Fix Date Formats in Excel

Fix Dates

Turns text dates, number based dates and mixed styles into real Excel dates and applies the display format you choose. You can write the result to a new column, which is the safe option, or change the same cells. It recognizes dates written with dots, slashes, dashes or spaces, and plain date numbers such as 46590. An impossible date is left as it is so nothing is guessed wrong.

In short: Turns text dates, number based dates and mixed styles into real Excel dates and applies the display format you choose.

An impossible date is left as it is so nothing is guessed wrong. Real dates (same cells or a new column) + formats. Your source data stays unchanged and can be reversed in one step with Undo Last.

What it is for

Fix Dates is used to convert text/serial/mixed dates to real dates and format them.

When to use it

It earns its place whenever you have to standardize a date column entered in mixed formats.

Example scenarios

What it needs

A single column and an options dialog (target format, clear-only, new-column vs same-cells) + confirm. Supported data types: text, number, date (by selection).

How to use it

Select the range holding the dates.
Run Fix Dates from the Date group on the XLMind Data tab.
Pick the settings you need in the window that opens.
Confirm; real dates (same cells or a new column) + formats.

What it produces

Effect on your data and undo

How it differs from similar tools

It sweeps the entire selection at once, so no cell is missed the way manual passes miss them; Undo Last covers the whole change.
