This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



ImpEx is a WordPress plugin that allows you to import and export data from and to your WordPress installation.

The primary goal for ImpEx is to provide a true Open Source WordPress Plugin for importing/exporting your WordPress data (including data from third-party plugins/themes).

This plugin is in an early (but working) stage.

Impex provides :

  • WordPress hooks for third-party plugins to expose their own data to ImpEx Import / Export without being dependent on Impex.

  • a (semi) streaming architecture for large data exports/imports.

  • Definition of configurable import/export profiles defining data providers to use and configuration of these data providers

    • A user interface for importing / exporting data via ImpEx WP admin screen
  • the ImpEx API is designed to support resumable/cancelable imports and exports.

  • ImpEx provides a REST API integrated into WordPress

  • ImpEx is explicitly designed for use in managed WordPress instances

  • ImpEx development relies heavily on PHP unit testing its feature set to be stable and consistent.

  • a CLI for importing/exporting data via ImpEx REST interface.
    The ImpEx CLI can be used as an alternative to the ImpEx WP admin screen.

  • related NPM package @cm4all-wp-impex/generator enabling transformation of any content to Impex Export format.

    Using this package you’re able to convert any content to WordPress and import it using the ImpEx plugin. See the Tutorial
    or watch the walk-trough at YouTube.

Your help is welcome !!

Impex uses modern browser features as building blocks.

Right know some of them might not be available in some browsers :

  • File System Access API to export and import data to the local filesystem. This browser feature is mandatory.

    Right now Chromium based browsers (except of Brave who disabled this feature) and Safari supporting the File System Access API.

    As of now, it’s unclear if and when Firefox will support the File System Access API.

    As an alternative you can use the ImpEx CLI to trigger import/export operations on the commandline.

  • Depending on your browser version the Crypto API feature we use (window.crypto.randomUUID) may not be supported by your browser.

    As of now, all «green» browser support it.

    But if you use an older version of a browser it might happen that Impex will not work since the browser feature is not available in your browser.

Where can I find the ImpEx documentation ?

Documentation available at the Impex plugin GitHub pages

Please file bugs and feature requests at the Impex plugin GitHub issues

Why ImpE written in PHP 8 ?

Because PHP 8

  • is much faster than any previous PHP Version

  • allows a much cleaner PHP code

The plugin version available here (at WordPress plugin directory) is transpiled down to PHP 7.4

If you prefer to use the PHP 8 version, you can download it from the ImpEx WordPress plugin GitHub repository

What’s the current feature set ?

  • ImpEx provides right now generic providers for

    • import/export WordPress posts/pages including attachments/uploads and custom post types

    • import/export configurable database tables (can be used export data from third party plugins/themes)

    • import/export configurable wp_options (can be used export data from third party plugins/themes)

  • ImpEx imports and exports data as plain files directly to your local filesystem so that you can operate on the exported data (and attachments) without hassle.

  • ImpEx supports snapshots to allow you to rollback to a previous state of your data without downloading the whole data to your local machine

What’s planned for the future ?

  • an intuitive user interface allowing to configure import/export profiles and configuration of the used data providers based on React and JSON Schema

  • monthly releases
