Microsoft ExcelAdd-in

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.

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. Everything unmarked works on every plan. Compare plans

Validate ISBNs, answered

Everything you need to wire it into a sheet.

How do I pull Validate ISBNs into Google Sheets?
Install the VerveSheets add-on, sign in once with your key, and type =VERVE("isbnvalidator", "978-0-306-40615-7", "field", "valid") into any cell. The "field" argument names the value you want back, so the cell resolves to a single number or string you can chart, sort, or feed into another formula.
What data can I pull from Validate ISBNs?
Validate ISBNs returns valid, type, normalized, checksum_valid and prefix, plus 4 more — name any one of them as the "field" argument and that value lands in the cell. Leave the field out and the whole record spills into a two-column table instead.
Which Validate ISBNs fields need a paid plan?
formatted and check_digit are included from the Starter plan up. On the Free plan the cell returns #PREMIUM(field) rather than a wrong or empty value, so it's always obvious which one to upgrade for. Every other field works on Free.
Can I fill a whole column of Validate ISBNs at once?
Yes. Put your isbn values down a column and point the formula at the range — A2:A50 instead of A2 — and one call returns a value for every row. Dragging the formula down works too, but the range form is a single billed call per column rather than one per cell.
How many credits does each Validate ISBNs cell cost?
Each resolved cell costs 1 credit. A cell only re-bills when it actually refreshes, so a sheet you aren't touching doesn't keep charging.
Does Validate ISBNs work in Excel as well as Google Sheets?
Yes — same arguments, same key, same fields. Excel namespaces custom functions, so the call is =VERVE.CALL() there and =VERVE() in Google Sheets; nothing else about it changes.

Put Validate ISBNs in your next spreadsheet. Add the extension, paste the formula, and the cell keeps itself current.
