Spreadsheet validations

Data validations in Jspreadsheet enable the creation of rules for the data entered in the grid, ensuring that users input valid or expected data types.

Upgrading from version 9
Starting from JSS version 10, the validations feature can be used without the validation extension. The extension is now limited to providing a no-code modal where users can create their own rules. Also, you can use column range such as Sheet1!E:E

Methods

Below are the methods available to set or retrieve validations for one or multiple cells in Jspreadsheet:
MethodDescription
getValidations Get validations by index.
@param {number} index - validation index.
getValidations(index: Number) => Object
setValidations Add or edit a new validation.
@param {object} - Array with the validations.
setValidations(validations: Validations[]) => void
resetValidations Add or edit a new validation.
@param {array} - Array with the validation indexes to be reset. Null to delete all validations.
resetValidations(validations?: Array) => void
loadValidations Get all validation rules applicable for one cell based on its coordinates.
@param {number} - x
@param {number} - y
loadValidations(x: Number, y: Number) => Object[]
hasErrors This method returns true if a cell fails to meet all the defined validation criteria. If invoked without arguments, this method will scan the entire worksheet and return true if it detects validation errors.
@param {number?|string?} - x | column name | undefined
@param {number?} - y | undefined
hasErrors(col?: Number, row?: Number) => Boolean


Events

Events related to validations.
MethodDescription

Validations[]

All available properties to define a validation
PropertyDescription
index: number Index of an array of validations.
