Hi @stefanstick ,
If I understood it correctly, you have an array of strings, some of them containing special characters that must be replaced. To achieve it, you will need to first iterate your array by using the 'Apply to each' action, and inside its block, perform the replace operation.
Here is a quick example with an array of strings containing semicolons:
I'm also starting an empty array just to store the result after the replaces:
Then you add an 'Apply to each' just to iterate all values inside the original array:
Inside the 'Apply to each block', you will have a compose (where the replace is performed) and an 'Append to array variable', which will add the transformed string to the new array. For the replace task, we are using a very simple expression just to substitute the semicolons for dashes:
At the end of the flow, we have a 'Compose' just to display the final result of the clean array:
Alternatively, if you want to perform this replace task for each of the existing special characters in another array, you can use a similar logic:
In yellow, you have the special characters array, created before the 'Apply to each' loop. Inside the loop, you will need to create a compose to store the value of the current item mapped of the array of strings to be reviewed. Right after that, in pink, you insert a new 'Apply to each', where you will map the special characters array.
In blue, you are testing if the current iterated special character exists in the string to be reviewed, If yes, the replace process will be performed, but at this time, instead of just replace semicolons, it is replacing the item() value, which corresponds to the current special character.
This approach has a limitation: if the string in the array has more than 1 special character, it will be inserted as a duplicate in the 'clean array'. With some additional validations, you can prevent it to happen.
I'm also sharing some articles related to the actions used in this answer for further reference.
Let me know if it works for you or if you need any additional help!
