Uploading content to multiple WordPress sites individually is tedious and error-prone, especially when managing large networks. The MainWP Article Uploader Extension eliminates this bottleneck by allowing you to upload multiple articles across all your connected child sites in one go. It supports plain text files and CSV uploads, letting you specify titles, slugs, categories, tags, and even HTML content. You can also assign authors, add excerpts, and format posts using built-in HTML support. This extension is ideal for streamlining content delivery, and when used with the Post Dripper Extension, it enables scheduled publishing for ongoing site activity.
