(?:) is used for non-capturing groups.
?: says "find any of these on the list," but you don't need to remember which one you actually found later.

bihitakdass Let me know if that works for you

regexreplaceall(
  "\b\d+(\.\d+)?[kKmMbB]?\s*(?:[$€]|CHF|EUR|USD)\b",
  PUT YOUR STRING HERE,
  " "
)

"(?:[$€]|CHF|EUR|USD)" can you please share the purpose of ?: in this regex?

The pipe character in RegEx acts as an "OR" operator - so you can extend the RegEx pattern accordingly:

regexreplaceall("\d+[k|K|m|M|b|B]\s*(?:[$€]|CHF|EUR|USD)", ri!data ," ")

Hi Shubham,
Thanks this worked to certain extent but can you also suggest something for

1. Test 0.5M EUR Test :--> Test Test

2. Test 2121K€ test data :--> Test test data

3. Test 110EUR test data :--> Test test data

4. Test 7.95USD test data :--> Test test data

This k can be in caps also like 211K and not just K, it can be Billion("b" ,"B") ,Million( "m" , "M")

So can you help in modifying the regex to accept

There may be a more elegant way but it's easiest to understand and implement as two expressions:

an expression that takes as its input the data you want processed and performs a fn!reduce() on it, using the list of currencies you want to find and replace with the space character
a helper expression rule which is called by the above rule, which is called recursively by the fn!reduce() for each currency you want replaced. This uses the fn!regexreplaceall which uses a pattern to match on the string being and replaces all matches with, in this example, a space

The first rule looks something like this:

fn!reduce(
  rule!SJB_ER_replaceCurrencyValue,
  ri!data,
  { "\$", "€", "CHF", "EUR", "USD" }
  /* note that the dollar symbol in the list above includes the backslash escape character as */
  /* the dollar symbol has a speical menaing in regex expressions */
)

and the second rule looks like this:

fn!regexreplaceall(
  concat("[0-9]*k", ri!currency),
  ri!data,
  " "
)

If you need any further explanation as to what's happening here please ask.

Not sure about your exact requirements. You can try the following if the prefix and postfix string are fixed:

left("Test 1000k USD test data set", 5) & right("Test 1000k USD test data set", 13)

Let me know if that works for you.

regexreplaceall("\d+k\s*(?:[$€]|CHF|EUR|USD)", PUT YOUR STRING HERE ," ")
