structured list of data from a text file that contains values stored on separate lines Determine format needed most likely Comma separated values CSV Copy data from file and paste into workbook In the column next to the data use CONCATENATE A1 A2 A3 A4 A5 A6 to merge data into one cell By inserting the data in the CONCATENATE function will be separated by commas In an adjacent cell use the RIGHT function to sort through the data to sort the data using a common text In this case the data would be sorted out by a dash followed by the last four numbers of the phone number The function would look as follows RIGHT cell selected 5 To ensure the right function returns the values desired next a TRIM function into the concatenate function in order to remove unnecessary spaces in each value CONCATENATE TRIM A1 TRIM A2 TRIM A3 Use the FIND function in order to sort through the data The function FIND cell selected will search through the columns with the RIGHT functions and return a value of 1 if the first letter of the text in that cell is a dash Otherwise if the first letter of that text is not a dash it will return VALUE Select all data and copy and paste values only onto a new worksheet to avoid potential problems with the functions updating Once again select all data and click the sort and filter button on the ribbon on the home tab In the sort dialog box sort the values by column D in ascending order which would place the values of 1 at the top of the data Delete all other data except the data in column B that has a value of 1 in its corresponding D column cell 2 Why should you remove unnecessary spaces from data imported from another source How do you remove unnecessary spaces from a text string It may cause errors in Excel the trim function 3 How do the FIND and SEARCH functions work and how are they different The FIND function returns the starting position of one text value within another text value It is also case sensitive The SEARCH function does the same thing as find however it is not case sensitive 4 What options are available for parsing data when you use the Convert Text to Columns Wizard There are 2 ways to parse divide the data when using the wizard The first way is to identify the character that separates the data In comma delimited files commas separate the data also another common way to separate data is through spaces made using the tab key The second way is to set field widths to identify the breaks between data that appears in columns For example if the first field uses the character 1 10 and the second field 11 15 you set a column break between 10 and 11 and another break between 15 and 16 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 …
