Bulk Blog Uploader Plugin for Squarespace
Squarespace Doesn't Have a Bulk Blog Import.
Well it does with an XML import, but it’s quite slow and hard to use.
Import hundreds of blog posts to Squarespace 7.0 or 7.1 from a spreadsheet, Notion, or JSON. Review, edit, and push them live from inside your admin panel.
No external tools. Just upload and go.
The Blog Bulk Import Uploader lets you import up to 1,000 blog posts to Squarespace 7.0 or 7.1 from XLSX, CSV, JSON, Notion exports, or Google Sheets.
Upload your content, review and edit posts in a built-in editor, then push them live directly from your Squarespace admin. Import and edit titles, content, slugs, categories, tags, authors, featured images, publish dates, and statuses before pushing posts live. Built-in validation checks and bulk actions help you review and manage content before publishing.

Why Squarespace Blog Migration Is Still Painful
You already know this. A client has 300 blog posts on WordPress, or a content team hands you a spreadsheet of 80 articles, and Squarespace expects you to create each one individually. Title, content, slug, categories, tags, featured image, status. Save. Next.
The built-in WordPress importer is fragile and only handles one format. Third-party tools want you to set up API credentials, install browser extensions, or pay monthly for something you'll use twice a year.
This tool exists because there should be a simple way to bulk import blog posts to Squarespace. So we built one that runs right where you already work: inside the admin panel.
