Generate CUIDs

Overview

Cuid Generator works by combining multiple components: a timestamp for sorting, a counter for same-millisecond uniqueness, a process fingerprint for distributed systems, and random data for collision resistance.

Formula

One function covers the whole catalog: the first argument names the source, the rest are its inputs, and the "field" pair says which single value lands in the cell. Formulas covers the grammar that applies to all of them.

=VERVE("cuidgenerator", "field", "cuids")

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. Premium inputs are accepted on every plan but only take effect on plans that include them.

Input	Type	Where it goes	Description
`count`Optional	integer	"count", value	Number of Cuids to generate default 1 · range 1–100

Passing an option

=VERVE("cuidgenerator", "count", 10)

What lands in your sheet

The "field" pair is what makes the formula resolve to one cell. Its value is a dot-path from the table below, so swapping it is how you pull a different value — one formula per column.

Seeing everything at once

Drop the "field" pair and the formula returns the whole response instead: two columns, field name on the left and value on the right, spilling from the cell you typed in.

=VERVE("cuidgenerator")

Good for exploring, not for filling down

The second row's table would land on top of the first's, and every cell after the first reads #REF! (#SPILL! in Excel). Keep one per sheet, or name a field, and leave the cells below and to the right empty.

Response fields

Paths are relative to data. Each one is exactly what the "field" pair accepts, so swapping it is how you pull a different value into a cell. On a plan without a Premium field the cell reads #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

Use as "field"	Type	Example cell value	Description
`cuids`	array	`["cmj95ed27000000145v116use","cmj95ed2700010014uuounuyc","cmj95ed27000200147pwbz35y"]`	Array of generated collision-resistant unique identifier strings
`count`	number	`10`	Total count of CUIDs generated in this request
`format`Premium	string	`c + timestamp + counter + fingerprint + random`	Description of CUID component composition and structure format
`collision_resistant`Premium	boolean	`true`	Indicates whether generated CUIDs provide collision resistance guarantee
`sortable`Premium	boolean	`true`	Indicates whether CUIDs are naturally sortable by timestamp component

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() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

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`	A preview formula was copied as-is. Swap the placeholder for a cell reference.
`#ERR No "x" in cuidgenerator`	An option name this source does not take. The message lists the ones it does.
`#ERR No data point "…"`	The `"field"` path is not in the response. Check it against the table above.
`#PREMIUM(field)`	The field exists but your plan does not include it.
`#ERR Out of credits`	The cycle'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 does not 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.

Use cases

Distributed Databases: Generate safe unique keys across distributed database systems and shards
Horizontal Scaling: Create identifiers that work reliably across horizontally scaled applications
Event Sourcing: Generate sortable event identifiers for event sourcing and CQRS patterns
Multi-tenant Systems: Create unique identifiers across multiple tenants and isolated environments
