Tool Guide
Introduction
The Online List Character Retention Tool quickly keeps characters at specified positions or position ranges in a list.
You can set a retention range or specific positions—for example, 6-8,12 means keeping the 6th–8th characters and the 12th character.
The character retention tool can also serve as an extraction tool, quickly batch-extracting characters at specified positions or ranges in a list.
