Overview

This custom node provides a set of text processing and utility operations under a single "Custom" resource. The "Extract Info" operation specifically parses input text containing colon-separated key-value pairs and extracts this structured information into JSON format.

Typical use cases include:

  • Parsing user-submitted forms or messages where data is provided as lines like key : value.
  • Extracting contact details, configuration parameters, or any structured info embedded in plain text.
  • Automating data extraction from logs, emails, or notes formatted with simple key-value pairs.

For example, given the input text:

name : John Doe
email : john@example.com
phone : +60123456789

the node will output a JSON object with keys name, email, and phone mapped to their respective values.

Properties

Name Meaning
CJ Token Your API token from sifuim.com. This is required for authenticating requests to the service.
Text Text containing information in "parameter : value" format. Multiple lines can be provided.

Output

The output JSON contains the following fields:

  • originalText: The original input text string.
  • extractedInfo: An object where each key corresponds to a parameter extracted from the input text, and its value is the associated value.
  • totalExtracted: The total number of key-value pairs extracted.

Example output JSON:

{
  "originalText": "name : John Doe\nemail : john@example.com\nphone : +60123456789",
  "extractedInfo": {
    "name": "John Doe",
    "email": "john@example.com",
    "phone": "+60123456789"
  },
  "totalExtracted": 3
}

No binary data output is produced by this operation.

Dependencies

  • Requires a valid API token credential from sifuim.com to authenticate and authorize usage.
  • The node internally calls a validation function to verify the API token before processing.
  • Usage of the node may deduct credits from the user's account on the external service.

Troubleshooting

  • Invalid or missing API token: The node requires a valid API token. Ensure you provide your token correctly in the "CJ Token" property.
  • Malformed input text: The text must contain colon-separated key-value pairs. Lines not matching this pattern may be ignored or cause incomplete extraction.
  • Credit deduction failure: If credit deduction fails silently, it might indicate network issues or invalid tokens. Check connectivity and token validity.
  • Unhandled operation error: If an unsupported operation is selected, the node throws an error indicating the operation is not implemented.

To resolve errors:

  • Verify the API token is correct and active.
  • Format the input text properly with one key-value pair per line separated by a colon.
  • Use the "Continue On Fail" option if you want the workflow to proceed despite individual item errors.
