Starting October with a hint for Microsoft Office, Excel.
Excel is the spreadsheet calculation package Microsoft Office, Considered the best there is in the market by many specialists in the subject. I personally do not use, and when I need to use a spreadsheet opt to at Google Docs, always free and functional. But there are situations in the office, day-to-day work that you can not access the Internet and the way is to turn it with Excel.
Today a co-worker asked me how could I identify and remove duplicate records in Microsoft Excel. Of course it was a short list, you could even look at her and put an X in the column that represents the duplicate filter and then to remove, but we are talking here of a list of more than ten thousand records.
How to Identify and Remove Duplicate Records in Excel

Let’s use the function COUNTIF.
Imagine we have a list of names with cell phones and want to know who has two phones.
In column C, put the formula = COUNTIF (A2: A6, A2)> 1
we count the cell A2 to A6, differing only by A2, who has more than one returns True (true).
Copy to the end of the list (or drag down to cell C2) to process all records.

Once you do a column C will have only true or false (true or false), and you can use the filter to display only those with true value, which represents people who have a listing in our two cell phone numbers.
This same reasoning with the COUNTIF function can be used for other values and records, simply expand the selection of records.
