Spreadsheets are underrated for this job. Anyone telling you that you absolutely need software for a household inventory is selling something. So here is the honest boundary.
Where a spreadsheet wins
- You already know how to use it. No learning curve, no install, no vendor.
- It is portable forever. A CSV file will open in forty years.
- It is free, and it syncs anywhere you like.
- Sorting and totalling are trivial if you set up the columns properly.
For a household documenting twenty or thirty high-value items with receipts filed separately, a spreadsheet is a completely reasonable answer, and it beats the far more common alternative of doing nothing.
Where it starts to hurt
Photos. This is the real dividing line. A home inventory without photographs is much weaker evidence — see proof of ownership — and spreadsheets handle images badly. Embedded images bloat the file and distort rows; linked images break the moment the folder moves or the file is opened on another machine.
Attachments. Receipts, appraisals and warranty PDFs live in a parallel folder structure that has to be maintained by hand, and the link between row 47 and a file called IMG_2831.jpg exists only in your memory.
Reports. An adjuster wants a readable document grouped by room with photos inline. Getting that out of a spreadsheet means manual formatting every time you update anything.
Consistency. Free-text cells drift: "Living Room", "living room", "LR". Six months later the totals per room are wrong and nobody notices.
Backups. A spreadsheet with a folder of photos is two things to back up and one thing people actually back up.
Side by side
| Spreadsheet | Dedicated software | |
|---|---|---|
| Cost | Free | One-time or subscription |
| Photos per item | Awkward, breaks on move | Built in |
| Receipts and appraisals | Separate folder | Attached to the item |
| Totals by room and category | Manual formulas | Automatic |
| Insurer-ready PDF | Manual formatting | One click |
| Data portability | Perfect | Depends on export quality |
| Learning curve | None | An hour |
| Longevity | Decades | Depends on the vendor |
The question that actually decides it
Not "which is better" but how many items with photos are you going to record? Under about thirty, a spreadsheet plus a well-named photo folder is fine. Over a hundred — which is a normal household once the garage and closets are counted — the manual linking between rows and images becomes the reason the project stalls.
If you go the spreadsheet route
Set these columns from the start and never improvise: Room, Item, Make/Model, Serial, Purchase date, Purchase price, Replacement cost, Photo file name, Receipt file name, Notes. Use a dropdown for Room. Keep the photos in one folder with file names that begin with the row number. Back the whole folder up somewhere outside the house.
If you go the software route
The things worth checking before you commit are covered in best home inventory software: whether it works offline, whether the data file is yours, whether the export is genuinely usable, and what happens to your inventory if the company stops trading. Those four questions matter more than any feature list.
Full disclosure
We make HomeInvent, a Windows program for exactly this. That obviously colours our view, so the honest summary is: if a spreadsheet gets you to a finished, photographed, backed-up inventory, use the spreadsheet. The failure mode we are actually trying to fix is the household with no inventory at all.
