If your data includes inconsistent types, such as numbers mixed with text in the same column, this automatic step can cause ‘DataFormat.Error: We couldn’t convert to Number’.

Navigate to the "Number" group within the "Home" tab in Excel. Click the small arrow beside the "Number Format" box. Click "Text" to convert your cells to text formatting.

The purpose of the Convert Text to columns wizard is to separate the content of one excel cell into separate cells. You can set the delimiters that your data contain and set the column data format.
