Convert XML to Trac Wiki Online

Paste an XML table below, edit it if you need to, and get Trac Wiki back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

From

The only part of this site that uses a server. The address is sent to it so the page can be fetched, because a browser is not allowed to fetch someone else's page itself. Your own files are never involved.

Nothing here is uploaded. The parsing happens on this page.

What XML is

XML marks up data with nested named tags and optional attributes. It is verbose, strict about being well-formed, and can carry a schema that says what shape a document must have.

Enterprise integrations, government data feeds, RSS, SOAP services and older document formats.

What Trac Wiki is

Trac wiki tables use double pipes around every cell.

Projects still running a Trac instance.

What changes when you convert XML to Trac Wiki

The first repeating element is treated as the rows. Attributes are read alongside child elements and prefixed so they do not collide with a same-named tag. Nesting one level deep becomes dotted column names; deeper structures are kept as text.

Every cell is wrapped in double pipes, which is the whole syntax.

What carries over from XML to Trac Wiki

XML records 3 things about a table that Trac wiki has no way to hold.

An empty cell and a missing one are the same thing in Trac wiki, so a null and an empty string in the XML both come out blank and can no longer be told apart.

XML can hold a value that is itself a list or an object. Trac wiki has only flat cells, so nested values are flattened into one cell rather than being spread across columns.

A line break inside a cell ends the row in Trac wiki, so line breaks are replaced rather than carried through.

Trac wiki marks header cells differently from data cells, so the keys are lifted out and written once as a marked header row rather than repeated on every row.

The identifier 007 comes out of the Trac Wiki as 007. Reading it as a number would have made it 7, and an id that changes value is worse than one that stays text.

The role "Analyst, data" survives with its comma, in one cell rather than split across two. That is the first thing to check in any converted table, and the usual place a Trac Wiki file goes wrong.

The quotes around Jonah "Jo" Pryce are left as a plain quote character in the Trac Wiki.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert XML to Trac Wiki?

Paste your XML into the box above or drop the file onto it. Check the table in the grid, then copy or download the Trac Wiki from the output panel. It takes one step and the data never leaves your browser.

What happens to nested values?

Trac wiki has no nested cell, so a list or object inside a XML value is flattened into a single cell rather than expanded into extra columns. Split it before converting if the parts need to be separate.

One of my cells has a line break in it - what happens?

A line break would end the row in Trac wiki, so it is replaced instead of carried through. The rest of the cell stays where it belongs.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
