Overview

This node performs various utility text and data transformations, including replacing keywords in a template text with values from a JSON object. Specifically, the 'Replace Keywords' operation takes a template string containing placeholders (e.g., {{key}}) and replaces these placeholders with corresponding values provided in a JSON replacements string. This is useful for dynamically generating personalized messages, notifications, or documents by substituting placeholders with actual data.

Use Case Examples

1. Generating personalized order confirmation messages by replacing placeholders like {{name}} and {{order_id}} with customer-specific values.
2. Creating customized email templates where keywords are replaced with user data from a JSON object.

Properties

Output

JSON

• success - Indicates if the operation was successful.
• operation - The operation performed, here it is 'replaceKeywords'.
• original_text - The original template text before replacements.
• result_text - The resulting text after all replacements have been made.
• replacements - The parsed JSON object containing the replacement key-value pairs.
• replacement_count - The total number of replacements made in the template text.
• replaced_keys - An array of keys that were replaced in the template text.

Troubleshooting

• Ensure the 'Template Text' input is not empty; otherwise, the node will throw an error indicating the template text is required.
• The 'Replacements (JSON)' input must be valid JSON; invalid JSON will cause a parsing error and the node will throw an error indicating invalid JSON in the replacements field.
• Placeholders in the template text must exactly match keys in the replacements JSON enclosed in double curly braces (e.g., {{key}}). Mismatched keys will not be replaced.
