Copy-paste formulas for a Prospeo alternative workflow in Google Sheets
Paste a formula into row 2, test it on a few rows, then drag down to run the workflow across your spreadsheet.
Verify name-to-domain match
A: full name - B: company - C: domain
=GPT("Given name " & A2 & ", company " & B2 & ", domain " & C2 & ", suggest the most likely professional email pattern (for example first.last@domain). Label it as a guess to verify, never as confirmed.")
Clean and standardize a contact row
A: raw contact text
=GPT("Extract and clean from this text: " & A2 & ". Return full name, job title, and company in a consistent format. Mark any field not present as Unknown.")
Fit score 1-5
A: account - B: ICP - C: source text
=GPT("Score this account 1-5 for fit. Account: " & A2 & ". ICP: " & B2 & ". Source text: " & C2 & ". Return score, reason, confidence, and what to verify manually.")
Personalized opener
A: contact/role - B: signal - C: offer - D: tone
=GPT("Write a specific outreach opener for " & A2 & " based on this signal: " & B2 & ". Offer: " & C2 & ". Tone: " & D2 & ". Keep it factual and under 70 words.")
Short answer
A Prospeo alternative in Google Sheets means doing research, enrichment, scoring, and personalization with AI formulas in the spreadsheet instead of adopting a separate tool. Prospeo focuses on finding professional emails and enriching contact records. GPT for Sheets is a lighter, spreadsheet-native option for B2B sales and RevOps teams who want the research and prioritization layer where their lists already live.
Fastest path: Install GPT for Sheets -> add your source columns -> paste a formula from the formula section -> review 10 rows -> fill down the sheet.
GPT for Sheets is not affiliated with Prospeo and is not a contact database. Prospeo and other product names are trademarks of their respective owners, and the comparison here is factual and non-defamatory.
Workflow
A practical sheet for this workflow usually has these columns:
| Column | What to put there | Why it matters |
|---|---|---|
| A | Company or contact name | Stable row anchor for each record |
| B | Source notes: website copy, export, CRM fields | Keeps AI grounded in inspectable evidence |
| C | Offer or product | Sharpens relevance and scoring |
| D | Target signals to find | Defines what the AI should look for |
| E | AI research summary | First useful interpretation of the row |
| F | Fit score and label | Sorts the list for routing |
| G | Outreach opener or next action | Turns research into execution |
| H | QA flag | Stops unsupported claims before outreach |
Step-by-step setup
- Start with 10 representative rows before filling down hundreds.
- Keep raw source and export fields unchanged so you can audit the AI output.
- Run one formula to create a research summary, then inspect weak rows.
- Add constraints: max length, required format, and what to do when data is missing.
- Add a QA formula that flags missing facts and unsupported assumptions.
- Fill down once the prompt works on your sample rows.
How a Sheets workflow compares with Prospeo
GPT for Sheets adds AI research, list cleanup, scoring, and personalization directly in the spreadsheet, working on contact lists you have already sourced. It does not find or verify emails from a proprietary database - treat any email pattern it suggests as a guess to confirm with a verification tool. It does not ship a proprietary database, so pair it with your own sourced data when you need verified contact fields. It is not affiliated with Prospeo and is not a drop-in replacement for every feature; the comparison here is factual and non-defamatory.
Use cases
- List cleanup: normalize messy exported contact rows into consistent fields.
- Pattern suggestions: propose likely email formats to verify with your own tools.
- Prioritization: score and label contacts before reps invest time.
- Personalization: draft openers grounded in a specific signal.
- QA: flag rows that need manual verification before outreach.
Best for / not best for
Best for: teams that already keep contact lists in Google Sheets and want a lightweight, reviewable way to clean, research, score, and personalize without a separate platform.
Not best for: teams whose primary need is finding and verifying emails from a proprietary database; in that case use GPT for Sheets as the research and personalization layer on top of contacts sourced elsewhere.
The strongest use case is enriching and prioritizing lists you already control. GPT for Sheets supplies the AI research and QA layer; you supply lawful, sourced data.

Safety, compliance, and data quality
AI output should be treated as a draft. Use lawful public and business data only, do not rely on GPT for Sheets to reproduce a proprietary database, keep source columns visible, store source URLs or dates when relevant, and verify data before outreach. Follow consent, deliverability, and local compliance rules.
Frequently Asked Questions
Is GPT for Sheets a Prospeo replacement?
Not exactly. Prospeo finds and enriches contact emails; GPT for Sheets is a spreadsheet-native AI layer for cleanup, research, scoring, and personalization on lists you already have. Many teams use it as a lighter alternative or alongside a finder. It is unaffiliated with Prospeo.
Can it find verified email addresses like Prospeo?
No. GPT for Sheets does not include an email database or verification service. It can suggest likely email patterns from the data you provide, but you must verify them with a dedicated tool before outreach.
What does it replace and what does it not?
It replaces the manual research, cleanup, prioritization, and personalization work; it does not replace a dedicated email finder. Pair it with your sourced contacts for verified fields.
Should I trust every AI output automatically?
No. Treat output as a structured draft and use QA columns to flag missing evidence, unsupported claims, and rows that need manual verification.
