Data ConverterInstall

Overview

The node provides a versatile data conversion tool that supports multiple encoding and decoding operations across various data formats. Specifically, the HTML Decode operation under the Encoding resource decodes HTML entities in a given text string back to their corresponding characters. This is useful when you receive or scrape HTML-encoded content and want to convert it into plain readable text.

Common scenarios include:

• Cleaning up HTML-encoded user input or web-scraped data.
• Preparing text for further processing or display where HTML entities are not desired.
• Decoding email bodies or other content that may contain encoded HTML entities.

Example:
Input: "<div>Hello & welcome!</div>"
Output: "<div>Hello & welcome!</div>"

Properties

Output

• The output JSON contains a field named result which holds the decoded string with all HTML entities converted to their literal characters.
• This operation does not produce binary data output.

Example output JSON structure:

{
  "result": "<div>Hello & welcome!</div>"
}

Dependencies

• No external API or service dependencies are required.
• The node uses internal utility functions for HTML entity decoding.
• No special credentials or environment variables are needed.

Troubleshooting

• Empty or unchanged output: Ensure the input string actually contains HTML entities to decode.
• Malformed input: If the input string is not properly encoded or contains invalid entities, the output might be incorrect or partial.
• Large inputs: Very large strings might impact performance; consider splitting input if necessary.
• Error messages: Errors during execution typically relate to invalid input types or missing required parameters. Verify that "Input Data" is provided as a string.
