To ignore all numbers stored as text, you need to open the Data tab and select the Text to Columns option. Then, select the Delimited option from the Convert Text to Columns wizard.

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.

Using the Excel Text to Column feature, you can choose how to split the column up, fix the width, or split at each comma, period, or other characters.

Excel's Convert Text to Columns Wizard works only on one column at a time. If the data is in the first column, for example, click on the letter "A" above the column to select the entire column.
