7 Best Google Sheets Extensions for Data & Contact Enrichment in 2026

Sales reps, recruiters, and growth teams all face the same bottleneck: a spreadsheet full of names and companies, but missing the contact details needed to actually reach out. Manually copying data from LinkedIn or bouncing between browser tabs eats hours every week.

Google Sheets add-ons solve this by bringing enrichment directly into the spreadsheet. You highlight a column, run a function, and get emails, phone numbers, job titles, or company info written back into your rows.

Below are seven extensions worth looking at, ranked by how much they actually do inside Google Sheets.

1. Derrick

Derrick is the most complete enrichment add-on available for Google Sheets. Where most tools focus on one data type, Derrick covers the entire prospecting workflow: LinkedIn import, email and phone lookup, company data, and AI-powered qualification - all from a single sidebar.

What you can do with it:

• Import leads and companies from LinkedIn Sales Navigator in one click
• Find professional email addresses from a name and company
• Find phone numbers for your prospects
• Enrich LinkedIn profiles with 80+ attributes (job title, company size, tech stack, funding rounds, skills, languages, and more)
• Look up the LinkedIn profile URL from a first name, last name, and company
• Run AI prompts at scale using Claude or OpenAI to qualify, segment, or summarize leads
• Extract emails and social profiles from any website
• Identify technologies used on a website (CRM, CMS, analytics tools)
• Deduplicate leads across tabs and clean your data

Pricing: Free plan with 200 credits/month. Paid plans start at 9 EUR/month for 4,000 credits, scaling up to 175 EUR/month for 100,000 credits. Unused credits roll over.

Why it stands out: Most enrichment tools require you to chain together three or four different services - one for scraping LinkedIn, another for finding emails, a third for phone numbers, and maybe a separate AI tool for qualification. Derrick replaces all of them. The fact that it runs natively in Google Sheets also means it connects to 3,000+ apps through Zapier, Make, or n8n without any extra integration work.

Best for: SDRs, founders, recruiters, and small sales teams that want a single tool instead of a stack.

Install: Google Workspace Marketplace

2. Hunter for Sheets

Hunter has been a staple in outbound sales for years, and their Google Sheets add-on brings three core features into the spreadsheet.

What you can do with it:

• Domain Search: Enter a company domain and get every email address Hunter has found publicly associated with it, along with confidence scores
• Email Finder: Select columns with first name, last name, and company name, and Hunter will guess and verify the professional email
• Email Verifier: Validate a list of email addresses with deliverability statuses

Pricing: Free with 25 searches and 50 verifications per month. Paid plans unlock higher volumes.

Limitations: Hunter focuses exclusively on email. There is no phone number lookup, no LinkedIn import, and no company enrichment beyond what comes attached to an email result. If you need more than emails, you will need a second tool.

Best for: Teams that only need email addresses and want a reliable, well-established provider.

Install: Google Workspace Marketplace

3. ContactSheets by ContactOut

ContactSheets takes a formula-based approach. Instead of using a sidebar, you type functions like =co_reveal() or =co_enrich() directly in your cells.

What you can do with it:

• Find verified emails and phone numbers from a LinkedIn profile URL
• Enrich profiles with name, title, company, domain, and location
• Works with ContactOut's database of 800M+ contacts

Pricing: Free to install with a free API key. Paid plans available for higher volumes.

Limitations: The formula-based workflow feels lightweight but can be harder to manage at scale compared to a sidebar with bulk actions. The tool also leans heavily on LinkedIn URLs as input - if you only have names and company info, it is less useful.

Best for: Recruiters and sales reps who already have LinkedIn profile URLs and want quick lookups.

Install: Google Workspace Marketplace

4. Dropcontact

Dropcontact differentiates itself with a strict GDPR stance: it relies entirely on algorithms and does not maintain a contact database.

What you can do with it:

• Find and verify professional email addresses
• Enrich contacts with job title, LinkedIn profile, and company info
• Clean and normalize names, job titles, and company names
• Three enrichment modes: single contact, bulk, or selected rows

Pricing: Pay-on-success model with 50 free credits to start.

Limitations: No phone number lookup. No LinkedIn import. The enrichment is solid for European markets where GDPR compliance matters, but the feature set is narrower than all-in-one tools.

Best for: Companies operating in Europe that need strict GDPR compliance and focus on email enrichment.

5. Lusha

Lusha offers a Google Sheets integration through Google Apps Script rather than a Marketplace add-on.

What you can do with it:

• Search for contacts matching your ICP filters (location, company size, industry, seniority)
• Enrich rows with verified emails, phone numbers, LinkedIn profiles, job titles, and department info
• Batch enrichment or row-by-row enrichment to control credit usage
• Automated pipelines via Zapier or Make

Pricing: Free plan with limited credits. Paid plans start at a higher price point than most competitors.

Limitations: The setup requires pasting Apps Script code and configuring an API key, which is more technical than installing a Marketplace add-on. Credit costs per enrichment tend to be higher than alternatives.

Best for: Mid-market and enterprise sales teams already using Lusha's broader platform.

6. Kaspr

Kaspr focuses on LinkedIn-based enrichment with a Chrome extension and CSV upload workflow.

What you can do with it:

• Enrich LinkedIn profiles with emails and phone numbers via Chrome extension
• Upload CSVs with LinkedIn URLs for bulk enrichment
• Connect to Google Sheets through Zapier for automated workflows

Pricing: Free plan available. Paid plans for higher volumes.

Limitations: Kaspr does not have a native Google Sheets add-on. The Google Sheets integration runs through Zapier, which adds latency and requires a separate Zapier subscription. CSV enrichment is still in beta and only supports standard LinkedIn URLs, not Sales Navigator URLs.

Best for: Individual prospectors who work primarily from LinkedIn and want quick phone numbers.

7. Snov.io

Snov.io is a broader sales automation platform that connects to Google Sheets through its API or third-party integrations.

What you can do with it:

• Find email addresses using domain search, name-based lookup, or LinkedIn search
• Verify email deliverability
• Push enriched data to Google Sheets via Integrately, Zapier, or Make
• Access company data: location, size, website, industry

Pricing: Free plan with 50 credits/month. Paid plans from $39/month.

Limitations: No native Google Sheets add-on. All integrations require external automation tools or direct API calls. This makes it harder to set up and less accessible for non-technical users.

Best for: Teams already invested in Snov.io's email automation and drip campaigns.

Quick Comparison

Bottom line

If you need a single extension that handles the full prospecting workflow - from finding a lead on LinkedIn to getting their email, phone number, and company data, then qualifying them with AI - Derrick covers more ground than any other Google Sheets add-on on this list. The free tier is generous enough to test it properly, and the paid plans stay well below what most competitors charge for similar coverage.

For teams with narrower needs, Hunter remains the go-to for email-only workflows, and Dropcontact is the safest pick for strict GDPR environments.
