Esse tópico é de 2007.
Caso não tenha achado ainda uma solução, é possível da seguite forma:
1) Utilizando o Google-Drive e uma planilha do google para capturar as cotacoes. Por exemplo a planilha abaixo:
https://docs.google.com/spreadsheets/d/ ... sp=sharing
2) gravando um script dentro dessa planilha em Ferramentas->Editor de Scripts para permitir que o google salve automaticamente como um arquivo CSV em determinado periodo de tempo.
Script
function onOpen() {
SpreadsheetApp.flush();
var ss = SpreadsheetApp.getActiveSpreadsheet();
//var csvMenuEntries = [{name: "export as csv files", functionName: "saveAsCSV"}];
//ss.addMenu("csv", csvMenuEntries);
saveAsCSV();
};
function saveAsCSV() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ss.getSheets();
// create a folder from the name of the spreadsheet
//var folder = DriveApp.createFolder(ss.getName().toLowerCase().replace(/ /g,'_') + '_csv_' + new Date().getTime());
if(checkFolder('exp_cotacoes') == true){
var folder = DriveApp.getFoldersByName('exp_cotacoes').next();
}else{
var folder = DriveApp.createFolder('exp_cotacoes');
}
//Browser.msgBox(ss.getName().toLowerCase().replace(/ /g,'_') + '_csv_' + new Date().getTime());
for (var i = 0 ; i < sheets.length ; i++) {
var sheet = sheets[i];
// append ".csv" extension to the sheet name
fileName = sheet.getName() + ".csv";
// convert all available sheet data to csv format
var csvFile = convertRangeToCsvFile_(fileName, sheet);
// create a file in the Docs List with the given name and the csv data
while(checkFile(folder,fileName) == true){
var folder_aux = folder.getFilesByName(fileName);
folder.removeFile(folder.getFilesByName(fileName).next());
}
folder.createFile(fileName, csvFile);
}
//Browser.msgBox('Files are waitig in a folder named ' + folder.getName());
}
function convertRangeToCsvFile_(csvFileName, sheet) {
// get available data range in the spreadsheet
var activeRange = sheet.getDataRange();
try {
var data = activeRange.getValues();
var csvFile = undefined;
// loop through the data in the range and build a string with the csv data
if (data.length > 1) {
var csv = "";
for (var row = 0; row < data.length; row++) {
for (var col = 0; col < data[row].length; col++) {
if (data[row][col].toString().indexOf(",") != -1) {
data[row][col] = "\"" + data[row][col] + "\"";
}
}
// join each row's columns
// add a carriage return to end of each row, except for the last one
if (row < data.length-1) {
csv += data[row].join(",") + "\r\n";
}
else {
csv += data[row];
}
}
csvFile = csv;
}
return csvFile;
}
catch(err) {
Logger.log(err);
Browser.msgBox(err);
}
}
function checkFolder(filename){
var results;
var haBDs = DriveApp.getFoldersByName(filename)
//Does not exist
if(!haBDs.hasNext()){
results = haBDs.hasNext();
}
//Does exist
else{
results = haBDs.hasNext();
}
Logger.log(results)
return results;
}
function checkFile(folder,filename){
var results;
var haBDs = folder.getFilesByName(filename);
//Does not exist
if(!haBDs.hasNext()){
results = haBDs.hasNext();
}
//Does exist
else{
results = haBDs.hasNext();
}
Logger.log(results)
return results;
}
No script acima o arquivo csv sera gravado na pasta do usuario\Google Drive\exp_cotacoes
3) aí basta ler os dados do arquivo CSV e importar para o seu programa.
Terá algo, parecido com isso:
