### String functions

| Name        | Syntax                           | Sample                              | Output                                                                    |
|-------------|----------------------------------|-------------------------------------|---------------------------------------------------------------------------|
| **CONCAT**  | `CONCAT(str1, [str2,...])`       | `CONCAT({field1}, ' ', {field2})` | Concatenated string of input parameters                                   |
| **LEFT**    | `LEFT(str1, n)`                  | `LEFT({field}, 3)`                 | `n` characters from the beginning of input parameter                      |
| **LEN**     | `LEN(str)`                       | `LEN({field})`                     | Input parameter character length                                          |
| **LOWER**   | `LOWER(str)`                     | `LOWER({field})`                   | Lower case converted string of input parameter                            |
| **MID**     | `MID(str, position, [count])`    | `MID({field}, 3, 2)`               | Alias for `SUBSTR`                                                        |
| **REPEAT**  | `REPEAT(str, count)`             | `REPEAT({field}, 2)`               | Specified copies of the input parameter string concatenated together      |
| **REPLACE** | `REPLACE(str, srchStr, rplcStr)` | `REPLACE({field}, 'int', 'num')`   | String, after replacing all occurrences of `srchStr` with `rplcStr`       |
| **RIGHT**   | `RIGHT(str, n)`                  | `RIGHT({field}, 3)`                | `n` characters from the end of input parameter                            |
| **SEARCH**  | `SEARCH(str, srchStr)`           | `SEARCH({field}, 'str')`           | Index of `srchStr` specified if found, 0 otherwise                        |
| **SUBSTR**  | `SUBTR(str, position, [count])`  | `SUBSTR({field}, 3, 2)`            | Substring of length 'count' of input string, from the postition specified |
| **TRIM**    | `TRIM(str)`                      | `TRIM({field})`                    | Remove trailing and leading whitespaces from input parameter              |
| **UPPER**   | `UPPER(str)`                     | `UPPER({field})`                   | Upper case converted string of input parameter                            |
| **URL**     | `URL(str)`                       | `URL({field})`                     | Convert to a hyperlink if it is a valid URL                               |
| **REGEX_MATCH** | `REGEX_MATCH(str, pattern)`  | `REGEX_MATCH({field}, 'a.*')`      | Returns 1 if the input text matches a regular expression or 0 if it does not |
| **REGEX_EXTRACT** | `REGEX_EXTRACT(str, pattern)`  | `REGEX_MATCH({field}, 'a.*')`  | Returns the first match of a regular expression in a string |
| **REGEX_REPLACE** | `REGEX_REPLACE(str, pattern, replacer)`  | `REGEX_MATCH({field}, 'a.*', '---')` | Replaces all matches of a regular expression in a string with a replacement string |
