# Pair functions

> Learn how to use and combine different pair functions in APL

Use pair functions to create, parse, and search key-value pair strings. These functions are useful for working with tags, labels, metadata, and any data stored in key-value format.

## List of functions

| Function                                                       | Description                                                                                                  |
| -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ |
| [find\_pair](/apl/scalar-functions/pair-functions/find-pair)   | Searches an array of key-value pairs and finds the first pair that matches specified key and value patterns. |
| [pair](/apl/scalar-functions/pair-functions/pair)              | Creates a dynamic object representing a key-value pair.                                                      |
| [parse\_pair](/apl/scalar-functions/pair-functions/parse-pair) | Parses a pair string into its key and value components.                                                      |
