    description: >-
      First-party Google Sheets add-on exposing Market Data as custom
      spreadsheet formulas (stock data, option chains, option data, option
      lookup, market status, earnings). Formulas authenticate with the account
      token and bill against the same API-credit model - since April 2026 a
      formula costs 1 credit on its first run per day and all subsequent
      recalcs are free. Includes Extensions-menu refresh actions (Refresh
      Current Sheet, Refresh Current Sheet Errors) and in-cell numeric error
      codes (e.g. [ERROR-402]).
