Reader Doug H. wins an autographed copy of Excel for Auditors from CFO and MrExcel for his question: "Is there a way to build a function that addresses reformatting strings of numbers or text? For example, our I-Series software lists dates as an 8-character value/string in the following format, YYYYMMDD. I have to write a long formula as follows:
Doug continues: "Is there an easier way [to solve this problem], or can I create a function that mirrors my formula instead of re-creating it every time I download information? This could be a huge time saver for me."
Here's a simple approach to dealing with Doug's date-conversion problem.
Solving with Doug's Formula
Doug is getting data that looks like the column shown in Figure 1. (See all three stages of Doug's original data below.)
I love Doug's formidable formula, yet it must be a pain to type. Furthermore, as you see in Figure 2, it provides the right answer in the wrong format. In order to get the right format, you have to choose a Date format from the dropdown on the Home tab of the ribbon as shown in Figure 3.
The Amazing Solution
I was amazed that the following solution actually works. Follow these steps:
1. Select the range of cells containing dates in the YYYYMMDD format.
2. Choose Data, Text to Columns.
3. In Step 1 of the wizard, choose either Delimited or Fixed Width.
4. Click Next twice.
5. In Step 3 of the wizard, open the Date dropdown and choose YMD format as shown in Figure 4 (below).
6. Click Finish.
The numbers will change to real Excel dates. If the column is not wide enough, as shown in Figures 5 and 6 (below), double-click between the column headings to widen the column. Miraculously, the column of 20101223 values is now replaced with real dates.
