Cannot convert to pdf from xlsx file over 1MB

Question

We are using the following api for converting file to pdf in Microsoft Graph API. https://graph.microsoft.com/v1.0/me/drive/items/[item-id]/content?format=pdf

I tried to convert a .xlsx file that was over 1MB to .pdf by this api. However, it returned following error:

{
  "error": {
    "code": "notSupported",
    "message": "...",
    "innererror": {
      "code": "OfficeConversion_NotSupported"
    }
  }
}

Is this behavior expected?

The reference for this api is below.

Answer 1

This is unfortunately a known limitation of PDF conversion for XLSX. I'd suggest making sure an idea exists, and is upvoted, on https://onedrive.uservoice.com/forums/913708/.
