What's in your export package

An export package is one ZIP file. It holds a spreadsheet (a CSV file) with one row per lot and every photo of every lot, named and laid out for the platform your catalog is set to. The package is built the same way whether you export on your phone or your computer.

The ZIP file

The ZIP is named after the catalog and the day it was built. A catalog named "Spring Estate, March 14" exported on 15 September 2026 downloads as spring-estate-march-14-2026-09-15.zip.

• The catalog name is written in lowercase letters and digits. Spaces, punctuation and accented letters become hyphens.
• The date is the build date in Coordinated Universal Time (UTC), not your local time. Late in the evening it can be a day ahead of the date History shows.
• If the catalog name has no letters or digits at all, the file is named auction- followed by the date.

Inside the ZIP

Everything sits at the top level. There are no folders.

1. The spreadsheet comes first. It has the same name as the ZIP, ending in .csv.
2. Then the photos, as JPEG files. Lots follow in lot number order, lowest first, and each lot's photos follow in the order you set on the lot, Cover Photo first.

A catalog of 40 lots with 3 photos each gives a ZIP of 121 files: 1 spreadsheet and 120 photos.

The spreadsheet

• One header row, then one row per lot, in lot number order.
• The columns are your platform's, in your platform's order, under your platform's header names. A field your catalog does not use still has its column, left empty. Each platform's columns are listed in Platform reference.
• The lot number column is always filled from the lot's own number.
• Every other value is written exactly as it is on the lot. A value over the platform's character limit is written in full; the export warned you about it but did not change it.
• When the catalog uses Use Rich-text (HTML) formatting, descriptions carry simple HTML formatting tags. Otherwise they are plain text.
• On the free White Belt plan, every description ends with a LotJitsu line: "Catalog created using the LotJitsu App" on a General Purpose catalog, or "Auction catalog created using the LotJitsu App" on a catalog set to an auction platform. On a paid plan the line is added only if the account owner turned it on in Settings. If your platform takes HTML, the line is its own paragraph; otherwise it follows the description after a blank line. The line is added only to the package, never to your lots.
• The file is UTF-8 with Windows line endings, so accented letters come through correctly in platform import tools.
• A value that starts with =, +, - or @ gets an apostrophe in front. This protects you if the file is opened in a spreadsheet program, which would otherwise treat the value as a formula. If any of your values start this way, check the listing preview on your platform after you upload.

The photos

• Each photo is named with its lot number and its position on the lot, for example 12-1.jpg for lot 12's Cover Photo. The exact pattern differs by platform (LiveAuctioneers uses an underscore, Proxibid names the first photo 12.jpg). See Platform reference.
• Photos are the copies LotJitsu stored when you added them: cropped to 4:3, the right way up, and saved as JPEG. Rotating a photo or choosing a new Cover Photo changes what goes into your next package.
• A photo is resized for the package only when your platform needs it smaller. The photo on your lot never changes.

What is left out

• Lots you deleted.
• Lots you took out of the export when you resolved Possible Duplicate Lots. They stay out of every later package until you put them back.

Good to know

• Do not rename, move or edit the files before you upload them. Your platform matches photos to lots by file name, and a spreadsheet saved again by Excel or Numbers can change in ways your platform refuses. To change a lot, edit it in LotJitsu and export again.
• In rare cases a photo cannot be read while the package is built. LotJitsu leaves that photo out, numbers the lot's other photos with no gap, and Export Complete tells you, for example "1 photo couldn't be included in this package." For Proxibid, the next readable photo becomes the cover. Check the lot's photos in LotJitsu and export again if you need them all.
• Packages are kept for one year, then the file is removed. Download and keep your own copy if you need it longer. See Find and download a previous export on your computer.
• Next step: Upload your package to your auction platform.
