Data ConverterInstall

Overview

This node operation converts JSON data into an HTML list. It takes a JSON input and generates either an ordered (numbered) or unordered (bulleted) HTML list based on the user's choice. This is useful when you want to display structured JSON data as a readable list in web pages, emails, or other HTML-supported environments.

Practical examples:

• Converting a JSON array of tasks into an HTML checklist.
• Displaying user comments or messages stored in JSON format as an HTML list.
• Transforming configuration or settings JSON into a human-readable HTML list for documentation.

Properties

Output

The node outputs a JSON object with a single field containing the generated HTML string representing the list. The HTML will be a <ul> element for unordered lists or an <ol> element for ordered lists, with each JSON item converted into an <li> element.

If configured to output binary data (not common for this operation), the binary data would contain the HTML content under the specified binary property name.

Dependencies

• No external services or API keys are required.
• The node uses internal utility functions for converting JSON to HTML lists.
• No special environment variables or n8n configurations are necessary.

Troubleshooting

• Invalid JSON input: If the provided JSON string is malformed, the node will throw an error. Ensure the JSON is valid and properly formatted.
• Unexpected JSON structure: The conversion expects JSON that can be represented as a list (e.g., an array). Complex nested objects may not render as expected.
• Empty output: If the input JSON is empty or does not contain listable items, the output HTML list may be empty.
• Binary output confusion: Setting the node to output binary data for this operation is unusual and may cause unexpected results.
