Is there a way to look up patterns inside an MS Word document instead of an exact match?

I have a document where all decimals have been written as / instead of .. For example, 1.02 has been written as 1/02, because Persian typography uses / instead of . for the decimal point.

As / is not only used for decimals, and it has other applications, for example, fractions, percentage, etc., is there a way to find a pattern like N/M within a word document, where N denotes a decimal and M also shows another decimal number?

    A starting point may be Regular Expression for Find and Replace in Microsoft Word. Nov 30, 2014 at 12:19
  • Well it would be hard to move it to notepad if there were other text in the middle, lets assume that one is writing a journal article(please use latex instead) so they cant move it out of word, or something of that nature, they would loose all the other formatting. Dec 2, 2014 at 8:08

    I've just verified: the latest MS Word versions store Word documents (*.docx) as zipped XML based documents. Once you know how this structure works, you might unzip your *.docx file and do a pattern match in the resulting XML files structures.

like 'N/M' within a word document, where N denotes a decimal and M also shows another decimal number

Just for a search you can use ^#/^# as your search parameter. Under the more options, and find Special, there are some other options that can be helpfull.

Nb: ^# , is one decimal place so if you are looking specifically for x/yy then it would be ^#/^#^# etc.

to Replace,

This is a better option , perform search with ([0-9])/([0-9]) and replace with \1.\2 , and enable "use wildcards"

  • Thanks. this finds the hits. but Word does not accept ^#.^# for the replacement part. I want to leave the digits surrounding '/' intact and replace '/' with '.'. Nov 30, 2014 at 8:08

    try doing a search with this, "([0-9])/([0-9])" and replace with "\1.\2" , take out the double quote. and enable "use wildcards" Nov 30, 2014 at 8:19


Use Microsoft's implementation of regular expressions

Press CTRL+H » click on More » Enable Use wildcards

  • Find what: ([0-9]{1,2})/([0-9]{2})
  • Replace with: \1.\2

enter image description here enter image description here

This looks like a crazy search pattern so let's examine it:

  • [0-9] stands for a single numeric value (0,1,2,3,4,5,6,7,8 and 9)

  • {1,2} is used for counting occurrences of the previous character or expression. In our case this means: Search only for one or two numerics.

    Caution: If you're using a german Word, you have to use ; as separator instead of ,

  • / has no special meaning. It literally searches a slash

  • () the round brackets are important. They divide the pattern into logical sequences so we can later use \1,\2...\n in our replace pattern. This way we preserve values

VBA (better solution)

I suggest you to use a VBA method which adheres more to the default from other RegEx engines. They are better documented and more people can help you.

This macro asks for a RegEx pattern to search in the whole document and replace it with your given string.

Press ALT+F11 to open the VBA editor. Paste the code anywhere and execute it with F5

Sub RegexReplace()
    Dim RegEx As Object
    Set RegEx = CreateObject("VBScript.RegExp")    
    On Error Resume Next

    RegEx.Global = True
    RegEx.Pattern = InputBox("Find what:")
    ActiveDocument.Range = _ 
        RegEx.Replace(ActiveDocument.Range, InputBox("Replace with:"))        
End Sub
  • Find what: (?!\d)/(?=\d)
  • Replace with: .
