DiffPerChar

Easily compare two strings and visualize the differences on a per-character basis using this straightforward, single-file HTML tool.

URL Arguments

Customize input texts and column names through the URL parameters:

• textA=
• textB=
• columnA=
• columnB=

Example:

https://ththoma.github.io/DiffPerChar/?textA=hello&&textB=world&&columnA=A&&columnB=B

Why Use DiffPerChar?

During a project where I managed user values in text format and needed to identify differences, I found myself manually comparing strings without a character-by-character difference tool. Unable to find a similar solution, I decided to create one.
