Convert LaTeX to CSV Online

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

CSV is a text file where each line is a row and commas separate the fields. There is no type system, no formatting and no second sheet. Every value is text until something downstream decides otherwise.

Almost every database, analytics tool and spreadsheet can read and write it, which is why exports default to it.

What changes when you convert LaTeX to CSV

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.

Any value containing the delimiter, a quote or a line break gets wrapped in quotes, and embedded quotes are doubled. That is the rule in RFC 4180 and it is what spreadsheet software expects.

What carries over from LaTeX to CSV

LaTeX records 3 things about a table that CSV has no way to hold.

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

CSV has no separate idea of a header, so the column names become an ordinary first row and nothing in the file marks them as different from the data.

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

The result can be read a record at a time, and appended to by adding to the end of it. That is worth having for a table too large to hold in memory, and it means a CSV file that is cut off part way through still gives you every record before the cut.

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 CSV 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 CSV file goes wrong.

The quotes around Jonah "Jo" Pryce are doubled, which is how the delimited formats escape a quote in the CSV.

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}

Questions

How do I convert LaTeX to CSV?

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

Why does my CSV open with all the data in one column?

The file uses a delimiter your spreadsheet did not expect. Exports from European locales often use semicolons because the comma is the decimal separator there. Change the delimiter in the export options and the columns split correctly.

What happens to nested values?

CSV 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.
