Move your collection from Dex
Move a Dex CSV from iPhone with its card IDs, variant rows and categories intact. Start by checking a few English cards you know well, then compare their quantities and finishes with the export.
Dex’s help says CSV export is on iOS and is a Dex+ feature.
Try your file before signing upCheck the first 200 rows without an account. No export yet? Paste a small list of your cards, or use the sample to see an example. The sample does not check your collection or unlock another app’s export.
1. Export from Dex
- In Dex on iPhone, go to Settings, then Data, then Export Collection.
- Save or share the exported CSV, keeping an untouched copy.
Exporting makes a copy; it does not remove cards from Dex. Keep the original file. Menu names can change, so use the official reference if your version differs.

Alternative to Dex: what carries over
House of Holos is a free Pokémon card collection tracker. From a Dex file, the importer reads your quantities, printings and folders where the file has them. It does not show market values, so those columns are not carried over.
- Card IDs and variant details used to find the matching catalog entry
- Quantities for supported English Pokémon cards
- Notes when the export includes them
- Category names, with the option to make binders in the signed-in importer

What to check in your Dex export
Our signed-in importer recognizes these fields when they are present in a supported layout. Missing information is not recreated from another app’s totals.
- Keep the original file encoding
- Our file reader handles Dex’s UTF-16 exports and semicolon-separated columns. Try the original CSV before reopening and resaving it in another app, which can change its encoding or separators.
- Check locale and variant separately
- A Dex ID helps identify the card, but the language and printing must still match your physical copy. Non-English rows are left unmatched rather than converted to English cards.
- Compare categories with binders
- A category is a grouping, not a Pokémon game or language. Review the proposed folder names and choose whether to create binders when saving; check quantities independently of those groups.
2. Preview before signing up
Start with a few known cards: a normal card, a reverse holo and a row with several copies. Compare rows and copies separately: one row with quantity four represents four cards. Review the set, number, language and printing before accepting a match.
The public preview matches the first 200 rows. For a larger file, that is partial coverage: the remaining rows still need full review. The complete file or list continues to the signed-in importer. A preview does not add cards to a collection. Our catalog is English Pokémon for now; other languages and games remain unmatched. A file opening successfully does not mean every row can be imported.
Matching runs in your browser with a limited catalog lookup of card-identification hints. That lookup excludes the CSV, filename, quantities, costs, notes, folders and cert numbers. The tool explains its file limits and temporary storage before you start.
Use a CSV export, not an Excel workbook, PDF, screenshot or JSON backup. For an unfamiliar layout, see the spreadsheet and column guide. You can also paste a card list into the public preview when you have no usable CSV.
3. Sign in, review and save
Keep this tab open when you continue. The preview holds your source and review choices temporarily in this tab, then starts a fresh full review for your signed-in account. If the draft is unavailable or you change browser or device, open the signed-in importer and reselect the original file or paste your list again. With browser storage blocked, keep that importer tab open too; reloading requires your source again. Nothing saves automatically.
Saving happens in the signed-in importer. Check its final preview against your source and your existing collection; cards you already have start unticked. Select the rows you intend to add and choose whether folders should become binders before confirming the import.
To replace existing counts from a newer export, deliberately choose Update cards I already have to this file’s counts and review the changes before applying them. Cards absent from that file stay as they are. Undo reverses eligible changes and tells you what it kept after later edits.
Read the full import guide for unresolved printings, count updates, folders and Undo. Purchase costs are your own records; House of Holos does not provide market prices.
