Convert Excel to LaTeX Online

Paste an Excel 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.

What Excel is

An Excel workbook is a zip archive of XML parts describing sheets, cells, formulas, styles and charts. The .xlsx extension is that format; .xls is the older binary one from before 2007.

Finance, operations and anyone who received a file from finance or operations.

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 Excel to LaTeX

Only the first sheet is read, and cells are read as the text Excel displays rather than the number underneath. That matters for dates: a cell showing 15/03/2026 arrives as that string, not as a serial number you would then have to decode.

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 Excel to LaTeX

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

Excel distinguishes a number from the text of a number; LaTeX does not, so every value arrives as text and has to be re-parsed by whatever reads it next.

An empty cell and a missing one are the same thing in LaTeX, so a null and an empty string in the Excel both come out blank and can no longer be told apart.

A line break inside a cell ends the row in LaTeX, so line breaks are replaced rather than carried through.

LaTeX marks its header cells differently from its data cells, so the first row is written with that marker.

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 Excel if you will need the values again.

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.

Questions

How do I convert Excel to LaTeX?

Paste your Excel 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.

Does converting to Excel keep my formulas?

No. A table has values, not formulas. If your source came from Excel in the first place, the formulas were already resolved to their results before they reached this page. Anything that was =SUM(A1:A10) arrives as the number it produced.

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 Excel 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 Excel if you will need it.

Will my numbers still be numbers?

They will read the same, but LaTeX stores them as text. Anything that sorts or sums the result will need to parse them first, and a leading zero or a currency symbol is the usual place that goes wrong.

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.
