The StringSubstring node extracts a portion of text from a larger string. It takes a starting position and ending position to define the section you want to extract, then returns the text between those two positions.

| `start` | The starting position index for the substring. The first character is at index 0. | INT | Yes | - |
| `end` | The ending position index for the substring. The character at this index is not included in the result. | INT | Yes | - |

## Outputs
