How to partially cut bytes in the middle of a string using Mapper

Question

The 13th to 18th bytes in a string is an ID, and I would like to use the ID in subsequent processing.
How can I cut a part of a string by specifying bytes in Mapper?

Answer

You can use the [Left String (bytes)] logic or the [After Specified Character] logic to cut off bytes in the middle of a string.

Sample data: xxxxxxxxxxxxxxxxIDDATAxx

1. Cut 12 bytes with [left string (byte)] in Mapper and assign it to a variable.
2. Prepare another Mapper and add the following.
    Specify the variable in [After Specified Character], and get the 13th and subsequent bytes.
    Cut off the first 6 bytes from the string with [Left String (bytes)].

Result data: IDDATA

For details of each logic, see the following pages.
