Why this tool is useful
Use HTTP Clear-Site-Data Builder when you need to validate and deduplicate supported storage directives for a Clear-Site-Data response header. The result is immediate and easy to verify before you reuse it.

HTTP Clear-Site-Data Builder
validate and deduplicate supported storage directives for a Clear-Site-Data response header.
Ready. Your working data stays in this browser.
How it works
Enter the values requested by HTTP Clear-Site-Data Builder. The browser validates the input, performs the calculation locally and produces a copyable result with clear errors.
Practical example
A practical use is to run HTTP Clear-Site-Data Builder on a small sample first, confirm the output, and then process the complete value or list.
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.
