Card-tracking apps decide your columns for you. A Google Sheets Digimon collection tracker doesn't — you build exactly the fields your collection needs, from purchase price to storage location, and you keep the file even if an app shuts down or changes its pricing model. Instead of manually re-checking values across three marketplaces every time you want to know what your binder is worth, build one spreadsheet that calculates total value and gain/loss the moment you update a single cell.

Why this matters

Digimon Card Game values move faster than most collectors expect, and the game's fanbase is smaller than Pokémon's, which means fewer tracking apps bother building Digimon-specific fields. Most third-party trackers lump Digimon into a generic "other TCG" category with no rarity codes, no color-strategy tags, and no way to separate sealed booster boxes from singles.

A spreadsheet you build yourself avoids all three problems. It also survives longer than most apps — Google Sheets isn't going anywhere in 2026, and the file exports cleanly to CSV whenever you want to move it. Delightful TCG sells the sealed product and singles most collectors are tracking, so the columns below are built around what actually shows up in a Digimon collection: booster boxes, singles by set, and grading candidates.

Before you start

• A Google account and about 15 minutes to build the template structure before entering a single card.
• A rough card count or set list. If your collection tops a few hundred cards, enter them in batches by set — dumping hundreds of rows into a blank sheet at once slows formula calculation down noticeably.
• The gotcha: never merge cells in the "Condition" or "Notes" columns. Merged cells silently break SORT, FILTER, and QUERY formulas later, and you will want those functions once the tracker passes 50 rows.

Set up your master sheet

1. Open a new blank spreadsheet in Google Sheets and right-click the tab at the bottom, then click Rename and call it "Digimon Master List."
2. In row 1, type header columns across: Card Name, Set, Rarity, Condition, Quantity, Purchase Price, Current Value, Total Value, Storage Location, Date Added.
3. Select the entire header row, then click View > Freeze > 1 row so headers stay visible while you scroll.

Expected result: a locked header row across 10 columns, ready for data entry.

Build your value formulas

1. Click the first Total Value cell (row 2) and type =E2*G2 to multiply Quantity by Current Value, then press Enter.
2. Click the cell again, grab the small square in the bottom-right corner (the fill handle), and drag it down to auto-copy the formula for future rows.
3. Add a Gain/Loss column and type =H2-(E2*F2) to show profit or loss against what you actually paid.

Expected result: Total Value and Gain/Loss recalculate automatically every time you update a Current Value cell — no manual math.

Color-code rarity tiers

1. Select the entire Rarity column.
2. Click Format > Conditional formatting.
3. Under Format cells if, choose Text is exactly, type "SEC" (Digimon's Secret Rare tier), assign a fill color, and click Done.
4. Repeat the rule for SR, R, U, and C tiers with distinct colors, referencing the breakdown in this guide to Digimon rarity tiers if you're unsure which abbreviation applies to a card.

Expected result: every row flags rarity by color without you reading a single cell.

Log sealed product on its own tab

1. Right-click the sheet tab area and click Insert sheet, then rename the new tab "Sealed Product."
2. Mirror the same header row from your Master List, but drop Condition and add a Box Count column instead.
3. Log sealed items — a Digimon World Convergence booster box, for example — as a single row using Box Count rather than treating it like a loose-card Quantity entry.

Expected result: sealed inventory and singles inventory live in separate views, and your Gain/Loss formulas never mix booster box math with per-card math.

Track pulls straight from a booster box opening

This is the second workflow this same sheet handles well: logging new cards the moment they come out of a pack instead of batching entry for later.

1. Open your Sealed Product tab, find the booster box row, and reduce Box Count by 1 once you crack it.
2. Switch to the Master List tab and add a new row for each notable pull, filling in Date Added with the actual date so your pull history stays chronological.
3. Leave Current Value blank until you've checked recent sold listings, then batch-update all new pulls from the same session in one sitting so every card reflects the same market snapshot.

Expected result: your opening history and your ongoing collection value stay in sync without a separate notebook or app.

Troubleshooting

• Total Value shows 0 for every row. The fill handle likely dragged over a merged cell. Unmerge the range, re-enter the formula in the top cell, and drag again.
• Conditional formatting color doesn't apply to new rows. The rule range was set to a fixed span like C2:C50 instead of the full column. Edit the rule and extend the range to C2:C1000 or further.
• Sorting scrambles your Total Value numbers. Formulas referencing relative rows break when you manually sort. Copy the formula column, then Paste special > Values only, before sorting — or use a SORT() formula in a separate output range instead of sorting in place.
• Rarity abbreviations don't match across cards. Digimon rarity codes vary slightly between English and Japanese print runs. Standardize on one scheme using Data > Data validation with a dropdown list so conditional formatting doesn't miss variants.
• The sheet slows down past a few hundred rows. Per-row formulas in every cell add up. Replace them with a single ARRAYFORMULA in row 2 that spans the entire column instead.

Customize your workflow

Once the base tracker works, expand it rather than leaving it as-is. Add a "Want List" tab for cards you're hunting, or a "Submitted for Grading" tab that moves a row out of Master List the moment a card ships to PSA or CGC. If your collection spans more than Digimon, the approach here applies directly to a collection that spans Pokémon, Digimon, and Hololive — same column structure, one extra tab per game.

FAQ

One last thing

The formula most collectors skip is the Gain/Loss column, and it's the one that actually tells you whether a set is worth continuing to buy. A Total Value column just shows what your collection is worth today; Gain/Loss shows whether your Digimon buying pattern in 2026 is making or losing money, card by card.
