Cookie Inspector — format & attribute analysis

Detect cookie formats, find attribute issues and duplicates, and inspect TXT/CSV files. Reports contain metadata only — no cookie values, account IDs, passwords, or email addresses.

1. Input and format detection

Paste cookies or select a TXT/CSV/JSON file. Do not use live sessions for testing. The Inspector code processes the content locally in your browser.

Analysis mode

Source data

Ready. No input loaded.

Limits: up to 6 MB, 5,000 records, and 25,000 cookies. Passwords, emails, and IDs in other columns are neither parsed nor exported. Invalid delimiters are rejected.

2. Detection results

Counts of records, sets, and cookies. Successful structural parsing is not proof of an active session or account login.

The presence of cookie names such as c_user, xs, or fr may indicate a data format, but does not confirm login, session validity, ad status, or account restrictions.

3. Quality and attribute checks

Check domain, path, secure, httpOnly, SameSite, expiry, duplicates, and prefixes. Missing attributes in Cookie Strings cannot be reliably reconstructed and are not always errors.

Structural findings

Attribute overview

Cookie values and account IDs are not shown. Only issue codes and row numbers appear in diagnostics.

4. Download a sanitized report

JSON and CSV include aggregate stats, format labels, issue codes, and row numbers only. No raw cookies, values, passwords, IDs, or emails.

Review metadata before sharing even a sanitized report. To convert or repair formats, use Cookie Studio.

5. How-to and FAQ

Inspect a single cookie document

Leave Auto-detect selected, paste JSON, Netscape, Base64, Cookie String, or Set-Cookie data, and click Inspect cookies.
Review cookie counts and findings. Missing attributes are never invented.
Download a sanitized JSON report if needed; it does not contain cookie values.

Inspect TXT/CSV with multiple columns

Select Bulk TXT/CSV and upload a UTF-8 file.
Choose a delimiter (usually Automatic) and a cookie column, such as 3 for ID|PASSWORD|COOKIES|EMAIL|NAME.
Make sure errors are not caused by a wrong column. If the structure cannot be confirmed, the tool will not produce a falsely successful report.
Download a CSV with problem row numbers and error codes; passwords and cookies are never included.

Does this check whether a Facebook account is active?

No. This tool validates cookie syntax and attributes locally. It does not call Facebook or determine login validity or account status.

Will reports contain cookie values?

No. JSON/CSV reports only include counts, issue codes, and row numbers. The raw content remains in the input field until you clear it or close the page.

Can nobody else access input data?

The Inspector code itself makes no network requests or persistent-storage writes. However, other scripts loaded by the website platform could potentially access page fields. Full third-party-script isolation has not been independently verified.

Why are missing domain / secure attributes reported?

A Cookie String does not carry all browser cookie attributes. A missing attribute means the source did not specify it, not necessarily that a cookie is defective.

Can the tool restore damaged cookies?

No. Inspector identifies structural issues but cannot restore session values or automatically fix data. Use Cookie Studio for format conversion.
