Data in a two column database (A3:B13) can be Auto filtered on column A with one or many conditions.  Data in column B will be numbers only (positive, negative or 0's) - no text values.

After filtering data in column A, one may want to extract the unique numbers from column B to cell A18 (and then downwards).  Data from cell A18 downwards should keep changing with different filter conditions specified in the Auto filter drop down of column A.

You may refer to my solution in the this workbook.

To extract unique values from an unfiltered range without any conditions, you may refer to the following link

To extract unique values from an unfiltered range with multiple conditions, you may refer to the following link

Assume the following sentences in range B2:B6

B2 - This is an Apple Pie
B3 - An apple a day keeps a doctor away
B4 - These Pears, apples and mangoes are sweet
B5 - In this season, prices of mangoes have increased
B6 - This is a glass of Guava juice

In range B9:B10, type Mango and Apple.  The objective is to count the sentences in range B2:B6 which exclude the words mentioned in range B9:B10.

The array formula (Ctrl+Shift+Enter) for getting the count of exclusions would be:

=SUMPRODUCT(1*(MMULT(TRANSPOSE(1*(ISTEXT(\$B\$9:\$B\$10))),1*(ISERROR(SEARCH(\$B\$9:\$B\$10,TRANSPOSE(\$B2:\$B\$6)))))=COUNTA(\$B\$9:\$B\$10)))

The result should be 1.

The array formula (Ctrl+Shift+Enter) for getting the count of inclusions (sentences which include these words), would be:

=COUNTA(\$B\$2:\$B\$6)-SUMPRODUCT(1*(MMULT(TRANSPOSE(1*(ISTEXT(\$B\$9:\$B\$10))),1*(ISERROR(SEARCH(\$B\$9:\$B\$10,TRANSPOSE(\$B2:\$B\$6)))))=COUNTA(\$B\$9:\$B\$10)))

The result should be 4.

One can also solve the problem with the PowerPivot tool.  You may refer to my PowerPivot solution in this workbook.

Assume there are multiple files saved in a specific folder.  There can be Excel, Word, PDF, PowerPoint and other files types saved in this folder.  Furthermore, Excel files can have following extensions - .xls,.xlsx.xlsm.  Each Excel file has multiple worksheets with one worksheet being named Sheet1.  While data on sheet1 of all Excel files will start from cell B3 (first header cell), there can be a variable number of rows and columns from cell B3 onwards.

The task is to consolidate data from sheet1 of all Excel files to multiple worksheets of one Excel file.

The Question and Instructions have been clearly explained in the "Question and Instructions" worksheets of this file.

To see the solution work,

1. Save the following zipped folder on our desktop.  Unzip the folder and place Data Files folder (with all its files) on your desktop; and
2. Change the path in cell B2 of worksheet "Query and file listing" of Destination.xlsx file to the path of your folder saved in step 1 above.
3. Click on the blue button on worksheet "Query and file listing" of Destination.xlsx file.

Assume a folder named Test on the desktop.  In this Test folder, there is another folder named Survey reports.  In the Survey reports folder, there are Word documents, PowerPoint files, Excel files, PDF files and all sort of other files types.

In a new workbook, one may want to list down all Excel files from the Survey reports folder (saved on the desktop) without using VBA.  Furthermore, for new Excel files added to the folder, the list should keep updating.

Solution for MS Excel 2010 and higher versions

If you are using the Power Query add-in, then a few simple steps (no formulas at all) can solve this problem.  The result will be dynamic and refreshable (just as in a Pivot Table).  In Power Query, there is a feature to append data from multiple workbooks into one running range.  The detailed process to do so is described below:

1. Go to Power Query > From File > From Folder
2. Choose the Test folder on the desktop and click on OK
3. Filter the extension column on "Contains" .xls
4. Right click on the Name column heading and choose "Remove Other columns"
5. Click on Apply and Close

This should now list down all MS Excel files lying the Test folder.  This is a dynamic list i.e. add or remove Excel files from the folder and just right click on any cell and select Refresh.

Solution for all versions of MS Excel

Try the following procedure to get a list of all Excel files from the folder:

1. In the new workbook, press Ctrl+F3 > New.  In the name box, type FL
2. In the Refer to box, enter =FILES("C:\Users\Ashish\Desktop\Test\Survey Reports\*.xls")&T(NOW()).
3. Click on OK and Close

In cell A3 of sheet1, enter the following formula and copy down

=IF(ISERROR(INDEX(FL,ROW()-2)),"",INDEX(FL,ROW()-2))

If you add another Excel file to the Survey report folder, just press F9 anywhere on sheet1 and the file will appear in the list.

Change C:\Users\Ashish\Desktop\Test\Survey Reports\ to your actual path from where you want to extract the Excel files.

To generate a list of all tab names from in an Excel file, you may refer to the following post.

In range G13:G17, assume the following entries - VG:25, NS:50, NS:20, #DIV/0! and VG:150.  To sum up the values where VG appears, you may refer to my solution in this workbook.

Given an alphanumeric string, one may want to perform the following

Extract phone number from the string

Assume a list of customer addresses with multiple phones numbers mentioned in the address field itself.  These numbers may be mobile numbers and/or mobile numbers.  Furthermore, PIN codes may also be mentioned in the address string.

One may want to extract only the phone numbers to another column.

You may refer to the my solution in this workbook.

Extract one specific 20 digit number from the string

Assume cell descriptions which contains two 20 digit numbers occurring anywhere in the string.  Once may want to extract only that 20 digit number which has the word New before it.

A user inputs raw material purchase data in a master sheet.  This data is entered by date and vendor.  One may want to view individual vendor sheets at a monthly level.  In the attached file, i have presented two solutions - a macro based one and a formula based one.

The data layout and instructions are very clearly mentioned in the this workbook.

You may also refer to the a similar article at the following link.

In a multi column database, assume a filter has been applied on some columns.  Post filtering, some error values (such as #DIV/0!, #NA etc.) appear in the one of the numeric columns.   The objective is to sum numbers in a numeric column.  The usual SUM() function would not work because the range of sum function should be error free.  Furthmore, the SUM() function would also include the invisible rows of a filtered range.  The SUBTOTAL(9,range) function would not work either because the range in the SUBOTAL() function should also be error free.

Assume that the database is in range A11:B20.  Column A has been filtered and column B is the column of numbers which also has the error values.

For Excel 2007 and prior versions, the following array formula (confirmed by Ctrl+Shift+Enter) will sum the visible rows a filtered range ignoring error values.

=SUM(IF(NOT(ISERROR(SUBTOTAL(109,OFFSET(B10,ROW(B11:B20)-ROW(B10),)))),SUBTOTAL(109,OFFSET(B10,ROW(B11:B20)-ROW(B10),))))

For Excel 2010 and higher versions, the following formula will work

=AGGREGATE(9,7,B11:B20)

Create a data validation list from a range which has data appearing in multiple rows.   I have shown two cases - one using macros and other using formulas.
