Convert LaTeX to ActionScript Online

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

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 ActionScript is

An ActionScript Array of object literals.

Legacy Flash and AIR projects.

What changes when you convert LaTeX to ActionScript

The tabular body is read, rules are dropped, and escaped characters are unescaped. Text wrapped in textbf or emph is reduced to the text itself.

Typed as Array, with double-quoted string values.

What carries over from LaTeX to ActionScript

LaTeX records 2 things about a table that ActionScript has no way to hold.

ActionScript wants a type for each column, and LaTeX does not record one, so each column is typed from what its values look like. A column of digits that should stay text - a zip code, a phone number, a leading-zero id - is the usual thing to check afterwards.

ActionScript has no header row. The column names are repeated as keys on every record instead, which is why the result is bigger on disk than the table it came from.

Anything visual in the LaTeX - weight, alignment, colour, column widths - has no counterpart in ActionScript and is dropped. The values are what survives.

This is the direction that recovers structure: LaTeX has no table in it to read, only an arrangement that looks like one, so the rows and columns are inferred rather than read.

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

The quotes around Jonah "Jo" Pryce are escaped with a backslash in the ActionScript.

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.

LaTeX in
\begin{tabular}{lllll}
  \toprule
  id & name & role & started & hours \\
  \midrule
  007 & Halima Yusuf & Analyst, data & 2024-03-15 & 38.5 \\
  012 & Jonah "Jo" Pryce & Engineer & 2025-11-02 &  \\
  104 & Wei Chen & Manager & 2023-06-30 & 40 \\
  \bottomrule
\end{tabular}
ActionScript out
var staff:Array = [
  {id: "007", name: "Halima Yusuf", role: "Analyst, data", started: "2024-03-15", hours: "38.5"},
  {id: "012", name: "Jonah \"Jo\" Pryce", role: "Engineer", started: "2025-11-02", hours: ""},
  {id: "104", name: "Wei Chen", role: "Manager", started: "2023-06-30", hours: "40"},
];

Questions

How do I convert LaTeX to ActionScript?

Paste your LaTeX into the box above or drop the file onto it. Check the table in the grid, then copy or download the ActionScript 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.

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.
