CSV to HTML translation
From Rosetta Code
You are encouraged to solve this task according to the task description, using any language you may know.
Consider a simplified CSV format where all rows are separated by a newline and all columns are separated by commas. No commas are allowed as field data, but the data may contain other characters and character sequences that would normally be escaped when converted to HTML
The task is to create a function that takes a string representation of the CSV data and returns a text string of an HTML table representing the CSV data. Use the following data as the CSV text to convert, and show your output.
- Character,Speech
- The multitude,The messiah! Show us the messiah!
- Brians mother,<angry>Now you listen here! He's not the messiah; he's a very naughty boy! Now go away!</angry>
- The multitude,Who are you?
- Brians mother,I'm his mother; that's who!
- The multitude,Behold his mother! Behold his mother!
For extra credit, optionally allow special formatting for the first row of the table as if it is the tables header row (via <thead> preferably; CSS if you must).

[edit] Go
Minimalist version satisfies basic task requirements:
package main
import (
"bytes"
"fmt"
"strings"
"text/template"
)
func main() {
fmt.Print(csvToHtml(`Character,Speech
The multitude,The messiah! Show us the messiah!
Brians mother,<angry>Now you listen here! He's not the messiah; he's a very naughty boy! Now go away!</angry>
The multitude,Who are you?
Brians mother,I'm his mother; that's who!
The multitude,Behold his mother! Behold his mother!`))
}
func csvToHtml(csv string) string {
lines := strings.Split(csv, "\n")
data := make([][]string, len(lines))
for i, l := range lines {
data[i] = strings.Split(l, ",")
}
var b bytes.Buffer
template.Must(new(template.Template).Parse(`<table>
{{range .}} <tr>{{range .}}<td>{{html .}}</td>{{end}}</tr>
{{end}}</table>
`)).Execute(&b, data)
return b.String()
}
Extra credit version interprets "optionally" with a command line option. When running the compiled program, a command line option of -h does the special formatting for the heading line.
Also different in this version, the csv package is used to parse the input. It offers little advantage for the simple data of the task, but becomes nice for real problems.
A data structure with named fields is used. Again, maybe frivolous for this task, but it helps organize larger problems.
The html/template package is used instead of text/template. This adds protection against code injection attacks.
Finally, the template definition contains three templates, showing how templates can be composed.
package main
import (
"bytes"
"encoding/csv"
"errors"
"flag"
"fmt"
"html/template"
)
const csvIn = `Character,Speech
The multitude,The messiah! Show us the messiah!
Brians mother,<angry>Now you listen here! He's not the messiah; he's a very naughty boy! Now go away!</angry>
The multitude,Who are you?
Brians mother,I'm his mother; that's who!
The multitude,Behold his mother! Behold his mother!`
func main() {

[edit] Solution #2: MarkupBuilder
A much cleaner solution using the Groovy XML MarkupBuilder class. It solves both the basic and extra credit tasks.
import groovy.xml.MarkupBuilder
def formatRow = { doc, row ->
doc.tr { row.each { cell -> td { mkp.yield(cell) } } }
}
def formatPage = { titleString, csv, header=false ->
def writer = new StringWriter()
def doc = new MarkupBuilder(writer)
def rows = csv.split('\n').collect { row -> row.split(',') }
doc.html {
head {
title (titleString)
style (type:"text/css") {
mkp.yield('''
td {background-color:#ddddff; }
thead td {background-color:#ddffdd; text-align:center; }
''')
}
}
body {
table {
header && thead { formatRow(doc, rows[0]) }
header && tbody { rows[1..-1].each { formatRow(doc, it) } }
header || rows.each { formatRow(doc, it) }
}
}
}
writer.toString()
}
Test:
The interface is the same for both solutions, so we just reuse the same test as before.
Basic output:
<html>
<head>
<title>Basic</title>
<style type='text/css'>
td {background-color:#ddddff; }
thead td {background-color:#ddffdd; text-align:center; }

[edit] Icon and Unicon
This solution for the extra credit works in both Icon and Unicon. The simple CSV is read from standard input and written to standard output. The presence/abscend of "-heading" in the argument list sets the variable thead to the procedure writes or a 1 (for more on this see Introduction to Icon/Unicon - Conjunction yielding different results).
procedure main(arglist)
pchar := &letters ++ &digits ++ '!?;. ' # printable chars
write("<TABLE>")
firstHead := (!arglist == "-heading")
tHead := write
while row := trim(read()) do {
if \firstHead then write(" <THEAD>") else tHead(" <TBODY>")
writes(" <TR><TD>")
while *row > 0 do
row ?:= ( (=",",writes("</TD><TD>")) |
writes( tab(many(pchar)) |
("&#" || ord(move(1))) ), tab(0))
write("</TD></TR>")
if (\firstHead) := &null then write(" </THEAD>\n <TBODY>")
tHead := 1
}
write(" </TBODY>")
write("</TABLE>")
end
Output:
<TABLE>
<THEAD>
<TR><TD>Character</TD><TD>Speech</TD></TR>

[edit] MATLAB
The easiest way to import csv data into MATLAB is to save it in a csv file, then import the data using the "uiimport -file" command. The result of which will be a cell array with each entry being a string delimited by the newline character.
Example:
>> data
data =
'Character,Speech'
'The multitude,The messiah! Show us the messiah!'
[1x109 char]
'The multitude,Who are you?'
'Brians mother,I'm his mother; that's who!'
'The multitude,Behold his mother! Behold his mother!'
The other way is to copy and paste the data, but you will have to manually add all of the newline characters and string quotations your self. This is messy and infeasible for large amounts of data, but it is still a valid input.
Example:
>> csvData = ['Character,Speech' sprintf('\n')...
'The multitude,The messiah! Show us the messiah!' sprintf('\n')...
'Brians mother,<angry>Now you listen here! He''s not the messiah; he''s a very naughty boy! Now go away!</angry>' sprintf('\n')...
'The multitude,Who are you?' sprintf('\n')...
'Brians mother,I''m his mother; that''s who!' sprintf('\n')...
'The multitude,Behold his mother! Behold his mother!']
csvData =
Character,Speech
The multitude,The messiah! Show us the messiah!
Brians mother,<angry>Now you listen here! He's not the messiah; he's a very naughty boy! Now go away!</angry>
The multitude,Who are you?
Brians mother,I'm his mother; that's who!
The multitude,Behold his mother! Behold his mother!
So, to be able to accept both type of inputs, the function "csvToHTHML()" tests to see if the input is a string as in example 2. If the input is a string it converts the data to a cell array of strings formatted in the exact same way MATLAB formats the first example. The output of the function will be a properly formatted HTML table, which includes the "<THEAD>" around the first row of data so that special formatting can be applied to the column titles.
function htmlOutput = csvToHTML(csvData)
if ischar(csvData)
newlineIndex = find( (csvData == char(10)) ); %find all newline characters
text = cell( numel(newlineIndex),1 ); %preallocate space for processed data
for i = (numel(newlineIndex):-1:1) %iterate backwards
text{i} = csvData(newlineIndex(i)+1:end);
csvData(newlineIndex(i):end) = []; %delete the newline and everything after it
end
csvData = text;
clear text;
end
htmlOutput = '<table>';
for i = (1:numel(csvData))
if i == 1 %If first entry, then include <thead>
csvData{i} = [char(10) char(9) '<thead><tr>' char(10) char(9) char(9) '<td>'...
csvData{i} '</td>' char(10) char(9) '</tr></thead>' char(10)];
else %Otherwise, the data is a regular table row
csvData{i} = [char(9) '<tr>' char(10) char(9) char(9) '<td>' csvData{i}...
'</td>' char(10) char(9) '</tr>' char(10)];
end %if
%Convert each comma to its HTML equivalent
for j = fliplr(find( (csvData{i} == ',') ))
csvData{i} = [csvData{i}(1:j-1) '</td>' char(10) char(9) char(9) '<td>' csvData{i}(j+1:end)];
end %for
%We could make this faster by preallocating htmlOutput but that is
%more work than necessary to provide a basic solution
htmlOutput = [htmlOutput csvData{i}];
end %for
htmlOutput = [htmlOutput '</table>'];
end %csvToHTML
Ouput:

[edit] Perl
Provide the CSV data as standard input. With a command-line argument, the first row will use <th> instead of <td>.
use HTML::Entities;
sub row {
my $elem = shift;
my @cells = map {"<$elem>$_</$elem>"} split ',', shift;
print '<tr>', @cells, "</tr>\n";
}
my ($first, @rest) = map
{my $x = $_; chomp $x; encode_entities $x}
<STDIN>;
print "<table>\n";
row @ARGV ? 'th' : 'td', $first;
row 'td', $_ foreach @rest;
print "</table>\n";

The extra credit version has one extra line compared to the non-extra credit version. To output a header, simply add "header" to the command line:
ruby csv2html.rb header
I/O is done through standard input/output.

def row2html str, wrap = "td"
"<tr>" +
str.split(",").map { |cell| "<#{wrap}>#{CGI.escapeHTML cell}</#{wrap}>" }.join +
"</tr>"
