Let's say I have a table like

table

which I save as a .csv

and then import with latex like so:

\usepackage{adjustbox}
\usepackage{booktabs,csvsimple}

[...]

\begin{table}[ht]
\begin{adjustbox}{max width=0.9\textwidth}
\csvautobooktabular[]{csvs/test.csv}
\end{adjustbox}
\caption{blah blah blah etc.}
\label{tab:IRTL}
\end{table}

This won't compile (see error message below).

But if I move the formulae from the header cells to some other cells, e.g.

experiment,N,Z[ms],X[requests/ms],R [ms],N/X-Z,difference[ms],rel.difference
S=3 write-to-1,690,0,15.0258730823,47.8550460251,45.9207925038,-1.9342535213,-4.0419008693

things work fine:

So I guess this has something to do with the way autobooktabular is treating the headers.

How do I get the table to parse the headers correctly?

I've inserted something that you may have forgotten.

With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.
! Extra \endcsname.

I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

It seems \frac is too fragile to put it in a header that is interpreted by the csv reader. You could change the header entry to N/X-Z and then specify the nice header yourself.

\csvautobooktabular[table head={\toprule  experiment &  N &  Z[ms] &  X[requests/ms] &  R [ms] & $\frac{N}{X}-Z$ & difference[ms] & rel.difference \\\midrule}]{table.csv}
