Tomba for Microsoft Excel
Find and verify email addresses without leaving Excel. Our add-in brings Tomba's power to your spreadsheets.
// 01 · in the pane
Every tool, right inside Excel
Finders, verification, enrichment, Reveal and the tech stack, from one pane. Each tool shows what a run costs before you start, and writes its answers to new columns or a new worksheet: what you had stays as it is.
Sign in once, see every credit
Your search and verification credits left, always in view, and a quick way into each tool. Search and verification credits are separate balances.
Every email at a company, in one search
Type a domain: names, roles, departments, LinkedIn, scores and sources land in a new worksheet. Or run it on a whole column of domains. Charged only when an address is found.
Names in, verified emails out
Map a first name, a last name and a domain (or a full name, or a company) and Tomba finds each person's address, with its score, sources and status in new columns.
Catch bad emails before you send
Verify a whole column in one click: the status and the score are written next to every address. It uses verification credits, not search credits.
Phone numbers for each row
From an email, a website, a domain or a LinkedIn profile: up to ten numbers per row, with the line type, carrier and time zone. Charged only when a number is found; 1 credit when the row has a domain.
The person behind each address
Names, LinkedIn, score, verification status and the company for each email of a column. Company Enrichment does the same for a column of domains.
Build company lists in one search
Describe your market in a sentence or set filters: industry, size, location, revenue, technologies. Reveal writes the companies to a new worksheet, up to 50 per page.
See the tech stack behind every website
The technologies on each website of a column, by category. Not charged: it needs a positive search balance. Similar Domains turns one customer into a lookalike list the same way.
// 02 · functions
Every Excel function is an API call
Type =TOMBA. in any cell: each function calls the endpoint beside it with your Tomba account and costs what that endpoint costs. Answers are saved for a while, so recalculating a sheet does not repeat the lookups.
| Function | Endpoint | Cost |
|---|---|---|
=TOMBA.DOMAIN_SEARCH(domain, limit) | GET/domain-search | 1 search credit per 10 results |
=TOMBA.FIND_EMAIL(full_name, domain) | GET/email-finder | 1 search credit |
=TOMBA.FIND_EMAIL_SPLIT(first_name, last_name, domain) | GET/email-finder | 1 search credit |

// 03 · whole columns
A thousand rows, one run
Run a tool on a whole column, up to 1,000 rows at a time. The pane shows the progress and the time left, waits when your plan's rate limit is reached, then goes on.
- It runs in the pane
- Keep the pane open while it runs; closing it stops the run, and Tomba offers to resume next time.
- Nothing is overwritten
- Answers go to new columns or a new worksheet. Your own columns stay as they are.
- A credit breakdown first
- Every tool shows what it is charged for before you start, and failed lookups are not charged.
