would take to create a structured list of data from a text file that contains values stored on separate lines First determine the format you need so you can find the best way to change the unstructured data into structured data Then copy the data from the text file and paste it into a new workbook Then change the data into comma separated values Then use a text function to link together or concatenate the information from multiple cells into one 2 Why should you remove unnecessary spaces from data imported from another source Ho do you remove unnecessary spaces from a text string Because sometimes there are blank spaces at the end of texts You can remove these blank spaces from a text string by using the TRIM function 3 How do the FIND and SEARCH functions work and how are they different The FIND and SEARCH functions return the starting position of one text value within another The difference is that the FIND function is case sensitive and the SEARCH function is not 4 What options are available for parsing data when you use the convert Text to Columns Wizard First way is to identify the character that separates the data The second way is to set field widths to identify the breaks between data that appears in columns 5 What are the advantages and disadvantages of using the Subtotal tool to analyze data The advantages are that it creates summary reports that quickly organize data into categories with subtotal calculations and lets you collage and expand the level of detail in the report A disadvantage of the subtotal command is that it works only with one category and one subtotal calculation at a time 6 What is the difference between an unstructured list and an Excel list The difference between an unstructured list and an Excel list is that because all the data in an excel list are in a structured format one can use the filter feature to sort through the data using different methods 7 List and describe the six available options when using the AutoFilter feature in an Excel table Sort A to Z Sort Z to A Sort by Color if cells are manually or conditionally changed to have background color it filters these colors Clear Filter From removes any filters and restores original data Text Filters filters alphanumeric text by specific characters Number Filters Date Filters filters by date and time values Custom 8 What is the primary advantage of storing data in a database and importing that data into Excel It ensures that your data is secured and protected but can be analyzed using a spreadsheet easily thus reducing redundancy 9 Explain the steps you must take to import data stored in an Access database into Excel Open a workbook where you want to import the database data Select the first blank cell and then click the From Access button in the Get External Data group on the Data tab on the ribbon In the dialog box find the file select it and click to open it 10 What is the Query Wizard and when do you use it The query wizard lets you choose your data source and select the database table and fields you want to import into a workbook It prompts you to define any criteria for the data by
