Left Node

The Left node extracts a specified number of characters from the left (beginning) of a string.

Left Node

Description​

The Left node returns the leftmost N characters from a string, where N is specified by the Count input.

Execution Inputs​

None (data node, no execution flow)

Variable Inputs​

  • Input (string): The string to extract characters from
  • Count (integer): The number of characters to extract from the left

Execution Outputs​

None (data node, no execution flow)

Variable Outputs​

  • Result (string): The leftmost Count characters of the input string

Special Notes​

  • If Count is negative, it is treated as 0
  • If Count is greater than the string length, returns the entire string
  • If Count is 0, returns an empty string
  • This node doesn't have execution pins - it's a pure data node

Example Usage​

Extract prefixes from strings, such as getting the first few characters of an ID, extracting area codes, or taking initials. Connect a string output to the Input and an integer to Count, then use the Result output in other nodes.
