Fill cells with valid test card numbers. Drops Visa, Amex or Mastercard numbers down a column — Sheets or Excel.
It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 1 credit per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.
A real example — the input you type, and the values you can pull from it. Click any cell to see the formula behind it.
Fill =VERVE("cardgenerator", "field", "brand") down a column and Generate Test Cards returns a result for every row — a batch of live values in a single drag, no code.
Add Generate Test Cards beside a table you already have to append its output right where your data lives, then sort, filter, or chart on it.
Keep the generate test cards values as formulas that look up again when their inputs change, or fill them as plain values that never move.
The same function works in both apps — install once, sign in with your key, and type it into any cell.
Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.
=VERVE("cardgenerator", "field", "brand")Same source, same arguments, same key — in Excel on desktop, the web, or mobile. Excel namespaces it as VERVE.CALL. Drag to fill a whole column.
=VERVE.CALL("cardgenerator", "field", "brand")Tune the result by adding name=value before the field argument — in any order. Leave one out and its default applies.
The brand of the card to generate
=VERVE("cardgenerator", "brand", "visa")The number of test card numbers to generate
=VERVE("cardgenerator", "count", "5")Include an AI-generated face avatar for the card owner
=VERVE("cardgenerator", "includeAvatar", "true")Return this payment gateway's documented test cards instead of generated numbers. They trigger a known outcome in the gateway's test mode
=VERVE("cardgenerator", "gateway", "stripe")With gateway: the outcome to test, such as success, declined, insufficient_funds, expired_card, incorrect_cvc, fraud or 3ds_required (Stripe). Decline scenarios are mostly Visa cards, so the brand is ignored when the gateway has none for it
=VERVE("cardgenerator", "scenario", "success")Add a field name as the last argument to land just that value in the cell.
=VERVE("cardgenerator", "field", "cards")=VERVE("cardgenerator", "field", "cards.0.cvv")=VERVE("cardgenerator", "field", "cards.0.issuer")=VERVE("cardgenerator", "field", "cards.0.id")=VERVE("cardgenerator", "field", "cards.0.number")=VERVE("cardgenerator", "field", "cards.0.expiration")=VERVE("cardgenerator", "field", "cards.0.brand")=VERVE("cardgenerator", "field", "cards.0.number_alt.masked")=VERVE("cardgenerator", "field", "cards.0.number_alt.unmasked")=VERVE("cardgenerator", "field", "cards.0.number_alt.last4")=VERVE("cardgenerator", "field", "owner")=VERVE("cardgenerator", "field", "owner.name")Premium marks data included on paid plans. On the Free plan a marked field is withheld and a marked input is ignored — either way the cell reads #PREMIUM(name) instead of a value, so a gated answer can never be mistaken for a real one.
