XvbaCom

• Create Windows COM like Excel for use in Node Js

• It's a Framework where you extends your class and use the methods for conect to Windows COM

• You can pass multi params to methods (strings | numbers | booleans)

See ExcelXvba (Windows COM) created with this extension

• ExcelXvba

If you want to edit vba on VSCode see XVBA:

• www.xvba.dev

Importing

import { XvbaCOM } from "xvba-com";

//Just extends Your COM class 
export class Excel extends XvbaCOM {

    constructor() {
    super("Excel.Application");
  }

}

Example from ExcelXvba:

import { XvbaCOM } from "xvba-com";
import { Sheets } from "./Sheets";
import { WorkBooks } from "./WorkBooks";

export class Excel extends XvbaCOM {
  public WorkBooks: WorkBooks;
  private _Sheets: Sheets;

  public get Sheets(): Sheets {
    if (this._Sheets == undefined) {
      this._Sheets = this.CreateObject(Sheets);
      return this._Sheets;
    } else {
      return this._Sheets;
    }
  }

  constructor() {
    super("Excel.Application");
    this.WorkBooks = new WorkBooks();
  }

  Visible = () => this.SetBooleanValue("Visible", true);

  Name = () => this.GetStrValue("Name");

  Quit = () => this.CallMethodToGetVoid("Quit");
}
