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."

Numbers from a real small firm that shared their stats. Yours will differ, but gains like this are common once noise is gone.

Quick safety notes

  • Strip all personal data you do not need before upload.
  • Never paste credit card or medical info.
  • Pick an AI tier that lets you keep data private.

Wrap‑up

Clean data powers every channel. ChatGPT cuts hours to minutes. Tag smart. Segment tight. Ship quick. Learn and repeat. Growth follows.

Frequently Asked Questions

1. Can free ChatGPT do file work?

2. How often should I refresh tags?

Review spend tags each quarter or after major sales spikes.

3. What if my email tool blocks CSV import?

Convert to XLSX or use the tool’s copy‑paste upload option.

4. Does ChatGPT fix encodings?

Yes. Add a prompt line: "Convert file to UTF‑8." It will re‑encode.

5. How do I spot spam traps?

Ask ChatGPT to mark domains in known trap lists. Always confirm with a specialist service.

6. Can I run this for SMS lists too?

Same flow works. Swap email column for mobile and obey SMS rules.

7. What if I lack spend data?

Use signup date and open history to tag interest levels instead.
