Legacy link resolver

What each line can be

Wrapped address

An address on the platform domain carrying a product number and a source mark. These rebuild into a source address when the source mark is one this ledger has observed.

Source address

A Taobao, Weidian or 1688 address. Nothing needs rebuilding; it is already the form a platform that is accepting orders will read.

Shortened form

A short link on the platform domain. It is recognised as such, but no source address is produced: this ledger has no verified expansion for shortened forms.

Another platform

An address from a different platform. It is identified by domain so you know what you are holding, and left for that platform’s own converter.

Not recognised

Anything else. Reported as unrecognised rather than guessed at.

How to read the result

The source address column is what you act on. If it is filled, that address is the listing your sheet was pointing at, in the form a platform reads directly. Paste it once into the platform you are using and confirm the listing opens before you build a plan around it.

The recorded column answers a narrower question: did this product number appear in the period this site last measured, and what did the source address do when it was requested? A number that is not in the sample is not a problem with your link. The sample is a selection, not a register, and most product numbers will not be in it.

Where a wrapped address carries a source mark this ledger has not observed, the line is reported as read but not rebuilt. That is deliberate. Producing a source address for an unobserved mark would mean guessing which marketplace it belongs to, and a wrong guess sends you to a dead page with confidence.

When the result is not usable

• Shortened forms. Recognised, not expanded. Open one in a browser to see where it lands, then run the destination through this tool.
• Unobserved source marks. Read, not rebuilt. The product number is still shown, and pasting the original address into a platform’s own search box is the remaining option.
• Addresses with no product number. Reported as unrecognised; there is nothing to look up.
• More than 200 lines. The first 200 are read and the rest are left for a second pass, rather than silently dropped.

Where the readings come from

Reading is a fixed rule set, not a lookup service. Wrapped addresses are recognised by their shape, the product number and source mark are read from the address itself, and the source address is produced from a mapping this site has verified against observed samples. The only source mark in that mapping today is WD, which maps to Weidian: it is the only value present in the 31 wrapped addresses this site has collected from publicly visible sheet pages.

The recorded column reads from period 2026-W39, published 2026-09-29, which holds 93 records. How each status is reached, including what an unrecorded result does and does not mean, is set out on the method page.

Common questions about this tool

Does it check whether the listing is in stock?

No, and neither does the recorded column. A status here says an address answered at a point in time. Stock, price and seller behaviour are separate questions that this site does not measure.

Why not rebuild every wrapped address I have?

Only the source marks this site has observed are mapped. Everything else is reported as read but not rebuilt, because a mapping that has not been verified produces confident wrong answers.

Do I need an account, or does this send my links anywhere?

No account, and nothing leaves the page. The reading happens in your browser.
