How Google Sheets + Zapier + ChatGPT can write, schedule, and publish LinkedIn posts—without code, without burnout.

If you’re on LinkedIn (and let’s be honest—you are), you know the struggle: great ideas, scribbled notes, voice memos… and zero time to turn any of it into well-made posts. As Chrissy Clary says in a recent video, “You’ve got the idea. But finding the time to turn your ideas into a well-written post that can be published can be a total energy drain.” In that clip (and throughout Interact Digital’s own work), she outlines a pragmatic fix: an automated pipeline that drafts and posts LinkedIn content using Google Sheets, Zapier, and AI—managed with a human touch.

Below is a practical, journalistically minded how-to: the why, the exact setup, prompt recipes, guardrails to keep your voice human, and tips to test and scale.

Why automate LinkedIn posting (and why responsibly)

Automation is not a shortcut to laziness—it’s a route to consistency. When your best ideas remain half-finished notes, they never gain momentum. Automating the mechanical steps (drafting a first pass, scheduling, posting) frees you to add the human layer where it matters—strategy, nuance, and final edits.

A note of caution: automation should amplify your voice, not replace it. Keep a human review step for posts that represent your personal brand or a client’s profile. And always follow LinkedIn’s terms of service and best practices—no spammy mass-posting, please.

What you’ll need (quick checklist)

• A Google account + Google Sheets

• A Zapier account (free tier works for basic automations)

• Access to OpenAI / ChatGPT in Zapier or another generative AI step (or a step that calls an AI API)

• A LinkedIn profile or LinkedIn Company Page admin access (to post)

• A simple editorial workflow and one teammate (or you) to review

The Google Sheet: your content cockpit

Create a Google Sheet to house raw ideas and publish-ready drafts. Here’s a suggested column layout:

• ID — unique row ID

• CreatedDate — auto timestamp

• Author — who owns the idea

• RawIdea — quick note or voice memo transcript

• Topic — 1–3 word tag (e.g., "email marketing")

• Tone — (e.g., witty, professional)

• Draft — AI-generated post (output goes here)

• CTA — call to action (e.g., “Read the guide”, “Book a call”)

• Status — Idea / Drafted / Review / Scheduled / Posted

• ScheduledTime — desired publish datetime (ISO format)

• LinkedInURL — populate after posting

This single sheet serves as both a backlog and a content queue. Use Status to trigger Zap actions—only process rows set to Drafted → Review or Scheduled.

Build the Zap: step-by-step

Below is a typical Zapier workflow that turns a sheet row into a polished LinkedIn post.

Trigger – New or Updated Spreadsheet Row (Google Sheets)

Zap watches the sheet and fires when Status changes to Drafted (or Ready).

Action 1 – Call ChatGPT (OpenAI app in Zapier) to Draft

Send a prompt with your RawIdea, Topic, and Tone, and ask ChatGPT to produce a LinkedIn-friendly post (max ~1300 characters) with an opening hook, body, and CTA. Example prompt below.

Action 2 – Update Spreadsheet with Draft

Write the AI output back to the Draft column and flip Status to Review.

Optional Action 3 – Slack/Email Notification for Human Review

Ping the content owner to review the draft. They can edit the Draft cell directly in Sheets.

Action 4 – Scheduling / Wait Step

When Status becomes Scheduled and ScheduledTime is populated, Zapier’s “Schedule by Zapier” or a delay-until step waits until publish time.

Action 5 – Post to LinkedIn

Zap utilizes the LinkedIn integration to create a post on either a personal or company profile. Map the Draft cell to the post copy and add image URLs if required.

Action 6 – Update Spreadsheet

Write back the LinkedInURL returned by LinkedIn and set Status to Posted.

That’s it—no code, full loop.

Example ChatGPT prompt (copy-paste ready)

Use this prompt when calling ChatGPT in Zapier. Swap variables in curly braces for sheet values.

This structure forces the AI to deliver a usable draft and an image suggestion for the designer.

Crafting prompts that keep the voice human

• Provide concrete constraints (length, emoji allowance, hashtag).

• Add a short example of "how you speak" in the prompt if your brand voice is unique (two sample lines).

• Ask the AI to include a signature phrase or the founder’s point of view to keep consistency.

• Use the “suggest image” line so visuals remain consistent and not generic.

Example: “Write like a consultant who drinks terrible coffee but loves good strategy—use small humor, not sarcasm.”

Images, links & hashtags

Zapier can attach image URLs to posts. Store image URLs in your sheet (or point to a shared drive) and map them into the LinkedIn action. For richer visual posts, humans should approve the image. Hashtags should be tailored—limit to 1–3 hashtags per post for LinkedIn.

Testing, debugging & safety

• Run the Zap in test mode with a private test sheet and a test LinkedIn account.

• Verify character limits (LinkedIn truncates long posts; keep under ~1,300–1,500 chars to be safe).

• Keep a log: add columns for ZapRunTime, Error, and RetryCount.

• Rate limits: If you post too quickly across many accounts, LinkedIn may flag your activity. Stagger schedules and avoid mass automation for newly created accounts.

Workflow tips for quality control

• Human-in-the-loop: always have a reviewer for client profiles or founder posts. Use Status to force manual approval.

• Batch review: review drafts in batches to save cognitive overhead.

• Monthly audits: review top-performing posts and refine prompts accordingly.

• Voice bank: maintain a short file with sample lines/phrases to feed ChatGPT (keeps tonality consistent).

Measuring success

Track these KPIs in a companion sheet or dashboard:

• Impressions and engagement per post (likes/comments/shares)

• Click-throughs from CTAs

• Time-to-publish (idea → posted)

• Percentage of AI drafts accepted as-is vs. edited.

If you do A/B tests (two hooks, same post), note which hooks perform better and roll those learnings back into your prompt library.

Legal & ethical guardrails

• Don’t auto-post client-sensitive info.

• Avoid posting content that claims misleading expertise—always be truthful.

• Respect data privacy if your prompts include customer data.

• If using client credentials, secure tokens via Zapier and rotate them if staff change roles.

Bring in the Content Beast (if you want to scale)

As Chrissy Clary explains, Interact Digital built a larger system called the Content Beast—“the heart of an AI assistant… corralled by a team of strategists, editors, videographers, designers” to move content from ideation to publication. The DIY Zap + ChatGPT pipeline is ideal for individuals and small teams; the Content Beast is the managed option for those who require end-to-end production at scale.

Final word: automation ≠ abdication

Automating LinkedIn posting is smart; automating quality control isn’t. Treat automation as a draft engine and cadence keeper, not a replacement for human judgment. Use Google Sheets as the single source of truth, Zapier to stitch processes together, and ChatGPT to accelerate drafting—then add your edits, warmth, and authority before you hit publish.

As Chrissy says in the video, “This is perfect whether you’re managing your own brand or if you’re juggling a few clients.” Build the system once, keep the human in the loop, and free the energy you’d otherwise spend on the mechanics—so you can write the posts that actually move people.
