Excel: Arguments to the SUBSTITUTE Function Are Case Sensitive

The information in this article applies to:

Microsoft Excel for Windows, versions 2.x, 3.0, 4.0, 4.0a, 5.0
Microsoft Excel for OS/2, versions 2.2 and 3.0
Microsoft Excel for the Macintosh, version 2.x, 3.0, 4.0

SUMMARY

When using the SUBSTITUTE function in a Microsoft Excel macro or on a worksheet, one of the required parameters, old_text, is case sensitive.

MORE INFORMATION

The structure of the SUBSTITUTE function, which substitutes new_text for old_text in a text string, is:

   =SUBSTITUTE(text,old_text,new_text,instance_num)

If text is capitalized, but old_text is not, no substitution will occur and no error will be reported.

Steps to Reproduce Problem

Type the following formula on a worksheet:
```
      A1:=SUBSTITUTE("Sales Data","sales","Cost")
```
"Sales Data" is returned. No substitution has occurred and no error is reported. The same behavior occurs in a macro.

Change the formula as follows:

      A1:=SUBSTITUTE("Sales Data","Sales","Cost")

The formula will now correctly substitute "Sales" with "Cost" and return "Cost Data".
