Buffer Bulk Post Scheduler from Spreadsheet

WHAT IT DOES

Buffer Bulk Post Scheduler from Spreadsheet lets you schedule multiple posts from spreadsheet data in a single operation. Instead of manually copying each post from a spreadsheet into Buffer's compose box, setting the time, selecting channels, and scheduling — repeating this for every single post — this tool provides a unified checklist of all posts parsed from your spreadsheet data. You can filter posts by channel or date to quickly find the ones you want to schedule. Select any number of posts using checkboxes, optionally choose a target channel from the dropdown, and click Schedule. The tool then automatically processes each selected post — opening the compose or scheduling modal, setting the content, selecting the channel, and confirming the schedule. This turns what could be dozens of manual operations into a single batch action, making social media content publishing significantly faster and more efficient.

WHERE IT RUNS

This script runs exclusively on the Buffer web application in your browser. It activates on the queue page, compose view, and publish dashboard where posts can be scheduled. It requires the BotGentz extension to inject and execute the script. The tool does not work on the Buffer mobile app, the API, or any third-party Buffer clients — only the web-based Buffer interface accessed through a Chromium-based or Firefox browser. It specifically targets pages under *.buffer.com, including the Buffer queue, publish, and compose views.

HOW TO USE

After installing the script via BotGentz, navigate to your Buffer dashboard and open the queue, publish, or compose page. The tool automatically detects posts from the current view — typically from a spreadsheet import or the compose interface — and displays a floating panel on the right side. The panel shows all posts on the current page, with checkboxes next to each post entry. Each post displays its content preview, scheduled time, and target channel. Use the search box to filter by content, or use the channel filter dropdown to show only posts for a specific social media channel. Check the boxes for every post you want to schedule. Below the post list, optionally select a target channel from the dropdown — this overrides the default channel for selected posts. Click "Schedule Selected" and confirm the action. The tool will process each selected post one by one — opening the schedule modal, setting the content, selecting the channel if provided, and confirming. A status message appears when the operation completes, showing how many posts were successfully scheduled.

THE ACTUAL MECHANISM — WHY IT WORKS

Buffer's web interface is built with React and uses a component-based rendering system for its post management. The post list is rendered as cards or list items, each containing post metadata and action buttons. This tool scans the DOM for post items using multiple selector patterns that Buffer consistently uses across versions. For each post, it extracts the content, scheduled time, and channel information from the visible text content and data attributes. Each post is assigned a unique identifier from data attributes or checkbox values. When scheduling, the tool locates the schedule button within each post item or accesses it through the action menu. The tool then opens the scheduling modal, sets the content, selects the target channel if specified, and clicks the confirm button. The tool uses React-friendly event dispatching — setting values via the native setter and dispatching both "input" and "change" events to ensure React registers the updates. This approach works without making direct API calls, which would require authentication credentials and knowledge of Buffer's internal API structure. By using the existing UI, the tool works within Buffer's own permission and validation system, and continues to function even if the underlying API changes.

THE PANEL

The floating panel is fully draggable — click and drag the header to reposition it anywhere on the page. The panel's position is saved per site in localStorage, so it reappears exactly where you left it when you return to the queue page. Double-click the header to snap the panel to the nearest edge (left or right). A collapse button minimizes the panel to a small tab showing a calendar emoji badge, keeping it out of the way while still accessible. The post list inside the panel is scrollable and resizes vertically based on the number of posts. Pressing Escape while the panel is focused closes it completely; reopening is done via a small button injected near the page toolbar. All panel interactions are non-blocking — Buffer's main UI remains fully responsive while the panel is open, and the panel updates automatically when you navigate between pages.

PLEASE NOTE

This script requires the BotGentz extension (free) to run user scripts on Buffer. Buffer frequently updates its web interface and modal structures; if the tool stops working, check for an updated version within BotGentz's script repository. This tool does not store, transmit, or log any post content, scheduling data, or channel information — all operations occur locally in your browser with no external network requests except those made by Buffer itself. Scheduling actions are applied through Buffer's own UI event system, so all changes respect your account permissions and posting limits. The tool does not bypass Buffer's security or permission system; it simply automates the clicks you would otherwise perform manually. For accounts with a large number of posts, the tool may take several minutes to complete the operation, as each post is processed sequentially with delays to avoid overwhelming the UI. A progress indicator shows which post is currently being processed. Always double-check your selections and channel choice before applying changes, as scheduling many posts can affect your social media calendar. The tool only affects posts visible on the current page; to schedule all posts, use Buffer's built-in pagination controls or adjust your filters to show all relevant posts. The channel dropdown is populated from channels detected on the page; selecting a channel will override the default channel for scheduled posts.
