I need to count the number of observations in these three files. Is it possible to count the number of obs without importing it in SAS? Also, if we really need to import the file then how can we import these three files together.
In the file name and is the year name; 01,12 and 11 are the month names and 31 and 30 are the month end dates. So I think you will have to import them if you want to do this in SAS.
There's really no faster way; you of course could write a macro and execute that three times, and have it calculate your names given month dates etc. Learn more.

Feedback on Q2 Community Roadmap.There's no faster method for generating SAS code that reads your data exactly the way you need it. I use the tool so often that I take for granted some of its neatest features, and I forget that many new users and even veteran users might not know about them. In this article, I'll review a few of the cool things that this task can do for you.
Update 23Mar I've recorded a video that shows how to use the Import Data task as a start, and then adapt the code that it generates for reuse in other environments, with other files, and to read multiple text files in a single step. Watch the video to learn moreor scroll down to read my step-by-step tips. We think of CSV files and Excel files as the main standard for data exchange among systems, but many legacy systems still produce and consume fixed-width text data formats.
The "Fixed columns" option on the Import Data task can make this job simple. You can use the Import Data wizard to define the boundaries of your columns by adding boundary lines with just click-and-drag operations. When you select "Fixed columns" as the input text format, you'll see a layout ruler that looks like this:.
Click at the column boundaries referring to your original spec! Then click Next, and fill out details for the column names and types:. Here's a click-saving trick.
Sometimes you have an input data file that contains many columns that share the same properties: type, length, and SAS format. It can be tedious to click and modify the properties of each column that you want to import. There's a shortcut on the Define Field Attributes page of the wizard that you can use to change the attributes for several columns at the same time.
The "Field Attributes for Multiple Selections" window appears, and you can change the necessary attributes just once and apply to the many items you picked.
In a previous article I described how the Import Data task works "behind the scenes. However, with a couple of tweaks you can coerce the Import Data task into creating SAS code that you can almost just "lift and shift," as is. The first option is hidden under the Performance window, labeled as "Bypass the data cleansing process. While doing no harm, most of the time this step isn't needed -- especially if your original data file is well formed.
And since this step changes the input file, it's isn't repeatable outside of this task. My first tip for the best reusable code: click PerformanceThere are quite a few methods that people have come up with to import all of the sheets from an Excel workbook into SAS at once. Some are quite long and confusing.
In this post, I will go over one of the simpler methods I found online. I will also go over the problems I had while running it, and how I solved them. So first you need to set up your Excel spreadsheet as a library, using a libname statement. I ran into my first problem here. You can read more about installing and using the PC files server here. But anyway, here is the first part of the code I ran:. You can read more about it here. For example, I took this opportunity to rename some variables that were in all of my sheets.
Once I renamed my sheets using this VBA codeeverything worked for me.
I love data. Using data for good, to have a positive social impact is important to me. I am particularly interested in using data to improve healthcare and international development. I have formal training in epidemiology and applied biostatistics as well as 3 years of experience using SAS and SQL for data management and analysis in international research studies. I'm always working to learn new things and become a better analyst.
In addition to my day job, I'm also learning Python, analyzing data from a mobile healthcare app, and blogging about SAS. View all posts by Sarah Ramteke. You are commenting using your WordPress.

He has over 8 years of experience in data science. During his tenure, he has worked with global clients in various domains like Banking, Insurance, Telecom and Human Resource. Followed as suggested above but did not get my files imported. The result of the operations have been set to a missing value. Thank you for letting me know the issue.
I have fixed the code. It is working fine now! How can we use the code when some variables may be different or some files have some variables that others don't have. Can you update the code to only include the first 5 observations first 5 files in the folder and start with the second line of the excel files? Thanks for providing this useful guide on importing excel files. It's really very useful. Also, I added your blog to my favourite sites list.
Keep sharing. In one of the interview, i was faced the below question, plz help and give me the code: example :in daily reports- if we have three excel files, in each excel - today data is available in two sheetstomorrow data may available in three sheets. The code successfully imports all 13 Excel files but doesn't generate a data set of the all the observations.
The output file reflects only the observations in the last imported file. Please advise. About Author: Deepanshu founded ListenData with a simple objective - Make analytics easy to understand and follow. Unknown 2 January at Deepanshu Bhalla 3 January at Anonymous 28 May at Anonymous 26 August at Unknown 20 November at Our tutorials reference a dataset called "sample" in many examples.
If you'd like to download the sample dataset to work through the examples, choose one of the files below:. We have updated the tutorial to include directions for both versions of SAS.
This first screen will ask you to choose the type of data you wish to import. Click Standard data source and then choose the program that is the source of your data from the drop down menu.

The second option, specifying a file format, is not covered in this tutorial. In our case, the dataset we want to import is an Excel file, so select Microsoft Excel Workbook. As you can see, SAS provides you with a large variety of data types to import.
Now you need to tell SAS where to find the file you want to import. You can either type the file directory into the text box, or click Browse and choose the file to import. SAS then asks you what sheet from the file you want to import. In this example we will choose Sheet 1 since our data appears on Sheet 1 in the Excel file. Then click Options. Be sure and select the options that are correct for your dataset. The default is for all options to be checked, and that works for our purposes.
Click Next. This next step tells SAS where you want to store the newly imported dataset. The first drop-down menu is a list of available libraries that you can choose to store your newly imported SAS dataset in. If you want it to be temporarily stored for now, choose WORK. The next dropdown menu, under Memberrequires you to name the dataset. You can type in a dataset name here, or choose a dataset from the list. NOTE: Choosing an existing dataset from the list will over-write that data; the existing file in the library will be replaced with the file you are importing.
Then, click Next. The last step allows you to save the statements that SAS generates while executing the Import Wizard into an Editor file.
This is recommended. This way you have the import steps saved, and you can go back and re-run it or modify it later if you need to. You can type the file directory directly into the text box, or click on Browse to locate a folder to save the program in. The last step is to click Finish. Clicking on the finish button was probably anticlimactic, because nothing seems to happen.
No data appears for you to see and enjoy; no Editor file appears for you to manipulate and play with. Remember the earlier tip to look at your Log window after you execute any statements in SAS. The Log window provides this Note statement that tells you your dataset was successfully created.In this article, I introduce some methods to quickly batch import them.

To import all the csv files form a folder into a single sheet, you can use below VBA code. VBA: Import csv files from a folder into one worksheet. Press F5 key or click Run button to execute the VBA, and a dialog pops out to select a folder that you want to import all csv files from. Click OKand a dialog pops out to remind you if clear the contents of active worksheet before importing, here I click Yes.
After clicking Yesall csv files in the selected folder are imported into the current sheet, and place data from Column A to right. Tip: If you want to place csv files horizontally in a worksheet, you can use below VBA.
Click Run button or F5 key to run the VBA, and select a folder in the popping dialog, see screenshot:. With its powerful Combine utility, you can quickly combine multiple xml files or csv files into one workbook or one Excel sheet. And in the step 1 of Combine dialog, choose one separation option as you need. Click Next to go to step 2 of the Combineclick Add to add files from various folders or files from one folder to Workbook list, and also you can specify the sheets you want to combine from Worksheet list of right section.
Click Next to the last one step of Combineand you can specify the options.

Click Finisha dialog pops out to remind you select a location to save the new combined result.Me, the newbe, has created a macro to read in some csv files. It works but I think the code can be smarter since now I do this manually for something like 30 files which are all located in the same folder. Here an example for reading in 5 files. My is, can I make this code less manually intensive?
There are more files coming in. Can I import the whole folder in one time instead of typing them out? View solution in original post. Its a good idea to do a search before posting a question.
There are literaly hundreds of posts on this topic:.
Note that proc import guesses types so as the number of files gets larger it's more likely that you'll get inconsistent data types, ie a VAR is char in one dataset and numeric in another. I'm not understanding your question. I would suggest starting your own thread and explaining in detail. It's sometimes better to tell us what you have and what you need - and only then tell us what you've already tried. You've got a lot of experienced people in this forum and it's sometimes worth to give the big picture as then you might get solution approaches you haven't even thought about.
