Altcoin News to LinkedIn Posts with DeepSeek AI & Google Sheets

This n8n workflow automates the process of finding the latest altcoin news, summarizing it using DeepSeek AI, and then posting these summaries to LinkedIn, with a record kept in Google Sheets. It helps you stay updated with cryptocurrency news and maintain an active professional presence without manual effort.

What it does

Triggers on a Schedule: The workflow starts at regular intervals (e.g., daily, hourly) to check for new news.
Fetches Altcoin News: It reads the latest articles from a specified RSS feed related to altcoin news.
Filters for New Articles: It compares the fetched articles against a Google Sheet to ensure only new, unposted articles are processed.
Generates AI Summaries: For each new article, it uses DeepSeek AI to generate a concise summary suitable for a LinkedIn post.
Posts to LinkedIn: The AI-generated summary is then published as a new post on your LinkedIn profile.
Logs to Google Sheets: After successfully posting to LinkedIn, the article details (including the generated summary and post URL) are recorded in a Google Sheet, preventing duplicate posts and providing a historical log.
Introduces Delays: A "Wait" node is included to introduce a delay between processing each article, preventing rate limiting issues with APIs.

Prerequisites/Requirements

n8n Instance: A running n8n instance.
Google Sheets Account: A Google account with access to Google Sheets. You'll need to create a spreadsheet to store the news articles and their LinkedIn post status.
LinkedIn Account: A LinkedIn account where the posts will be published.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields.
