How to delete special characters in strings in table?

Dear all,

I want to do the below:

  1. Read CSV file

  2. Check if special character exists ( ; or * ) in any cell

  3. If character exists (eg. between a word : smi;le) then delete this special character so the string becomes : smile)

  4. In the end I want to have the updated CSV file without the special characters in each cell ( if any)

I am not sure how to do this with “for each”…Please for your help

If you are using iteration just use
Replace(":","") or replace("*") @the.christopoulos

This was very helpful and it worked.

But, what If i want to replace the special character inside

the “for each row” loop without converting to string and converting back to csv again?

Can i replace special character while having the data as table?

@Palaniyappan @pattyricarte Could you help with this?

kindly elaborate pls

How can i delete the special characters in some string in the table but inside a “for each row” loop?

Without having to convert the whole table as a string and then convert it again ?

yah we can do that
but we need to know at what column the special characters might occurs then we can use a assign activity inside the for each row activity like this
row(“yourcolumnname”) = row(“rowcolumnname”).tostring.replace("*","")

–as we dont know the column name where the special character might occur and is dynamic so we are converting the dattable to a string as a whole and then it will be easy and faster to replace those special characters

–but still we can do within for each row loop with while loop (to iterate through all columns for each row) inside but it is bit slower when compared to the above method, thats why suggested that buddy

hope this would help you
