links, find external references in a workbook

There is no automatic way to find external references (also called links) that are used in a destination workbook. However, external references use brackets [ ] to enclose the source workbook name when the workbook is closed, for example =SUM([Budget.xls]Annual!C10:C25), so you can use those characters to locate external references.

To find all external references in a destination workbook, you need to look in cells, names, objects (such as a text box or shape), chart titles, and chart data series.

Find external references that are used in cells

1. Close all source workbooks, and then open the destination workbook.
2. On the Home tab, in the Editing group, click Find & Select, and then click Find.

The Find and Replace dialog box is displayed.

3. Click Options.
4. In the Find what box, enter [.
5. In the Within box, click Workbook.
6. In the Look in box, click Formulas.
7. Click Find All.
8. In the list box that is displayed, look in the Formula column for formulas that contain [.

 Tip   Click the Formula column header to sort the column, and to group all of the external references together.

9. To select the cell with an external reference, select the row in the list box.

Links are also found in names, objects (such as a text box or shape), chart titles, and chart data series.  More info.

macros – in the “C:\Program Files\Microsoft Office\OFFICE11\XLSTART” folder the macros reside in “personal.xls”

Hide the file in Excel (Window menu, Hide command).

You keep personal.xls hidden unless you want to add macros to it. Whenever you start Excel, personal.xls opens automatically and runs in the background. If you don't hide the file, Excel opens it and allows you to add data to it.

If everything looks OK but the dang thing still doesn’t work from your shortcut key, look under Help|About MS Excel, you'll see a button called:  "Disabled Items...".  Check under there to see if it's marked not to open.  You can enable it there.

mod function - Returns the remainder after a number (dividend) is divided by another number (divisor)

number – convert to text

if you have the “new” version (Excel 2007, 2010) which ends in “.xlsx”, then you can use one of the following 2 methods:

using the Format > Cells > Number > Text command.

Highlight the column of numbers and use the Data > Text to Columns command. In Page 1 of the wizard, choose the appropriate file type (this will probably be Delimited). In Page 2, remove any column dividers that may have shown up to keep the data in one column. In Page 3, click Text under Column data format to indicate that this column is text.

But if you have the “old” version (Excel 2003 and before) which ends in “.xls”, then you must use this somewhat more cumbersome process:

1. Use the TEXT function

• Insert a temporary blank column B.
• In cell B2, enter this formula:

=TEXT(A2,"0")

• Fill the formula in B2 down to B3:B100.
• You need to change the formulas to values in order to have them become text. Highlight cells B2:B100.
• Use Ctrl+C to copy, then click Edit > Paste Special > Values > OK.
• The entries in column B will now be text versions of the numbers in column A.
• Copy column B back into column A.
• Delete the temporary column B.

pivot table - I usually start by highlighting the cells I want to tabulate - with field headings included up top.  Then, from the menu up top, insert tab, pivot table (extreme left).  Click where you want put the table (I often keep it in the same data sheet).  Then click anywhere in the little template that'll magically appear embedded in your sheet starting with the cell you picked.  A "PivotTable Field List" should pop up to the right as a dockable window.  You should have fields available at top of that window.  Drag whichever field you want to be your row or column labels at the bottom.  Then drag the field that holds your detail values into the Values pane.  Default is count which is usually worthless for me.  Maybe you want sum instead.  Click the "Sum of [field name]" pick list in that pane, you'll see a "Value Field Settings..." toward the bottom of that pick list.  Click that and a pop-up with ability to change from "count" to "sum".

split alternative to text to columns – - examples below assume text with multiple spaces and we're splitting on spaces but there are extra, extraneious spaces and we need to get stuff only at the end, etc.

split column at first space delimiter only (from here)

If you are only going to split into 2 cells then you could put this formula in the first cell to return the first part:
  =LEFT(A1,FIND(" ",A1,1)-1)
and this formula in the next cell to return the right-hand remainder
  =RIGHT(A1,LEN(A1)-FIND(" ",A1,1))

Extract the last substring from a cell - This works, even when there's stuff in the middle (like middle names) (from here):

=MID(A1,FIND(CHAR(1),SUBSTITUTE(A1," ",CHAR(1),LEN(A1)-LEN(SUBSTITUTE(A1," ",))))+1,LEN(A1))

or an alternate (from here) that puts the last chunk of text in column C:

C1 =TRIM(RIGHT(SUBSTITUTE(A1," ",REPT(" ",LEN(A1))),LEN(A1)))

and which has the added bonus of being able to get all the stuff up to that last space into column B:

B1 =LEFT(A1,LEN(A1)-LEN(C1)-1)

If you want everything but the last of several space-separated entries (from here)

  =LEFT(A1,FIND(?,SUBSTITUTE(A1," ",?,LEN(A1)-LEN(SUBSTITUTE(A1," ",)))))
which uses a trick of using the ? as a temporary substitute. Actually, this leaves a trailing space. So use this instead:
  =LEFT(E4,FIND(?,SUBSTITUTE(E4," ",?,LEN(E4)-LEN(SUBSTITUTE(E4," ",))))-1)
to rid of the final space (which you won't be able to see but which can mess you up if you try to pile these results on top of each other.)

If you want everything but the last two of several space-separated entries:

=LEFT(A1,FIND(?,SUBSTITUTE(A1," ",?,LEN(A1)-LEN(SUBSTITUTE(A1," ",))-1)))

Unhide top row

1. Press F5. Excel displays the Go To dialog box. (Click here to see a related figure.)
2. In the Reference field at the bottom of the dialog box, enter the number of the row range that you want to unhide. For instance, if you want to unhide rows 2 through 3, enter 2:3. Likewise, if you want to unhide row 1, enter 1:1.
3. Click on OK. The rows you specified are now selected, even though you cannot see it on the screen.
4. Choose Row from the Format menu, then choose Unhide.  In 2007, Home/Format/Hide & Unhide/Unhide Rows

Zeros, leading: make sure they stay there – Somehow you get in the situation where you’ve stored text info with leading zeros – like 5-digit zip codes – as numbers so you lose all your leading zeros.  Now, of course, you can make them look like they’re there by Format Cells / number / and then either Special/Zip Code or Custom / 00000.  But if you want to do a mail merge with this data that won’t help a bit.  No, assuming you have a whole column (J) of 500 rows of these wrongly stored zip codes, one way to do this is to create two adjacent columns.  In the first column, ="0" &J1.  Drag that formula down to all the cells in that column.  This is pretty simplistic, assuming you have only 4-digit zip codes.  If you have a mixture of 4 & 5 digit zip codes, then you have to do conditional formatting: =IF(LEN(J1) = 4,"0" &J1, J1).  Or, programmatically for rows 1 through 500:

For i = 1 To 500
    If Len(Range("J" & i)) = 4 Then
        Range("J" & i) = "'0" & Range("J" & i)
    End If
Next i

Then highlight the whole 2^nd column, copy, and then “paste special” into the 3^rd column, taking only values.
