xlsx_validation: Import data validation rules of cells in xlsx (Excel) files

Description

xlsx_validation() returns the data validation rules applied to cells in xlsx (Excel) files. Data validation rules control what constants can be entered into a cell, e.g. any whole number between 0 and 9, or one of several values from another part of the spreadsheet.

Usage

xlsx_validation(path, sheets = NA)

Arguments

sheets

Sheets to read. Either a character vector (the names of the sheets), an integer vector (the positions of the sheets), or NA (default, all sheets).
