Why this tool is useful
Review, sort or archive a bookmark collection in a spreadsheet while retaining the original folder context and avoiding a cloud conversion upload.

Private Browser Bookmarks HTML to CSV
Convert a browser bookmark HTML export into CSV rows with title, URL, folder path, domain, scheme, saved date and tags, with spreadsheet-formula neutralization.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
How it works
The local parser flattens the validated folder tree into explicit columns, escapes CSV syntax and prefixes cells that spreadsheet software could otherwise interpret as formulas.
Practical example
Convert a Firefox export, sort the resulting CSV by domain or folder_path, and identify old collections without opening or checking any saved website.
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.
