Why this tool is useful
Audit and reorganize an address book in a spreadsheet while neutralizing formula-like contact fields and keeping every source record inside the browser.

Private VCF Contacts to CSV
Flatten contacts from a saved VCF file into spreadsheet-ready CSV with display name, structured name, UID, email, phone, organization, title, categories, URLs and notes.
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
Each complete vCard becomes one bounded CSV row; repeating properties are joined with explicit separators and formula prefixes receive a protective literal marker.
Practical example
Convert a CRM export, group rows by organization or email domain, and identify contacts without a UID or usable email address before a controlled import.
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.
