Tired of manually posting to Reddit from your content calendar? This tutorial shows how to build an automated Reddit posting workflow in Needle that reads from Google Sheets and publishes posts on schedule.

Overview

The workflow automatically reads your Reddit posting schedule from Google Sheets and submits posts to designated subreddits—turning your spreadsheet into a powerful Reddit automation tool.

Key Actions

1. Scheduled Trigger – Runs hourly to check for posts ready to publish
2. Google Sheets Reader – Fetches post data including title, content, subreddit, and schedule
3. Time-Based Filtering – Identifies posts that are due for publication
4. Reddit Submission – Automatically posts to the specified subreddit
5. Status Tracking – Updates Google Sheets with post URL, timestamp, and status

What You'll Need

• Google Sheet – A spreadsheet with columns for: Title, Content, Subreddit, Scheduled Time, Status, Post URL Tip: Use datetime format for scheduling (e.g., "2025-10-01 14:00")
• Reddit Account – With verified email and sufficient karma for posting
• Subreddit Access – Ensure you can post to your target communities

How It Works

Every hour, the workflow:

1. Reads all rows from your Google Sheets posting calendar
2. Filters for posts where:
   • Scheduled time has passed
   • Status is "Pending" or "Ready"
3. For each qualifying post:
   • Submits to the specified subreddit
   • Captures the Reddit post URL
   • Updates status to "Posted"
   • Records actual posting timestamp
4. Handles errors gracefully (e.g., rate limits, invalid subreddit)
5. Logs any failures back to Google Sheets for manual review

Wrap-up

With this Needle workflow, you can manage all your Reddit posting from a simple Google Sheet, schedule content in advance, and ensure consistent community engagement without manual intervention—ideal for community managers and content teams running multi-subreddit strategies.
