Datatable export to Excel Format Problems with random columns

i am trying to export data from a datatable to an excel file.
But everytime i use the excel button it changes the format of my numbers.
For example a 0,023 is copied to excel as a 23.
Is there a way to use the excel export button so that excel isnt changing the format?
The other things is that i use the datatable on different data from a DB. So the column isnt always the same which has to be formated. Even the User can select which column should be exported. So the Format sould be used.
So possible Datatable could look like:
A
B
C
abc
1
1,2
A
B
C
abc
1,2

DataTable limited rows

I have data in my SQLite table and it has 985 rows, so I used DataTable to organise (searching and export to Pdf, CSV...), the problem is that the DataTable is limited rows and just shows the first 200 rows!.
my code is
<script>
$(document).ready( function () {
$('#table_id').DataTable({
dom: 'B<"clear">lfrtip',
buttons: {
name: 'primary',
buttons: [ 'copy', 'csv', 'excel', 'pdf' ]
}
});
});
</script
the data is stored in table Sqlite
and in the HTML page:
so what's the solution with?

There is more than one option for this:
You can use the paging option and set it to false, or you can use the pageLength option to choose how many results you want to show on one page.
paging:
<script>
$(document).ready( function () {
$('#table_id').DataTable({
dom: 'B<"clear">lfrtip',
paging: false,
buttons: {
name: 'primary',
buttons: [ 'copy', 'csv', 'excel', 'pdf' ]
}
});
});
</script
pageLength:
<script>
$(document).ready( function () {
$('#table_id').DataTable({
"pageLength": 1000,
dom: 'B<"clear">lfrtip',
buttons: {
name: 'primary',
buttons: [ 'copy', 'csv', 'excel', 'pdf' ]
}
});
});
</script

JavaScript/JQuery DataTables - Inserting tools (PDF,Copy,CSV, Print) with Existing JQuery code

I have an existing JQuery code for DataTable which lets the hidden first column be in order of Descending.
<script>
$(document).ready(function() {
$('#dataTables-example').DataTable( {
order:[[0,"desc"]],
"columnDefs": [
{
"targets": [ 0 ],
"visible": false,
"searchable": false
}
]
} );
} );
</script>
And I want to add this lines of codes, which I copied from DataTables.net
$(document).ready(function() {
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
]
} );
} );
How should it be done? I tried doing this:
<script>
$(document).ready(function() {
$('#dataTables-example').DataTable( {
order:[[0,"desc"]],
"columnDefs": [
{
"targets": [ 0 ],
"visible": false,
"searchable": false
}
],
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
]
} );
} );
</script>
But it won't work. Can someone help me correct the format?
I would like to add another relevant information to be added too. On the Print button as well as PDF button, I would like it to be in Landscape mode and with Added custom message. Like this:
extend: 'pdfFlash',
messageTop: 'PDF created by Buttons for DataTables.'
Can someone help me with this? Thank you.

You need to create array of buttons, try this way
$(document).ready(function () {
$('#dataTables-example').DataTable({
order: [[0, "desc"]],
"columnDefs": [
{
"targets": [0],
"visible": false,
"searchable": false
}
],
dom: 'Bfrtip',
buttons: [
{ extend: 'copy' },
{ extend: 'csv' },
{ extend: 'excel' },
{ extend: 'pdf', title: 'ExampleFile' },
{ extend: 'print' }
]
});
});

Datatables with requirejs $(...).DataTable is not a function

I have problem when I load data-tables with requirejs.
Following is my code
require.config({
paths: {
"datatables" : "https://cdn.datatables.net/u/dt/jq-2.2.3,jszip-2.5.0,pdfmake-0.1.18,dt-1.10.12,b-1.2.1,b-colvis-1.2.1,b-flash-1.2.1,b-html5-1.2.1,b-print-1.2.1,fc-3.2.2,fh-3.1.2,r-2.1.0,sc-1.4.2,se-1.2.0/datatables.min",
}
});
requirejs( ["datatables"], function() {
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf'
]
});
});
I have generated datatables.min.js from the following link:
https://www.datatables.net/download/
Already included the jquery and other extensions, but I got this error:
$(...).DataTable is not a function
Can anyone help me?

You should use Jquery ready function, for example :
requirejs( ["datatables"], function() {
$(function(){ // ready function
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf'
]
});
});
});
