Collectors Den vs. spreadsheets for tracking a collection

Most collections start in a spreadsheet, and many stay there happily. A spreadsheet is free, flexible and works everywhere. So when is an app actually better — and when isn’t it?

Disclosure: this guide is written by the developer of Collectors Den. We’ve tried to be fair: where a spreadsheet is the better tool, we say so.

The short answer

• Choose a spreadsheet if you enjoy building your own system, want custom columns and formulas, need to work on Windows or Android, or want to share a read-only link with anyone.
• Choose a collection app like Collectors Den if you update your collection often on your phone, swap duplicates with friends, want several family members marking the same album, or want photos and progress without building anything.

Devices	Any — phone, tablet, computer, any OS	iPhone and Mac only
Updating on the phone	Possible, but fiddly with small cells	Built for tapping while you open packs
Missing / duplicate lists	Filters or formulas you maintain	Automatic
Comparing with a friend	Two lists side by side, by eye	Trade comparator shows both directions
Photos	Awkward	Photograph stickers, covers and consoles
Sharing	A link anyone can open	Per collection, by invitation, between Apple users
Custom fields and analysis	Unlimited	Fixed set of fields
Your data	In your spreadsheet account or file	On your device and your iCloud; Data Not Collected
Offline	Depends on the app	Yes

Where spreadsheets win

Flexibility. Any column, any formula, any chart. If you want to track the shop you bought each pack from or graph your pull rates, a spreadsheet does it and an app probably doesn’t.

Every platform. If you or your swap partners use Windows or Android, a spreadsheet goes everywhere. Collectors Den is iPhone and Mac only.

Public sharing. A spreadsheet link can be opened by anyone in a browser. Collectors Den shares only with people you invite, and they need the app.

Exports. Your data is already in a portable table.

Where an app wins

Speed in the moment. Marking twenty stickers in a spreadsheet on a phone means tapping tiny cells. In an app, the album is laid out for exactly that.

No maintenance. The missing count, the percentage, the duplicate counts and the per-section progress are always right because you never wrote the formulas.

Swaps. Comparing your duplicates against a friend’s missing list (and the reverse) is the most error-prone job in a spreadsheet. Collectors Den’s trade comparator does it from a code, pasted text or a file, and lets you reserve spares.

Photos and identification. Photograph the back of a sticker to check whether you have it, or a game’s cover to identify it. All of that is read on the device.

Family sharing. Several people marking the same album, each on their own iPhone, without overwriting each other’s cells.

You don’t have to choose forever

Collectors Den imports a CSV file, so a spreadsheet you’ve already built isn’t wasted. Columns it recognises include:

• number — the sticker or card number (codes like “POR 7” are fine)
• name — optional
• section or team — groups stickers into sections
• owned — values like yes, 1, x or true
• duplicates — how many spares you have

Save your sheet as CSV and import it to try the app with your real data.

A spreadsheet layout to start from

If you’re staying with a spreadsheet, this layout covers most collections:

number	name	section	owned	duplicates	notes
1	Badge	Intro	yes	0
2	Stadium	Intro		0
3	Goalkeeper	Team A	yes	2	reserved for Sam

Then add:

• A filter on owned to get your missing list.
• A filter on duplicates > 0 for your trade list.
• A cell with =COUNTIF(D:D,"yes")/(COUNTA(A:A)-1) for the completion percentage (the -1 skips the header row; format the cell as a percentage).

And it imports straight into Collectors Den if you change your mind later.

Verdict

If you love building systems, use several operating systems or want public links, keep your spreadsheet. If you want your collection to be quick to update, easy to swap from and shared with family on iPhone and Mac, an app saves you the upkeep — and Collectors Den is free to try, with no ads, no subscriptions and no account.
