-Excel-buider-vanilla is at the minimum 6x times smaller compared to the most used libraries (we can compare via `Bundlephobia`), excel-builder-vanilla is 22Kb gzip while [XLSX](https://bundlephobia.com/package/xlsx) is 136Kb and [ExcelJS](https://bundlephobia.com/package/exceljs) is 251Kb gzip.

 - excel-builder-vanilla only offers Excel export (writing) but without any reading capabilities
