What you get
When you finish cataloging a sale, LotJitsu hands you a single ZIP file. Everything Proxibid needs is inside it, named and arranged for the Proxibid importer.
The spreadsheet lists one lot per row, formatted for the Proxibid importer: lot number, title, description and the other fields Proxibid reads on import. Proxibid's importer includes a column mapping step, so you match the columns once when you upload. Open it in Excel or Numbers and it reads like a catalog you built by hand.
Your photos sit beside it, renamed to match their lots. You never have to line up IMG_4471.jpg with lot 12; the filename indicates which lot a photo belongs to and where it falls in that lot.
Nothing in the package is locked. It contains a spreadsheet and ordinary JPEG files, so you can review, adjust or reorder before uploading to Proxibid.
How the photos are named
Proxibid matches photos to lots by filename and names a lot's first photo apart from the rest, so LotJitsu names the first photo with the lot number alone, and every photo after it with the lot number, a hyphen, then a count that starts at 1.
1.jpg lot 1, photo 1 1-1.jpg lot 1, photo 2 1-2.jpg lot 1, photo 3 2.jpg lot 2, photo 1
The order you set in LotJitsu is the order Proxibid shows. Drag a photo to the front of a lot and it takes the bare lot number in the export; the rest renumber behind it.
Lot numbers come straight from your catalog, so if you renumber lots, export again rather than renaming files by hand. One mismatched name is enough to put a photo on the wrong lot.
How the upload works
- CatalogPhotograph and describe your lots in LotJitsu.
- CheckRun the health check and fix what it flags.
- ExportDownload the Proxibid package as one ZIP.
- UnzipOpen it to find the spreadsheet and photos.
- UploadImport the spreadsheet and the photos into Proxibid yourself, mapping the columns once.
LotJitsu never signs in to Proxibid. We do not ask for your Proxibid password, hold no connection to your account, and cannot publish, edit or close a sale. Step 5 is always yours.
Field limits
Proxibid caps lot titles at 100 characters, which is generous next to the other platforms. You have room to put the maker, the era and the material in the title where a buyer's search will find them. LotJitsu still checks every title against the limit before export, counting spaces and punctuation, and flags any that run over.
Room in a field is not a reason to fill it. Buyers scan. Keep the title to what a bidder scans for, the item and the one fact that sets it apart, and put the maker, model, condition and measurements in the description.
Photos per lot follow your LotJitsu plan. Proxibid does not publish a per-lot limit, so the plan is the number that matters.
Image sizing needs no attention. Proxibid resizes every photo to 1024 by 768 on its own side and accepts files up to 5 MB, and the photos LotJitsu exports are already under that, so there is no refit, crop or compression step between the ZIP and the upload.
What the health check catches
Before you download, LotJitsu reads the whole package the way the Proxibid importer will and flags anything that would cause trouble.
- Titles over 100 charactersListed by lot number so you can trim them.
- Lots without photosCaught before a bidder sees an empty listing.
- Lots that look like duplicatesFound by comparing photos across the sale.
- Values that are not what the field expectsA price or estimate that is not a number is caught before Proxibid rejects the row.
- Empty required columnsEvery row checked against the columns Proxibid reads.
Final steps to go live
Once the catalog is complete, you upload the package directly to Proxibid. Your Proxibid account is where your terms, your buyer's premium and your bidders live. You complete this final step to push your auction live.
“LotJitsu prepares the package. You decide when it goes live.”
Our goal at LotJitsu is to help you organize and save time in the cataloging process: naming, checking, formatting the columns for the Proxibid importer and packaging the ZIP. We do not sign in, upload, schedule or change anything on Proxibid. The step that takes a sale public always stays in your hands.
Q&A
Do I need to connect my Proxibid account?
No. LotJitsu never asks for Proxibid credentials. You download the package and upload it yourself.
Why is the first photo just the lot number?
That is the form Proxibid's importer expects: 1.jpg is lot 1's first photo, and 1-1.jpg, 1-2.jpg follow it. LotJitsu names them that way so nothing needs renaming.
Can I edit the spreadsheet first?
Yes. Keep the column headings and lot numbers as they are so the photos still match.
I renumbered some lots. What now?
Export again. Photo names follow lot numbers, and a fresh export renames everything in one pass.
How many photos can a lot have?
As many as your plan allows. Proxibid does not publish a per-lot limit.
Do I need to resize photos?
No. Proxibid resizes every photo to 1024 by 768 on its side, so the exported photos go straight in.
What if a title runs over 100 characters?
The health check lists it by lot number. Shorten it in LotJitsu and export again.
Can I sell the same catalog elsewhere?
Yes. Export a separate package for HiBid, LiveAuctioneers or AuctionNinja; each follows that platform's rules.
