Why this tool is useful
Use this diagnostic for logs, delimited files and pasted data where tabs, carriage returns or other non-printing controls cause alignment and parsing problems.

Control Character Visualizer
Render ASCII and C1 control characters as named tokens while preserving normal Unicode text and counting each control code.
Ready. Your working data stays in this browser.
How it works
The browser replaces recognized control code points with labels such as [TAB], [LF] and [ESC], then lists their hexadecimal values and totals.
Practical example
A tab between first and column becomes [TAB], making the invisible delimiter unambiguous without modifying the source textbox.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
