Turn your whole address book into a spec-correct XLSX, CSV, or vCard file — verified to open and re-import before it leaves the app.
Coming soon to theApp Store
Cardvault exports your iPhone address book into files that actually open. It produces spec-correct vCard 4.0, valid XLSX that opens in Excel, Numbers, and Google Sheets, and clean CSV with one row per contact and labelled columns for multiple numbers and emails.
Before you export, Cardvault runs a pre-flight check: it parses its own output back in and shows a verified badge with the contact and field counts. Corrupt spreadsheets, unescaped commas that silently eat data, vCards that a mail service rejects — the check catches the whole class of problems before the file ever leaves your phone.
Everything happens on-device. Your contacts are read locally, the file is generated locally, and nothing is uploaded anywhere. Cardvault never deletes phone contacts — there is no delete button in the app — and re-import is additive with a dedupe preview.
vCard 4.0, XLSX, and CSV — each written to spec, so the file opens in Excel, Numbers, Google Sheets, Google Contacts, and Outlook.
Cardvault re-imports its own output and shows a green verified badge with the exact contact and field counts before you share anything.
Export your whole address book, a group, or a hand-picked subset — whether that is 50 contacts or 5,000.
Choose which fields export, rename columns, and split multiple numbers into labelled columns, with a live preview of the first rows.
Save to Files, AirDrop, or any share-sheet destination. Email is one option, not the only fragile path.
Cardvault never deletes contacts from your phone, and re-import is additive with a dedupe preview.
Select all contacts, a group, or hand-pick a subset. The count updates as you choose — no cap at any size.
Pick vCard 4.0, XLSX, or CSV, then toggle fields and rename columns with a live preview of the first three rows.
Cardvault parses its own output back in and shows a verified badge with the contact and field counts.
Save to Files, AirDrop it, or send it anywhere from the share sheet — a clean, dated file ready to import.
The iPhone's built-in Contacts app can share vCards but has no spreadsheet export, so you need an app that reads your address book and writes a real XLSX file. Cardvault does exactly that on-device: pick your contacts, choose XLSX, map the columns you want, and save the file to Files or share it. The output is a valid spreadsheet that opens in Excel, Numbers, and Google Sheets.
Choose the CSV format in Cardvault, pick which fields to include, and export. The file follows the CSV standard with proper escaping, one row per contact, and labelled columns for multiple phone numbers and emails — so a contact with a mobile and a work number keeps both, in separate named columns, instead of collapsing into a mess.
A vCard (.vcf) is the standard file format for exchanging contact cards between phones, email services, and address book apps. One file can hold a single contact or an entire address book. Cardvault writes vCard 4.0 per the RFC 6350 specification, with correct escaping and line folding, so the file imports cleanly instead of dropping fields.
The usual culprits are formatting errors in the file: unescaped commas or semicolons, broken line folding, or duplicated character-encoding declarations. Many export tools produce these malformed files, and the importer either rejects them or silently drops data. Cardvault writes spec-correct vCards and then re-imports its own output as a verification pass before you export, so the file you send is one that parsers accept.
Yes. Cardvault lets you export everything, a specific contact group, or a hand-selected subset — tick the people you want and the count updates live. This is handy for sending a team list to a colleague or moving just your business contacts into a CRM.
Most CRMs import contacts from a CSV or spreadsheet with named columns. Export from Cardvault as CSV or XLSX, use field mapping to match the column names your CRM expects, and check the live preview of the first rows before you export. Because multi-value fields come out as labelled columns, the CRM import wizard can map them cleanly.
Not with Cardvault. Exporting only reads your address book and writes a file — your contacts stay exactly where they are. Cardvault is non-destructive by design: there is no delete-all function anywhere in the app, and re-importing is additive with a preview of duplicates before anything is written.
It depends entirely on where the app sends your data — some free contact tools are operated by data brokers. Cardvault processes everything on-device: contacts are read locally, files are generated locally, and no contact data is ever transmitted anywhere. The export file goes only where you send it.
Yes. Cardvault shows every available field — names, phones, emails, company, addresses, birthday, notes — as toggles, and you can rename the output columns too. A live preview of the first three rows updates as you change the mapping, so you see the final shape of the file before exporting.
Cardvault checks for you before the file leaves the app. It parses its own output back in — the same operation an importer would perform — and displays a verified badge with the number of contacts and fields that round-tripped intact. If the file could not be re-imported, you would know before sharing it, not after.
Cardvault keeps every number and labels it. In CSV and XLSX output, a contact's mobile, work, and home numbers each land in their own named column rather than being merged into one cell or silently dropped. A toggle in field mapping controls how multi-value fields split.
Cardvault has no contact cap. Whether your address book holds a hundred contacts or many thousands, the whole set exports in one file, and the verification badge confirms the full count made it through.
You decide at delivery time. Save to Files is the primary path — the file lands in the folder you choose with a dated name — and AirDrop, email, and every other share-sheet destination are available too. The file is a normal document you can open, move, or back up like any other.
Export your address book to Excel, CSV, or vCard — and know the file opens before you send it.
