Excel functions

Reading and writing with Excel

The scripting function in the FVA-Workbench makes it possible to read data from or write values to an Excel file. For example, input values for a gear can be read directly from an Excel file in order to set the corresponding attributes in the gearbox model in the FVA-Workbench. The results of the calculation can then be written to the Excel file.

Formatting of the Excel file or cells can be done directly in the script using functions such as setBackgroundColor("B4", Red). Alternatively, a formatted Excel file can be imported as a template. The formatting of this file is used, and only the values in the specified cells will be added or replaced.

The functions for reading, writing, and editing Excel documents are all performed on a workbook object. The workbook is a data object that references a concrete Excel document.

The layout and contents of the specified Excel document are transferred.

let excelfile = "c:/example/excelfile.xlsx";
let workbook = workbookFactory.createWorkbook(excelfile);

The functions are then executed on the respective workbook object using dot notation.

workbook.setValue("A1", 5.241);

The following function is used to overwrite the Excel document with any changes made:

workbook.writeToFile(excelfile);

If the file specified in writeToFile() does not exist, it will be created.

Notice

A workbook object can also be created without specifying a concrete Excel document.

let workbook = workbookFactory.createNewWorkbook();

This procedure is recommended if no Excel template is used and the formatting is done exclusively using script functions.
