Overview

Title Capitalization trims `text` and replaces tabs and line breaks with spaces before converting, so multi-line input comes back on one line. `style` is lowercased and must be one of the documented values; anything else is rejected with a 400 error.

The headline styles `title-case`, `ap`, `apa`, `chicago`, `mla`, `nyt`, `ama`, `bb`, `wikipedia` and `email` all call the same function from the title-case library. It capitalizes the first letter of each word but leaves a fixed list of lowercase small words alone in mid-title, including a, an, and, as, at, but, by, for, if, in, nor, of, on, or, so, than, that, the, to, up, via, vs, with and yet. The first and last words, and a word after a colon, quotation mark or sentence-ending punctuation, are always capitalized. Small words are matched case-sensitively, so a capitalized "The" in mid-title stays capitalized. Words that already contain a capital after the first letter, as well as URLs and email addresses, are left as typed. The library does not lowercase existing capitals, so an all-caps input stays all caps; send lowercase text if you want a clean conversion.

`sentence-case` uses the change-case library, which splits the text into words (including at camelCase boundaries), lowercases them, capitalizes the first and joins them with spaces; punctuation between words is dropped in the process. `uppercase` and `lowercase` are plain conversions. `first-letter` uppercases the first character and lowercases the rest. `alt-case` alternates lower and upper case by character position, counting spaces and punctuation, and `toggle-case` swaps the case of every character.

`style` echoes the normalized style name and `text` holds the result. The response is identical on every plan.

Formula

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

=VERVE("titlecapitalization", A2, B2, "text")

A2 holds text, B2 holds style. Arguments go in that order — the same order as the table below.

With literal values

Nothing has to come from a cell — typed values work the same way.

=VERVE("titlecapitalization", "hello world", "title-case", "text")

Inputs

Required inputs are positional, in the order below, followed by the field. Everything else is passed as a "name", value pair after that — the same shape as SUMIFS. Premium inputs are accepted on every plan but only take effect on plans that include them.

What lands in your sheet

The field — the argument after the inputs — 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

Leave the field out 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("titlecapitalization", A2, B2)
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 argument 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 the fieldTypeExample cell valueDescription
stylestringtitle-caseThe selected case style applied to the text
textstringComprehensive Analysis of Quarterly Financial Performance and Strategic Initiatives for Sustainable…The converted text in the requested case style

Filling a whole column

Both platforms make one batched call for a column rather than one request per cell, and both cost the same — 1 credit per row looked up. How you write it differs, because the two runtimes batch at different points.

Rows 2–100 in one call
=VERVE("titlecapitalization", A2:A100, B2:B100, "text")

In Google Sheets, give the arguments ranges and the answers spill down from the cell you typed in. Custom functions there run synchronously and in isolation, so dragged cells cannot be coalesced — the range form is how a column becomes one call. The field is required here: a per-row two-column table has nowhere to spill. Use a full column per input (A2:A100, not A2) — a single-cell reference is read as row 1 only and the rest of the column comes back blank.

In Excel, type the formula once and fill down — no range form and none needed, because its runtime is asynchronous and the add-in coalesces the calls a fill produces into a single batched request. Do not hand VERVE.CALL a range: Excel flattens it into positional arguments, so A2:A100 arrives as a hundred separate arguments and the cell reads #ERR rather than filling.

Either way, column A holds your text values and the answers land beside them, one row each, blank rows 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() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

Cell readsWhat happened
#ERR Not connectedNo API key saved. Open the side panel and connect your account.
#ERR Replace <name> with a cell or valueA preview formula was copied as-is. Swap the placeholder for a cell reference.
#ERR No "x" in titlecapitalizationAn 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 creditsThe 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.

  1. Install the add-in for Google Sheets or Excel.
  2. Open the side panel and sign in, or paste a key from your dashboard.
  3. Type the formula above into any cell.
