# Deactivating Automatic Changes

By default, LibreOffice automatically corrects many common typing errors and applies formatting while you type. You can immediately undo any automatic changes with Command Ctrl+Z.

The following shows you how to deactivate and reactivate the automatic changes in LibreOffice Calc:

## Automatic Text or Number Completion

When making an entry in a cell, LibreOffice Calc automatically suggests matching input found in the same column. This function is known as AutoInput.

To turn the AutoInput on and off, set or remove the check mark in front of Tools - AutoInput.

## Automatic Conversion to Date Format

LibreOffice Calc automatically converts certain entries to dates. For example, the entry 1.1 may be interpreted as January 1 of the current year, according to the locale settings of your operating system, and then displayed according to the date format applied to the cell.

To ensure that an entry is interpreted as text, add an apostrophe at the beginning of the entry. The apostrophe is not displayed in the cell.

## Quotation Marks Replaced by Custom Quotes

## Cell Content Always Begins With Uppercase

Choose Tools - AutoCorrect - AutoCorrect Options. Go to the Options tab. Unmark Capitalize first letter of every sentence.

## Replace Word With Another Word
