    <p>Here is the process, I have an xlsm file called template, inside a worksheet called data. Then I have 5 Csv files, I must put the content of all csv file inside the data worksheet.</p> <p>No problems to do that, except if a date is "07/09/12" it will become "09/07/12" in excel.</p> <p>So I have a list called data, here is a print of one of it's line</p> <pre><code>['07/09/12', 'LARO', 'MEDITERRAN', '245', 'UZES', '11', '0', '0', '0', '0', '11', '0'] </code></pre> <p>I'm putting the in the excel file with this piece of code :</p> <p>First I open the file (xl is because I use "with self as xl")</p> <pre><code>def open(self): self.xl.Visible = 1 self.xl.ScreenUpdating = False self.worksheet = self.xl.Workbooks.Open(self.getOutputFile()) </code></pre> <p>Then I erase the data worksheet</p> <pre><code>def cleanData(self): sheet = self.xl.Sheets(self.sheetName) def findNumberOfLines(start_line): nb = 0 while sheet.Cells(start_line + nb, self.startColumn).Value is not None: nb += 1 return nb </code></pre> <p>Then I fill the data</p> <pre><code>def fillData(self): sheet = self.xl.Sheets(self.sheetName) noRow = self.startLine for row in self.data: noCol = self.startColumn for i, value in enumerate(row): sheet.Cells(noRow, noCol).Value = value noCol+=1 noRow+=1 </code></pre> <p>And I save</p> <pre><code>def save(self): self.worksheet.Save() </code></pre> <p>And everythong is good except the day and month are inverted inside excel (it's not displaying US format, it's displaying EUR format with month and day inverted (3 october becomes 9 march, tested using "long date" format)</p> <p>Weird thing : the excel cell containing dates is set at "standard" but once it has been filed by my python script it's set at "date"</p> <p><strong>WORKAROUND</strong> when filling the sheet I'm intercepting every date and converting them to datetime, excel seems to like that</p> <pre><code>def fillData(self): sheet = self.xl.Sheets(self.sheetName) noRow = self.startLine pattern = re.compile('^\d+/\d+/\d+$') for row in self.data: noCol = self.startColumn for i, value in enumerate(row): if (pattern.match(str(value))): date = value.rsplit('/') sheet.Cells(noRow, noCol).Value = datetime(int(date[2]), int(date[1]), int(date[0])) else: sheet.Cells(noRow, noCol).Value = value noCol+=1 noRow+=1 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
