Extracting letter from a column

Krish_Penubarthi

Hi,

 

I have a column from which I need to extract letter based on white spaces.

the output depends on the white spaces in the input column.

 

Eg: 

Input                                 Output

Green                                GR

Sky Blue                            SB

Deep Impact blue              DIB

 

How can this be achieved.

 

Thanks.

So you want the first character of each word?

 

There's an array of methods you could use to do this, but here is a RegEx and summerize tool solution...

But, How can I get first 2 characters when it is a Single word like Bob in your example.

Use this formula:

 

IF !CONTAINS(TRIM([Field1]),' ') THEN Left(TRIM([Field1]),2)
ELSE REGEX_Replace(TRIM([Field1]),'(\w{1}).*?\s?(\w{1}).*?\s(\w{1}).*','$1$2$3')
ENDIF

And like this if they have to be uppercase:

 

IF !CONTAINS(TRIM([Field1]),' ') THEN Uppercase(Left(TRIM([Field1]),2))
ELSE Uppercase(REGEX_Replace(TRIM([Field1]),'(\w{1}).*?\s?(\w{1}).*?\s(\w{1}).*','$1$2$3'))
ENDIF

 

If there are more than 3 words just add: (\w{1}).*?\s?  

 

IF !CONTAINS(TRIM([Field1]),' ') THEN Uppercase(Left(TRIM([Field1]),2))
ELSE Uppercase(REGEX_Replace(TRIM([Field1]),'<here>(\w{1}).*?\s?(\w{1}).*?\s(\w{1}).*','$1$2$3$4'))   (and the dollar-4 , dollar5 and so on sign)
ENDIF

 

one per extra word needed :)

Personally I would just try and understand the amount of spaces in the word and then create a seperate stream to deal with that...

 

So you can use a filter tool with the statement...

 

REGEX_CountMatches([Field1],"\s") = 0

 

To create two streams, one for words with spaces, one for words with no spaces, then on the stream with no spaces you can then just use a left([field],2) statement; and apply the same logic as before to the 2nd stream.

 

Example attached.
