ExcelPrice Converter - скачка и преобразование документов Excel в нужный формат за три клика мышкой.
 |
Мне довольно часто приходится выполнять всякие преобразования документов EXCEL. Первые фрагменты различных преобразований на VBA на моем сайте сделаны в 2002-м году, хотя я начал работать на VBA еще в 1994 году. Различные преобразования прайс-листов приходится делать постоянно - например в 2005-2007 я работал в крупнейшей российской системой электронных магазинов digitalshop.ru. Там было много-много проблем, которые надо было решать, но самая массивная задача там была конвертация множества разнообразных прайс-листов различных поставщиков в единый формат. Задача собственно отображения уже уложенных в базу данных была вторична - это могли сделать любые web-мастера (каждый на своей Web-технологии). И на этой базе товаров были сделаны десятки и десятки электронных магазинов. При работе в режиме фриланса конвертация разнообразных прайс-листов в единый формат (например для последующей загрузки в базу) - это тоже самая распространенная задачка. И вот через 15 лет работы на VBA я решил опубликовать эту простую обвязку, которая позволяет в ТРИ КЛИКА МЫШКОЙ выполнить всю работу по преобразованию документов Excel . А при необходимости войти в плагин на VBA и поправить код конвертации. Прога публикуется именно в том виде - с которого она гнется в любую необходимую вам сторону наиболее легким способом. Я не стал обременять этот код функциями, которые возможно вам будут не нужны и которые будет трудно понять. |
1. Небольшая (и в общем в данной простейшей проге не особо нужная) обвязка для обращений к Экселу.

4. В качестве простейшего шаблонного кода в данном проекте лежит код VBA, который просто отрезает шапку и добавляет 5% к цене товара.

4: Dim SourceFileName As String, TargetFileName As String
5: SourceFileName = Workbooks(1).FullName
6: Set SourceSheet = Workbooks(1).ActiveSheet
7: '
8: Dim NewWorkBooks As Workbook
9: Set NewWorkBooks = Workbooks.Add
10: Set TargetSheet = NewWorkBooks.ActiveSheet
11: '
12: Dim i As Long, j As Long
13: For i = 19 To 20000
14: For j = 1 To 14
15: If j = 9 and IsNumeric(SourceSheet.Cells(i, j).Value) Then
16: TargetSheet.Cells(i - 18, j) = SourceSheet.Cells(i, j).Value * 1.05
17: Else
18: TargetSheet.Cells(i - 18, j) = SourceSheet.Cells(i, j)
19: End If
20: Next
21: Next
22: '
23: 'MsgBox "End converting"
24: '
25: TargetFileName = Replace(SourceFileName, ".", "_target.")
26: NewWorkBooks.SaveAs (TargetFileName)
27: End Sub
Excel вообще штука капризная и может потребоваться адаптация моей проги для ваших условий. Например в классе MSExcel может потребоваться изменить культуру потока (чтобы удовлетворить лицензионным ограничениям):
10: Public Sub New()
11: ExcelApplication = New Microsoft.Office.Interop.Excel.Application
12: Dim oldCI As System.Globalization.CultureInfo = System.Threading.Thread.CurrentThread.CurrentCulture
13: System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-US")
С 2010-м экселом моя прога работает если только устновить дополнительную глобальную галку в Excel и перезагрузиться после этого.
