Built around the collection
Less scrolling. More collecting.
BackIssue groups large libraries into meaningful collections and series, with the details collectors actually care about.
Owned and missing
Track every item’s status and quickly convert a wishlist or missing item into an owned collectible.
CLZ import
Bring an existing comic collection over using a compatible CSV export instead of starting from zero.
High-quality photos
Add a cover plus additional detail photos, then pinch and drag to inspect them on your phone.
Grading details
Keep raw items simple or record certification details for graded comics and trading cards.
Collection value
Record purchase prices, estimated worth, sales, and a collection-level value snapshot.

How to import your CLZ comics
You do not need to enter every comic again. Export your CLZ collection as a CSV or TXT file, then let BackIssue create the comics and collections for you.
1
Sync CLZ Comics to the cloud
Open the CLZ Comics app, open its menu, choose Sync with CLZ Cloud, and wait for the sync to finish. This makes sure your latest additions and edits are included.
2
Open CLZ Cloud on a computer
Visit cloud.clz.com and sign in with the same CLZ account. CLZ currently creates the export from its Cloud website rather than directly inside the mobile app.
3
Create your export file
Open the menu in CLZ Cloud and choose Export to CSV/TXT. Select the comics you want to move and include the fields listed below. Choose a comma-separated CSV when available, then press Generate and download the file.
Series or Series Name RequiredIssue NumberTitlePublisherRelease Date or YearVariantGrade or ConditionQuantityStorage Box, Folder, Collection, or LocationCollection Status
4
Move the file to your phone
Email the downloaded file to yourself, save it to Google Drive, or transfer it with a cable. On your Android phone, download it into Files or another folder you can find easily. Keep the file as .csv or .txt—do not convert it to a PDF.
5
Import it into BackIssue
Open BackIssue and tap the three-line menu. Choose Import CLZ file, find the CSV or TXT file, and select it. BackIssue will show how many comics it found before anything is added. Tap Import to finish.
6
Review your new library
Your CLZ folders or storage boxes become collections in BackIssue when that column is included. Rows marked as wishlist become missing items; the rest import as owned. BackIssue also skips matching duplicates during later imports.
CLZ and CLZ Cloud are third-party services. BackIssue is not affiliated with or endorsed by CLZ.
