# Capitalize first letter

To capitalize the first letter in a word or string, you can use a formula based on the LEFT, MID, and LEN functions. In the example shown, the formula in C5 is:

### How this formula works

The first expression uses LEFT and UPPER to capitalize the first letter:

No need to enter 1 for num_chars in LEFT, since it will default to 1. The second expression extracts the remaining characters with MID:

The text comes from B5, the start number is hardcoded as 2, and num_chars is provided by the LEN function. Technically, we only need to extract (length - 1) characters, but MID won't complain if we ask for more characters, so we've left things in the simplest form.

### Lowercase the rest

If you want to lowercase everything but the first letter, just wrap the second expression in the LOWER function:

The LOWER function will force all remaining characters to lower case.
