Convert LaTeX to ASP Online

Paste a LaTeX table below, edit it if you need to, and get ASP 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 ASP is

A two-dimensional VBScript array with one assignment per cell.

Classic ASP applications.

What changes when you convert LaTeX to ASP

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.

Dimensioned to the exact size of the table, then filled cell by cell.

What carries over from LaTeX to ASP

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

ASP 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.

LaTeX can hold a value that is itself a list or an object. ASP 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 ASP, so line breaks are replaced rather than carried through.

ASP 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 ASP 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 ASP 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 ASP file goes wrong.

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

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}

ASP out

Dim staff(3, 4)
staff(0, 0) = "id"
staff(0, 1) = "name"
staff(0, 2) = "role"
staff(0, 3) = "started"
staff(0, 4) = "hours"
staff(1, 0) = "007"
staff(1, 1) = "Halima Yusuf"
staff(1, 2) = "Analyst, data"
staff(1, 3) = "2024-03-15"
staff(1, 4) = "38.5"
staff(2, 0) = "012"
staff(2, 1) = "Jonah \"Jo\" Pryce"
staff(2, 2) = "Engineer"
staff(2, 3) = "2025-11-02"
staff(2, 4) = ""
staff(3, 0) = "104"
staff(3, 1) = "Wei Chen"
staff(3, 2) = "Manager"
staff(3, 3) = "2023-06-30"
staff(3, 4) = "40"

Questions

How do I convert LaTeX to ASP?

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

What happens to nested values?

ASP has no nested cell, so a list or object inside a LaTeX 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 ASP, 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.
