If your TYPO3 installation is using Composer, install the import/export extension by:
composer require typo3/cms-impexp
If you are using Composer and not working with the latest version of TYPO3 you will need to add a version constraint:
composer require typo3/cms-impexp:"^10.4"
Installing the extension prior to version 11.4¶
Before TYPO3 11.4 it was still necessary to manually activate extensions installed via Composer using the Extension Manager.
If you are using TYPO3 with Composer and are using a version of TYPO3 that is older than 11.4, you will need to activate the extension:
Access Admin Tools > Extension Manager > Installed Extensions
Activate the extension by selecting the Activate button in the column labeled A/D
If you are working with an installation of TYPO3 that doesn't use Composer, this
extension will already be part of the installation due to the fact that
.zip packages come bundled with all system extensions.
However, whilst the extension is already downloaded, it is likely that the extension is not activated.
To activate the import/export tool, navigate to Admin Tools > Extension Manager > Installed Extensions and search for "impexp". If the extension is not active, activate it by selecting the Activate button in the column labeled A/D.
Admin rights are required to activate the extension.
