This document describes string data processing using Util - String block.
Index
String Block
•
Process string data.
•
Supports data type conversion of integer and float.
1) String Concat
•
Merge multiple strings into one (target + Values).
•
Enter existing strings into the target, strings to add to the Values.
•
Click the button to add or delete Values

•
Example of using a block
2) String Index
•
Return the position of a particular character in a string (value) to a number.
•
Specify the starting point via offset.
•
Example of using a block
3) String Format
•
Use to format a string.
•
In format, enter the string formatting method.
•
Click the button to add or delete Values.

4) String Placeholder
•
Used for string interpolation, which converts a specific string to a string formatting.
•
String interpolation refers to a method of dynamically organizing a string by including values or calculated results within the string.
•
template : String Enter the string to which you want to apply the String Placeholder, specifying the part where the value changes as {key} where the value changes.
•
value : Specifies the value to assign to {key} in the template as a HashMap.
◦
It doesn't matter what order the values are in the HashMap because we're looking for values based on the key.
◦
If you register the same key multiple times, the value of the last value is registered.
◦
It can be insert String, Integer, Float, Boolean, null, etc. as values, but not HashMap and ArrayList.

JavaScript
Python
Java
C#
Ruby
PHP
5) String Charset Encode
•
Use to encode strings.
6) String Length
•
Check the length of the string to return the results to numbers.
•
Example of using a block
7) String ToArray
•
Convert a string to an Array.
•
Example of using a block
8) String SubString
•
Extract a part from a string
•
Enter start (start position) and length (number of characters to extract) as the index of the string.
•
Example of using a block
9) String Replace
•
Change one character to another in a string.
•
Enter search (target character) and replace (replace character) as a string.
•
Example of using a block
10) String Replace-Regex
•
Convert characters in a string that match a regular expression pattern.
•
In pattern, enter a regular expression pattern.
•
Below is a block example that converts the hexadecimal code 21 (!) if the string value contains a number ([0-9]).
11) String Split
•
Split the string by separating a specific character (column) from the string and outputs it as an array
•
In delimiter, enter a character (column) to act as a delimiter.
•
After division, the delimiter is deleted.
•
Example of using a block
12) String Split-Regex
•
Separate a specific character (column) from a string with a regular expression pattern and outputs it as an array
•
In pattern , enter a regular expression pattern to act as a delimiter.
•
After division, the delimiter is deleted.
•
Below is an example of separating a string that specifies a character not a capital (A-Z) or lower case (a-z) or number (0-9) as a delimiter in the string value . ‘,’ acts as a delimiter by registered regular expression patterns.
13) String LTrim
•
Use to delete the left blank in the string.
•
Example of using a block
14) String RTrim
•
Use to delete the right blank of the string.
