Feature on Excel 2007/2010 to Remove Duplicates

Maybe you faced this situation: you have a lot of rows in Excel with many columns and you that you are only looking for codes which are in the first column to build a useful report.

As you are very intelligent, you decide to copy the first column on another sheet to begin the construction of your desired report. However, you realize at that moment that you have indeed duplicated codes, one code you saw it on row 13 and the same on row 65 and so on.

Now, you have to look for a way to do it without wasting your time, therefore I will give a idea that have just came to mi mind:

1) Copy the column in a new sheet and apply an ascending order.

List with duplicates

2) Use the equal operator to determine if the number on the left is equal to its predecessor. At this point you will have a TRUE or FALSE in the right cell of each number.

Compare the cell with the cell above

3) Filter the TRUE cells and remove these rows, you will keep only FALSE cells and, as you can see, there will be no duplicate codes.
 
Delete all the cell with the TRUE value

But, as you are using Excel 2007/2010... why don't you use the remove duplicates button? haha. For this just select the cells you want to be with no duplicate values, go to the Data ribbon and click the "Remove duplicates" and wait until Excel do its job.

I Need to Send an Automatic Email with Lotus Notes

Image
If you don't know, Lotus Notes is an email client used in a lot of companies around the world. Therefore, I use it at work everyday, but someday I needed to send an automatic email to a few people all Fridays at 10:00.   To get this task accomplished I decided to create an agent and avoid remembering the fact of sending the email. As you can image, I did this example on a Spanish version of Lotus Notes 8.5 but I will explain it clearly enough. The first step is getting yourself into the inbox, then select the "Create" menu item and inside of it, click on "Agent...". You will get a dialog box opened, in this we have the possibility of setting the rules for this agent. However, in this case we will only set "Trigger" option to "On schedule" with the "Weekly" frequency. Don't forget to push the "Schedule..." button to program the agent in the right way. After this, select "OK" and close the dialog bo

Inserting Rows o Columns in Excel Not Permitted

Image
I'm opening an Excel file and when I try to insert a new row or column I get a message error giving me a large text about how this is not possible. I have seen many people facing this message, although this gives the solution, sometimes it's hard to understand what this message is trying to say.     But, what's happening? Let me tell you that you' re using all the rows or columns of the file, yes, believe it or not you are having information (even blank space) at least at the last row or column allowed. So, when you want to add a new one, Excel tries to delete this row or column because it will be out of range with the new element inserted. The solution is going to the last column or row, to do so you can use this shortcut: Ctrl + Down arrow if you want to go to the last row or Ctrl + Right arrow to go to the last column, as shown in the images.         Then, you just have to select the entire row or column and delete, the next step is to save the file to t

Turn Horizontal Visio Swimlanes into Vertical Ones

Image
In one ocassion, a friend at work called me because she had a problem with Microsoft Visio , she was trying to draw a process flowchat but using swimlanes, this was not a problem until she realized that it would be better to use vertical swimlanes instead of horizontal ones.    But, when she tried to drag a vertical one it just put together to the previous swimlanes created before.  To avoid creating a new visio document and lost your work just go to 'Cross-Functional Flowchart' ribbon and select 'Orientation' and 'Vertical'.     And it's done, now you can work with vertical swimlanes or if you like it you can turn them back to horizontal ones.
