How to Stop Excel From Changing Numbers to Dates

Excel stores dates as serial numbers, therefore when we enter a number like 4/20 into a cell, Excel changes the number to date as 20-Apr. Excel is programmed in this way, so we need to apply some fixes and learn how to stop Excel from changing numbers to dates.

How to Fix Auto Date

We face this problem while entering fractions data in cells. Like when we enter fractions like 1/4  or we insert numbers with a dash in between then Excel converts these numbers to date values automatically which is frustrating for data entry. There are multiple ways to stop Excel from auto formatting dates but we need to apply these fixes before entering numbers in cells.

By Adding Space or Apostrophe

Excel stops auto date functionality when we add space or an Apostrophe ( ‘ ) symbol before entering numbers in cells. An Apostrophe remains invisible in the cell when we press Enter key while entering number but space remains visible in the cell. This method is convenient when we need to enter a small amount of fraction data in cells.

By Formatting Cells as Text

While entering a large amount of data in cells having fractions and numbers separated by dash ( – ) symbol we need to learn how to stop Excel from changing numbers to dates. In this method, we format our targeted cells as Text and then enter numbers freely.

  • Highlight the targeted cells, right-click anywhere in these cells and select Format Cells.

By Adding Zero and Space

This method is ideal for entering only fraction data in cells. This method does not allow  Excel to change fraction numbers to dates. We need to insert a zero and space before entering fraction like 0 2/5, or 0 3/9. When we press Enter key, the zero disappears and the number becomes fraction number type and it does not allow Excel changing numbers to dates.
