Hello,
I used this example:
https://p5js.org/reference/#/p5/saveTable
I edited it:
let table;
function setup() {
table = new p5.Table();
// table.addColumn('id');
//table.addColumn('species');
//table.addColumn('name');
//let newRow = table.addRow();
// newRow.setNum('id', table.getRowCount() - 1);
//newRow.setString('species', 'Panthera leo');
// newRow.setString('name', 'Lion');
// To save, un-comment next line then click 'run'
saveTable(table, 'new.csv');
}
// Saves the following to a file called 'new.csv':
// id,species,name
// 0,Panthera leo,Lion
It saves a csv file.
This works as well:
saveTable(table, 'new', 'csv');
Google Chrome was used along with https://editor.p5js.org/
