Remove all special characters from the start and end of a string

Hi There,

 

I have been trying to use formulae to remove currency symbols from a string.

 

Here is what I am trying to achieve

 

 Data InputDesired Output
27,000.51 CAD27000.51
£28,000.5128000.51
HK$29,000.5129000.51
€30,000.5130000.51

 

I am aware that I can use the Data Cleansing tool to remove the letters and blank space.

 

What I need is a formula/expression which removes:

1) The special characters from the start of the string.  I would want the formula to say 'remove any special character, whatever it is/whatever they are, from the start of the string, to the left of the first number and to the right of the last number'

2) Removes the comma separators

 

What I have so far is this, but it requires me to define particular characters to remove:

 

Tonumber(replacechar(trim(regex_replace([Amount],"^-0{1,}",'-'),"0"),"£,$",""),1)

 

Can you point me in the right direction?

 

Thanks!

 

Rachel

Hey @RachRoberts 

 

You can try: REGEX_Replace([ Data Input], "[^\d.]", "")

 

Which basically says, replace anything that isn't (^) a number or a fullstop.

Would that work if I want  the following:

 

Have :///8.35.43

😕 8.5.44

:\\\8.4.45

\8.5.45

 

Would like the end result to be

8.35.43

8.5.44

8.4.45

and so on
