What is quickbase-formulas?

A guide to Quickbase formulas, the expressions used to calculate or display values in Quickbase fields. It covers text, numbers, dates, checkboxes, rich text, and action buttons.

Use it to write, review, correct, and test Quickbase formula fields and formula-based buttons.

Quickbase formulas use strict types and specific syntax, so spreadsheet-style guesses often fail to compile.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00098	$0.01014
Opus 5.5	$0.00039	$0.00406
Sonnet 5.5	$0.00020	$0.00203
Haiku 4.5	$0.00010	$0.00101

Security

Grade A, and why

quickbase-formulas scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quickbase formulas

Quickbase's formula language is strongly typed and not spreadsheet-like. Most "obvious" guesses are wrong. Before writing or approving a formula, ground it in the authoritative, source-cited reference in this repo's formulas/ folder — and always the load-bearing rules below.

The reference (open the file that fits the task)

formulas/formula-language.md — syntax, types, operators, nulls, If()/Case(), date/duration arithmetic, field result types, compile errors, and testing via POST /v1/formula/run.
formulas/functions.md — the complete function catalog with signatures. If a function isn't in this file, assume it doesn't exist.
formulas/rich-text-and-buttons.md — the allowed HTML subset for Formula – Rich Text fields, and Formula – URL action buttons.

Load-bearing rules (the ones people get wrong)

Equality is a single = (never ==); not-equal is <>. Concatenate text with &. and / or / not are lowercase keywords.
Strongly typed, no silent coercion. Convert explicitly: ToText, ToNumber, ToDate, ToFormattedText, ToDays, ToUser. A checkbox is Boolean — use If([Box], …), not [Box] = true; to do math on it, ToNumber([Box]).
Dates have no literal form. Build them: Today() (Date), Now() (Date/Time), ToDate("Jan 30, 2026"), Date(y,m,d). Add time with a Duration: [Start] + Days(7), never [Start] + 7. Months/years: AdjustMonth/AdjustYear.
Subtracting two dates yields a Duration, not a number. For a day count use ToDays([End] - [Start]) and put it in a Formula – Numeric field.
If(c1,r1,c2,r2,…,default) returns the first true branch, and every branch (incl. default) must be the SAME type. Same for Case().
The field's result type is part of the contract. HTML renders only in a Formula – Rich Text field (a Text field shows the tags literally). A Numeric field's formula must return a Number, etc.
var variables: var number Total = [Price] * [Qty]; then reference with $Total. Each declaration ends in ;. Names are letters only. Use // line comments (block /* */ is not supported).
There is no Power, Avg, Distance, or "ends-with" — use ^, Average, manual haversine, and there is no ends-with. Check functions.md's name-corrections table before using a function you're unsure of.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
