Detect Bots in Google Sheets
Formula
Flag bot and crawler user agents by the row. =VERVE("botdetector", A2) returns bot name, category and reputation — Sheets or Excel.
=VERVE("botdetector", A2)=VERVE.CALL("botdetector", A2)A2 holds the ua you're looking up. Drag the formula down and each row resolves on its own.
With literal values
Nothing has to come from a cell — typed values work the same way.
=VERVE("botdetector", "Googlebot/2.1 (+http://www.google.com/bot.html)")Inputs
Required inputs are positional, in the order below. Everything else is passed as a "name", value pair after them — the same shape as SUMIFS.
| Input | Type | Where it goes | Description |
|---|---|---|---|
uaRequired | string | argument 2 | The user agent string to analyze (URL encoded) (e.g. Googlebot/2.1 (+http://www.google.com/bot.html)) |
What lands in your sheet
With no "field" pair the formula spills the whole response as two columns — field name on the left, value on the right — starting at the cell you typed in. Make sure the cells below and to the right are empty.
Pulling one value
Add a "field" pair to get a single cell back instead of a table. The field name is the dot-path from the table below.
=VERVE("botdetector", A2, "field", "userAgent")=VERVE.CALL("botdetector", A2, "field", "userAgent")Available fields
#PREMIUM(field) rather than a value, so a locked field never looks like a real answer.| Use as "field" | Type | Example cell value | Description |
|---|---|---|---|
userAgent | string | Googlebot/2.1 (+http://www.google.com/bot.html) | The analyzed user agent string provided in the request |
isBot | boolean | true | Whether the user agent belongs to a known bot or crawler |
botPremium | object | {…} | Detailed bot information including name, category, and reputation |
bot.name | string | Googlebot | Name of the detected bot or crawler |
bot.category | string | search_engine | Category of bot: search_engine, social_media, monitoring, seo_tool, scraper, other |
bot.url | string | http://www.google.com/bot.html | Official URL or documentation link for the bot |
bot.reputation | string | trusted | Trust level: trusted (search engines, social), neutral (monitoring, SEO), malicious (scrapers, spam), or unknown |
bot.shouldBlock | boolean | false | Recommendation whether to block this bot based on category and reputation |
isAutomatedPremium | boolean | true | Heuristic signal that the traffic is automated — true for known bots, missing user agents, and clients that do not present as a standard browser (e.g. curl, scripts, headless tooling). Catches automated clients not in the bot database |
riskScorePremium | number | 0 | Composite 0-100 risk score combining bot reputation, block recommendation and automation heuristics (higher is riskier) |
riskLevelPremium | string | low | Risk band derived from the score: low, medium or high |
Filling a whole column
Hand the first argument a range instead of a cell and the add-in makes one batched call for the lot, then spills the answers down. That is faster than dragging the formula and costs the same credits — one per row looked up.
=VERVE("botdetector", A2:A100, "field", "userAgent")=VERVE.CALL("botdetector", A2:A100, "field", "userAgent")A2:A100 is the column of ua values. The result spills down alongside it, one row per input, blanks skipped.
When a cell doesn't fill
A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() won't catch it; test with LEFT(cell, 4) = "#ERR" instead.
| Cell reads | What happened |
|---|---|
#ERR Not connected | No API key saved. Open the side panel and connect your account. |
#ERR Replace <name> with a cell or value | The preview formula was copied as-is. Swap the placeholder for a cell reference. |
#ERR No "x" in botdetector | An option name that this source doesn't take. The message lists the ones it does. |
#ERR No data point "…" | The "field" path isn't in the response. Check the dot-path against the table above. |
#PREMIUM(field) | The field exists but your plan doesn't include it. |
#ERR Out of credits | The month's credits are spent. Usage resets on your billing date. |
Before the formula works
The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet doesn't leak it and a collaborator without access simply sees the last calculated values.
- Install the add-in for Google Sheets or Excel.
- Open the side panel and sign in, or paste a key from your dashboard.
- Type the formula above into any cell.

Frequently asked questions
Does Detect Bots in Google Sheets work in both Google Sheets and Excel?
Yes — the same source, the same arguments. Sheets calls it =VERVE("botdetector", …) and Excel calls it =VERVE.CALL("botdetector", …); that function name is the only difference.
Do the cells recalculate on their own?
They recalculate when the sheet does — on edit, on open, or on a manual recalc. Each recalculation is a fresh call and spends credits, so for a large static column it's worth copying the results and pasting them as values.
How many credits does a filled column cost?
1 credit per row looked up, whether you drag the formula or pass a range. The range form is one HTTP call instead of many, but the credit count is the same.
Can I share the sheet without sharing my key?
Yes. The key is stored against your account, not in the file. Collaborators see the values already in the cells; formulas only recalculate for someone who has connected their own account.
Why is a cell showing #ERR instead of an error?
So you can read the reason. Excel can't display a custom message on a real spreadsheet error, so the add-in returns the explanation as text on both platforms instead.
