Automatic updating in excel
Could a macro be used to update our workbook links automatically on a periodic basis?
A: I would not recommend a macro approach to solving this problem.
Option Explicit Const cst Folder = "C:\Users\ATC0155\Documents\Toolbox\Excel08 20 selfupdate" Const cst Cols = 5 Sub Do Update() Dim wks As Worksheet Dim str File As String Dim app Excel As Excel.
You could add this as a Workbook_Open event to make sure it is correct every time the workbook is opened but I will let you worry about those sort of things. Open cst Folder & "\" & str File lng Row = lng Row 1 app Excel.
Instead, you should enable automatic link updates in Excel 2013 by selecting File, Options, Trust Center, Trust Center Settings, External Content, and under the section labeled Security settings for Workbook Links, select Enable automatic update for all Workbook Links, and then click OK.
Because this action grants automatic “write permissions” to all workbooks, Microsoft does not recommend this setting (because this setting is riskier as it removes the security barrier requiring users to manually authorize updates); but if you are confident that all of your workbooks are safe, this setting adjustment may help resolve your link update issues.

Excel shines at turning your data into charts—graphical representations of your data.
You can easily create a chart based on a range of data in a worksheet.
Application Dim lng Row As Long ' Prepare the sheet to receive the data Set wks = Sheet1 wks. Clear Contents ' Run through each file in the folder str File = Dir(cst Folder & "\*.xls*") lng Row = 0 Do While str File <> "" If str File <> Active Workbook. Open cst Folder & "\" & str File lng Row = lng Row 1 app Excel.
Name Then Set app Excel = Create Object(" Excel.
Application Dim lng Row As Long ' Prepare the sheet to receive the data Set wks = Sheet1 wks. Clear Contents ' Run through each file in the folder str File = Dir(cst Folder & "\*.xls*") lng Row = 0 Do While str File Active Workbook.
However, if you want to set the iteration options, you must use the Formulas page on the Word Options dialog box.
Excel 2013 has a multi-threading feature that allows you to reduce the time it takes to calculate complex formulas.
