# LOWER

Converts all letters in the specified text string to lowercase. Any characters that are not letters are unaffected by this function. Locale rules are applied if a locale is provided.

## Use

`LOWER(text, [locale])` and replace text with the field or text you wish to convert to lowercase, and locale with the optional two-character ISO language code or five-character locale code, if available.

![MYCOMPANY.COM Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/images/icon_example.png)

MYCOMPANY.COM Example

`LOWER("MYCOMPANY.COM")` returns “mycompany.com.”

![Ticker Symbol Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/images/icon_example.png)

Ticker Symbol Example

`LOWER(TickerSymbol)` returns the text in Ticker Symbol in lower case characters.

Turkish Language Locale Rules Example

The Turkish language has two versions of the letter “i”: one dotted and one dotless. The locale rules for Turkish require the ability to capitalize the dotted i, and allow the dotless I to be lowercase. To correctly use the `LOWER()` function with the Turkish language locale, use the Turkish locale code `tr` in the `LOWER()` function as follows:

`LOWER(text, "tr")`

Using this locale code ensures that Salesforce doesn’t transform any dotted i in the text to a dotless I.
