Convert XML to LaTeX Online

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

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 LaTeX is

A LaTeX table is a tabular environment: a column specification, ampersands between cells and double backslashes at the end of each row.

Academic papers, theses and anything typeset with LaTeX or written in Overleaf.

What changes when you convert XML to LaTeX

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.

Rules are drawn with booktabs by default, which is what most journal templates expect. The characters LaTeX treats as special, & % $ # _ { }, are escaped so a value like 50% compiles instead of ending the line.

What carries over from XML to LaTeX

XML records 4 things about a table that LaTeX has no way to hold.

An empty cell and a missing one are the same thing in LaTeX, 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. LaTeX 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 LaTeX, so line breaks are replaced rather than carried through.

LaTeX 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.

LaTeX is the end of the line for this data. Reading the table back out of it is a separate and much harder problem than writing it, so keep the XML if you will need the values again.

The identifier 007 comes out of the LaTeX 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 LaTeX file goes wrong.

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

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.

    104 & Wei Chen & Manager & 2023-06-30 & 40 \\

Questions

How do I convert XML to LaTeX?

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

Why does my table not compile?

The usual cause is a missing package. Booktabs rules need \usepackage{booktabs} in the preamble. Switch the rules option off and the output uses plain \hline instead, which needs nothing.

Can I convert the LaTeX back to XML afterwards?

Not mechanically. LaTeX keeps how the table looks, not what it held, so going back means reading the values off the page again. Keep the XML if you will need it.

What happens to nested values?

LaTeX 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 LaTeX, 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.
