blocks.
Although JSON templates differ from Liquid templates in their contents, they are still template files that support the following Shopify theme features:
- All template types, except for gift_card and robots.txt.
- Alternate templates.
When you build a JSON template, you should also build a section that contains the core functionality for the template. For example, when you're building a list-collections JSON template, it should reference a section that uses the collections object.
A theme can contain up to 1,000 JSON templates. After the limit is reached, you can't create new JSON templates.
JSON templates must be valid JSON files. The root should be an object with the following attributes:
||String||No||A name for the template.|
The filename of the layout to use when rendering the template. For example, specify
The default layout is
Use the value
||String||No||The HTML wrapper element for the template's sections. To learn more, refer to The wrapper property.|
An object that uses section IDs as keys, and section data as values. This attribute needs to contain at least one section.
Duplicate IDs within the template aren't allowed.
The format of the section data is the same as section data in settings_data.json. To learn more, refer to Section data. JSON templates can render up to 25 sections, and each section can have up to 50 blocks.
An array of section IDs, listed in the order that they should be rendered. The IDs must exist in the

The filename must be a valid theme template type, with an optional suffix for an alternate template. For example, a product template can be named
A template can only exist as a JSON or Liquid template, not both. For example, if
product.liquid already exists, then you can't create

wrapper property makes it possible to insert HTML tags around all of the sections in a JSON template. You can use the following HTML tags:
For example, a JSON file with the following
wrapper property produces the following output:
Section dataAnchor link to section titled "Section data"
sections attribute of JSON templates holds the data for the sections to be rendered by the template. These can be either theme sections or app sections. You can't share section data across JSON theme templates, so each section must have an ID that's unique within the template.
JSON templates can render up to 25 sections, and each section can have up to 50 blocks.
You can add sections to a template in code, or through the theme editor. The sections that are available to be added to a template in the theme editor might be limited by the
disabled_on attribute of the section schema. If no
disabled_on attribute is defined, then the section can be added to any template.
The following table outlines the format of section data:
||String||-||A unique ID for the section. Accepts only alphanumeric characters.|
||String||Yes||The filename of the section file to render, without the extension.|
||String||-||A unique ID for the block. Accepts only alphanumeric characters.|
||String||Yes||The type of block to render, as defined in the schema of the section file.|
||Array||No||An array of block IDs, ordered as they should be rendered. The IDs must exist in the
||String||-||The ID of a setting as defined in the schema of the section or the block.|
||(multiple)||-||A valid value for the setting.|
For example, the following template renders the
product-recommendations.liquid section files on product pages:

In the theme editor, Shopify exposes a custom CSS setting at the theme and section level. Any custom CSS that merchants add to a section instance is stored in a
custom_css attribute in the section data.
This setting is intended to enable users to customize the look and feel of their storefront without editing theme code. As a theme developer, you shouldn't add this setting, or edit the value of this setting after it's set. Instead, you should use dedicated CSS assets and
stylesheet Liquid tags, and introduce customization options for CSS in these areas using theme settings.
