Convert LaTeX to R DataFrame Online

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

R code that builds a data.frame from character vectors.

Statistics and R notebooks.

What changes when you convert LaTeX to R DataFrame

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.

stringsAsFactors is set to FALSE explicitly. It has defaulted to FALSE since R 4.0, but being explicit means the snippet behaves the same on older installs.

What carries over from LaTeX to R DataFrame

LaTeX records 2 things about a table that R data frame has no way to hold.

R data frame 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. R data frame has only flat cells, so nested values are flattened into one cell rather than being spread across columns.

Anything visual in the LaTeX - weight, alignment, colour, column widths - has no counterpart in R data frame 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 R DataFrame 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 R DataFrame file goes wrong.

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

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}
R DataFrame out
staff <- data.frame(
  id = c("007", "012", "104"),
  name = c("Halima Yusuf", "Jonah \"Jo\" Pryce", "Wei Chen"),
  role = c("Analyst, data", "Engineer", "Manager"),
  started = c("2024-03-15", "2025-11-02", "2023-06-30"),
  hours = c("38.5", "", "40")
  , stringsAsFactors = FALSE
)

Questions

How do I convert LaTeX to R DataFrame?

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

R data frame 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.

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.
