WP Post Export Import

Author: Wyarej Ali
Version: 1.1.0

A lightweight WordPress plugin to export blog posts from one site and import them into another — with author mapping, featured images, inline images, categories, and tags.

What it exports/imports

• Post titles, content, excerpts, slugs, publish dates
• Author information (with mapping on import)
• Featured images (bundled in ZIP)
• Inline content images (re-downloaded from source on import)
• Categories and tags

Installation

1. Upload the wp-post-export-import folder to /wp-content/plugins/
2. Activate via Plugins → Installed Plugins
3. Go to Tools → Post Export Import

Export

1. Choose processing mode (Batch AJAX recommended for 300+ posts)
2. Click Export Posts — a ZIP downloads automatically

Import (3-step flow)

1. Upload ZIP — upload the file and analyse it
2. Map Authors — assign each source-site author to an existing user on this site
3. Import — batch import runs with live progress and stats

Slug conflict

Posts with the same slug as an existing post are skipped.

Author fallback

If no mapping is set, posts are assigned to the site administrator.

ZIP Structure

├── posts.json           ← post data + author info + image maps
├── featured-images/     ← featured image files
└── content-images/      ← inline images from post content
