Wedding planningHow to Combine Wedding Guest Lists from Both Families
Combine the lists into a shared column format, preserve a copy of each source, and review possible duplicates with someone who knows the families.
A little less to keep in your head
Clean a CSV or pasted guest list locally, map its columns and review possible duplicates without silently merging anyone.
Free · No account needed · Kept in this browser tab only · Downloads stay with you
Paste rows from a spreadsheet or choose a CSV. Your list stays on this device.
Include the column headings and at least one guest.
Start with a blank row, or select “Try an example” to explore fictional details.
Review results before downloading. XLSX contains editable values and a calculated snapshot, not live spreadsheet formulas. Use this tool again to recalculate. Blank files contain column headings.
A quick guide
Paste a table or choose a CSV, up to 2 MB and 1,000 rows.
Map source columns to the four fields.
Review flagged rows and remove only records you know are duplicates.
Whitespace is trimmed and repeated spaces collapsed. Possible duplicate name+household+function or shared contact+function combinations are flagged; all rows are retained.
No OCR, automatic country-code guessing, name transliteration or destructive merging. Shared family phones are not proof of duplicate people.
