Boost Marketing with ChatGPT: Spreadsheet Cleanup and Customer Segmentation
Table of Contents
Why spreadsheets slow growth
Messy rows hide real fans. Typos waste ad spend. One marketer at an agency fixed this in an hour with ChatGPT. Subscriber count jumped. Targeting got crisp.
What you need
- CSV exports from store, CRM, finance tool
- ChatGPT Plus or any model that reads files
- LibreOffice or Excel for quick checks
- Email platform that accepts tags
Step 1. Gather every list
Pull data from checkout, newsletter, event tool. Save as UTF‑8 CSV. Keep headers clear: email, first_name, last_name, spend_total, signup_date.
Step 2. Remove clashes
Drag all files into one ChatGPT chat. Paste this prompt:
Merge these CSV files.
Keep header names.
Remove rows with blank or invalid email.
Deduplicate on email.
Spell‑check first and last names.
Add a status column: active, bounced, unsub.
Download the new file it returns. Spot‑check ten random rows in Excel. Looks fine? Move on.
Step 3. Tag and score
Next prompt:
Add a tag column based on spend_total
spend_total >= 500 => VIP
spend_total 100‑499 => Warm
spend_total < 100 => New
Return full sheet.
Ask ChatGPT to add an LTV score 1‑5 too. This will fuel smarter segments.
Step 4. Import and test
Upload sheet to your email platform. Build three segments: VIP, Warm, New. Draft one plain email. Change offer by segment. Send to a five percent test slice first. Watch open rate and clicks.
Step 5. Loop ideas
Export campaign report. Drop CSV back into ChatGPT. Prompt:
Give me three actions to lift clicks on next send.
Point to subject line, send time, or offer mismatches.
Extra prompt ideas
- "Flag emails that look like role accounts such as info@."
- "Create a column called last_active with days since last open."
- "Suggest subject lines for VIP group based on past wins."
