Ways to use it

Clean a column of text

Fill =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "is_palindrome") beside messy text and get the normalized, analyzed, or translated version back — data cleaning without leaving the grid.

Analyze at scale

Score or classify a whole column of responses, reviews, or messages in one fill instead of one-by-one.

Compose with other formulas

Nest Check Palindromes's output inside your existing SUM, IF, or CONCAT logic like any other cell value.

Use it in your sheet

The same function works in both apps — install once, sign in with your key, and type it into any cell.

Google SheetsAdd-on

Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.

=VERVE("palindromechecker", "A man a plan a canal Panama", "field", "is_palindrome")
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.

=VERVE.CALL("palindromechecker", "A man a plan a canal Panama", "field", "is_palindrome")
Optional inputs

Tune the result by adding name=value before the field argument — in any order. Leave one out and its default applies.

  • ignorecase

    Ignore case when checking (default: true)

    =VERVE("palindromechecker", "A man a plan a canal Panama", "ignorecase", "true")
  • ignorespaces

    Ignore spaces when checking (default: true)

    =VERVE("palindromechecker", "A man a plan a canal Panama", "ignorespaces", "true")
  • ignorepunctuation

    Ignore punctuation when checking (default: true)

    =VERVE("palindromechecker", "A man a plan a canal Panama", "ignorepunctuation", "true")
Fields you can pull

Add a field name as the last argument to land just that value in the cell.

  • Is palindrome
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "is_palindrome")
  • Cleaned text
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "cleaned_text")
  • Longest palindrome substringPremium
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "longest_palindrome_substring")
  • Reversed text
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "reversed_text")
  • Length
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "length")
  • Options
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "options")
  • Options › Ignore case
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "options.ignore_case")
  • Options › Ignore spaces
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "options.ignore_spaces")
  • Options › Ignore punctuation
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "options.ignore_punctuation")
  • Text
    =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "text")

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

Check Palindromes, answered

Everything you need to wire it into a sheet.

How do I pull Check Palindromes into Google Sheets?
Install the VerveSheets add-on, sign in once with your key, and type =VERVE("palindromechecker", "A man a plan a canal Panama", "field", "is_palindrome") 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 Check Palindromes?
Check Palindromes returns is_palindrome, cleaned_text, reversed_text, length and options, 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.
Can I narrow what Check Palindromes returns?
Yes — Check Palindromes takes "ignorecase", "ignorespaces" and "ignorepunctuation" as optional inputs. They go in as "name", value pairs after the required ones, in any order, so =VERVE("palindromechecker", "A man a plan a canal Panama", "ignorecase", "true") shapes the result without changing anything else.
Which Check Palindromes fields need a paid plan?
longest_palindrome_substring is 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 Check Palindromes at once?
Yes. Put your text 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 Check Palindromes 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 Check Palindromes 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.
