What to include in a home inventory spreadsheet

What this guide explains

Understand which columns belong in a maintainable home inventory spreadsheet, how to document belongings room by room, and how to keep protected backup copies.

• Work one room at a time and use one row per item or sensible item group so the record stays maintainable.
• Record a clear item name, description, brand or model, serial number, purchase date, and purchase price when those details are available.
• Write the protected filenames or storage locations for receipts and photos instead of trying to embed every supporting file in the spreadsheet.
• Treat estimated replacement cost as a personal estimate only; it is not an appraisal, proof of value, coverage decision, or substitute for an insurer's requirements.
• Keep at least one protected backup away from the home, update the inventory after major purchases, and do not put passwords or access codes in the file.

Start with a record you can actually maintain

A useful home inventory is not the longest possible list. It is a record you can update after a purchase, move, or annual review. Start with one room, recent purchases, or the items that would be hardest to identify later. Use one row for a distinct higher-value item and one sensible grouped row for similar lower-value belongings. A clear item name, room, quantity, and short description are enough to begin; missing details can be added in later passes.

• Begin with one room, recent purchases, or higher-value items instead of waiting to document the whole home.
• Use separate rows when a serial number, receipt, model, or condition matters; group similar lower-value items when that keeps the record manageable.
• Add a household label and last-updated date so a downloaded copy can be identified without putting a full address in the file.

Record identifiers and supporting files

The most useful columns help another person identify what the item is and find supporting records. Record the brand or model, serial number, purchase source, purchase date, purchase price, condition, and a personal replacement-cost estimate when those details are available. Keep the actual receipt and photos in protected storage, then place only the relevant filename or folder note in the spreadsheet. Photograph an overview and any model or serial label that could distinguish the item later.

• Do not put account passwords, access codes, or unnecessary personal identifiers in the inventory.
• Use consistent receipt and photo filenames so the spreadsheet points to records another person can locate.
• Treat the replacement-cost field as a note for your own review, not as an appraisal or coverage decision.

Download, back up, and review the inventory

The tool keeps a recovery copy locally in the current browser, but browser data can still be cleared or lost. Download an XLSX or CSV as a separate backup, keep more than one protected copy, and store at least one away from the home or in secure storage. Update the last-reviewed date after checking the file, add major purchases soon after buying them, and periodically confirm that receipt and photo notes still point to files you can open. Ask your insurer which documentation and valuation method it requires for higher-value belongings.

• Keep a dated filename so older versions are not silently overwritten.
• Use CSV when you expect to import the record back into a simple data tool, and XLSX when you want a formatted workbook.
• Review the inventory after a move, major purchase, renovation, or change in coverage needs.
