# Utils

Functions in the **Utils** category of the Studio `fx` menu handle everyday string, filter, escape, and conversion
tasks.

Start with the utilities you use most often:

- [Find / Replace](./find-replace/) — replace matches in the input (including regex options).
- [Filter](./filter/) — keep or drop lines that match a condition.
- [Trim](./trim/) / [Remove whitespace](./remove-whitespace/) — clean surrounding or internal whitespace.
- [Head](./head/) / [Tail](./tail/) — take the first or last lines.
- [Escape string](./escape-string/) / [Unescape string](./unescape-string/) — escape or restore special characters.

Common reshape and convert helpers:

- [Sort](./sort/) / [Unique](./unique/) / [Reverse](./reverse/) — reorder or deduplicate delimited values.
- [Count occurrences](./count-occurrences/) — count how often a string appears.
- [Convert data units](./convert-data-units/) / [Convert distance](./convert-distance/) — unit conversion.

Open a function page from the sidebar for parameters, returned values, and examples. The transform functions overview
also summarizes this category.
