I'm currently running into an issue where I'll only get the titles of my columns showing for my table when using csvsimple with \csvautotabular. table problem

The current code I used to produce this is

    \csvautotabular[respect all]{test_utf8.csv}

I have used the test.csv

    Name,Battery %,Last updated
    L1 A / B (C),5%,"Sept. 1, 2021, 00:00 a.m."
    G D,12%,"Aug. 31, 2021, 9:09 a.m."
    L2 E / F (G),80%,"Feb. 21, 2021, 10:00 a.m."

which I believe has the general formatting required for my other csv files.

Two changes solve the problem:

  1. Changing \csvautotabular[respect all]{test_utf8.csv} to \csvautotabular[respect percent]{test_utf8.csv} (and other special characters that should be interpreted as normal characters).

  2. Hiding commas which are not separators:

    Name,Battery %,Last updated
    L1 A  B (C),5%,{Sept. 1, 2021, 0000 a.m.}
    G D,12%,{Aug. 31, 2021, 909 a.m.}
    L2 E  F (G),80%,{Feb. 21, 2021, 1000 a.m.}

Because you need curly braces to mask a block that may contain commas not to be processed as separators, you shouldn't choose respect all.

  • Thank you for the quick response. So besides the change of use for the respect function, it's just a formatting issue in the csv itself? Currently I'm pasting data into excel and removing what columns/rows I don't need and saving as .csv. There's probably a quick way to replace the quotation marks with curly braces before I save to import into TeX. Sep 1, 2021 at 6:52
  • @JacksonWright Yes, commas were used in two functions. If you are expecting many commas in your data, you can choose another separator in CSV files by, say, [separator=semicolon] as an option to \csvautobooktabular. Sep 1, 2021 at 6:57
  • @JacksonWright I have just corrected the wrong percent sings in my answer. They certainly should be commas. Sep 1, 2021 at 7:02
  • Cheers, the hardest part now is just getting a program to save it with curly brackets instead of quote marks hahaha :) Sep 1, 2021 at 7:12
  • @JacksonWright Or omitting quote marks with ; as a separator. Sep 1, 2021 at 7:21

I thought I would take this space to show off the recently added (v3.0 2021-08-08) capability of the readarray package to create tabulars. Because the file contains raw % tokens and uses quote grouping "...", I required a little more setup to digest it.

Basically, the \readdef macro places the contents of a file into a \def, while the \readarray macro places the contents of the \def into an array.

The \typesetarray macro is newly introduced, and uses helper macros named \typesetrowsepchar, \typesetcolsepchar (also \typesetplanesepchar for 3-D) to format the typeset, as they are inserted between rows, columns, and/or planes.

EDITED to place the catcode stuff in its own macro, easing the burden on invocation setup. Thus, the \readdef invocation is replaced with \readdefquotespercents in order to automatically digest raw % tokens as characters and to use quote-grouping.

RE-EDITED to use \lowercase magic to define the active character " inside of a macro.

  \catcode`\%=12 \readdef{#1}#2\catcode`\%=14 
  \edef\tabdata{\tabdata}% CONVERT QUOTED PHRASES

\readarray\tabdata\tabarray[-,\ncols]% PLACE def INTO ARRAY

LaTeX Error: Command \typesetcolsepchar undefined. Undefined control sequence. ! Use of \tabarray doesn't match its definition. l.28 \typesetarray\tabarray\\ Sep 3, 2021 at 5:27
  • @JacksonWright The readarray package seems outdated. The one needed was released a month ago, [2021-08-08], v3.0 Sep 3, 2021 at 11:40
