Spreadsheet Defined Names

Introduction

In spreadsheet applications, the defined names serves as a method to assign more readable labels to cell references or ranges, enhancing formula readability and maintainability. This concept, common in Excel, is also available in Jspreadsheet, allowing for an Excel-like experience within a JavaScript data grid.

Key Concepts

  • Defined Names: Labels representing references to constants, single cells, cell ranges or formulas.
  • Named Ranges: A specific defined name that refers to a cell range, facilitating easier reference in formulas.

Important Notes:

  • Enterprise feature: This feature is only available with the Premium Distribution with the Formulas Pro extension enabled.
  • Capital Case: All defined names should be defined with capital letters.
  • Scope: All defined names are going to be created on the spreadsheet level scope.
  • Name Conflicts: Do not use reserved names, such as names of cells, ranges or functions.

Documentation

Methods

You can use the following methods to read or create new defined names programmatically in your spreadsheet software.

Method Description
getDefinedNames Get a name by index.
@param {string} index - defined name identification.
spreadsheet.getDefinedNames(index: String) => Object
setDefinedNames Create or update one or multiple names.
@param {array} - Array with the indexes.
spreadsheet.setDefinedNames(names: Object[]) => void
resetDefinedNames Reset one or multiple names.
@param {array} - Array with the indexes.
spreadsheet.resetDefinedNames(names: Object[]) => void

Settings

All available properties to define a validation

Property Description
definedNames: array An array of defined names
