CardmendHow duplicates are found
Phone numbers are compared after normalising them, so 052-555-0101 and +972 52 555 0101 match. E-mails are compared without case, and Gmail dots are ignored. Names are compared across spelling variants, initials, Hebrew niqqud and Arabic letter forms.
Three levels, your decision
Groups are labelled “same person”, “probably the same” or “check carefully”. Only the first two are pre-selected. A shared office number with different names is shown but not selected.
Nothing is lost when merging
The merged contact keeps every distinct number, e-mail, address and note, the best photo and the name you choose. You can undo the last merge.
How it works
- Export your contacts as a vCard (.vcf) or CSV file from your phone, Google Contacts, iCloud or Outlook.
- Open the file in Cardmend. It is read on your device and is not uploaded.
- Fix phone numbers, review and merge duplicates, then download vCard, CSV or Excel.
What you get
Stays on your device
There is no server behind the converter, and the page's security policy blocks every network connection. You can turn off Wi-Fi after it opens.
Reads messy vCards
vCard 2.1, 3.0 and 4.0, quoted-printable text, folded lines, old character sets, photos, several phones and e-mails per person, iPhone custom labels.
Duplicates you can review
Groups are found by phone, e-mail and similar names. You see each group and choose which ones to merge and which name to keep.
Phone numbers in E.164
Numbers are checked with Google's phone number metadata and can be exported as +972521234567, in international or in national format.
Google, Outlook and Excel
Exports Google Contacts CSV, Outlook CSV, a clean CSV with one column per number, and Excel. Imports the same, plus any CSV with column matching.
Hebrew, Arabic and accents
Right-to-left names, niqqud and tashkeel, windows-1255/1256 files and UTF-8 come out readable, not as question marks.
Good to know
- Cardmend works with files. It does not sign in to Google, iCloud or Outlook: you export and import the file there yourself.
- Duplicate groups are suggestions. Similar names can belong to different people, so check each group before merging, and keep your original export.
- Photos are kept in vCard exports. CSV and Excel only mark whether a contact has a photo. Old .xls files and iCloud contact groups are not supported.
Questions
Will it merge two people who share a number?
Not by itself. If the names are different, the group is marked “check carefully” and is not selected for merging.
Does it change my phone's contacts?
No. Cardmend only changes the file you opened. You import the cleaned file yourself.
Are my contacts uploaded?
No. Cardmend runs in your browser. The converter page is not allowed to send data anywhere, and it keeps working offline.
What does it cost?
Opening files, checking duplicates and fixing numbers is free for all your contacts, and you can export up to 50 contacts. A lifetime key costs $9, paid once.
Which files can I open?
vCard (.vcf) from iPhone, iCloud, Android, Google, Outlook and older phones; Google and Outlook CSV; and any CSV or Excel .xlsx file, where you match the columns.
