title: Import data to an excel online
body: <p>What would be the best option to programmatically import large dataset (10 MB) file into an excel online workbook and protect the cells.</p>
  <p>Dataset file CSV / Parquet format is stored in azure data lake storage.</p>
  <p>I reviewed the Microsoft Graph API however I could not find a way to protect the range of cells. Only worksheet can be protected. Also could not find any API to import data.</p>
  <p>Any feedback would be much appreciated.</p>
