Key Concepts
- Pivot Tables and Sort/Filter
- Conditional Formatting
- Charts
- Concatenate and Indirect
- TEXT functions
- Goal
Pivot Table
Data Summarization Tool. ALT N V
- Efficient in making calculations by group
- Useful for segmented data. Ex. Car Sales by Month, Year, Region, Make, Model.
- Must refresh to update if source data changes
Sort and Filter
- Once formatted as table can use dropdown menu on column headers
- ALT H T to format as table (ALT JT G to return table to range)
Conditional Formatting
Useful tool to apply formatting based on preset rules (or any formula you input) ALT H L to access menu
- Common uses
- Highlight cells that are greater/less than a value
- Display icons based on cell values
Using Charts
Used for visual representation of data.
- Scatter is almost always preferred to a line chart
- Use a combo if graphing more than one series and scales are different
- Always label graph properly
- Should be clear to reader what graph is depicting
Concatenate and INDIRECT
- Can use the CONCATENATE function or the & symbol to "glue" text or references together
- Per usual text inputs require ""
- INDIRECT is used to grab a cell reference when the input is text based.
TEXT functions
Useful functions to manipulate text strings
- =LEN(text): returns length of referenced text string
- =LEFT(text,num_chars): returns the specified number of characters (num_chars) from the left of beginning of text string specified by text.
- =RIGHT(text,num_chars):returns the specified number of characters (num_chars) from the end of text string specified by text.
- =MID(text,start_num,num_chars): returns the text beginning at the n'th character(start_num) and ending n characters later (num_chars) given the text string specified by text.
TEXT functions Cont'd
- PROPER(text): Capitalizes the first character of each word and lower case for all other characters.
- UPPER(text): Changes all characters to upper case.
- LOWER(text): Changes all characters to lower case.
- SEARCH(find_text,within_text,[start_num]):Searches the specified text string (within_text) for the text (find_text) and returns the location where that text begins. Optional command start_num tells Excel to start searching for that text in the text string beginning n characters into the string. Allows wildcard characters and case insensitive.
TEXT functions Cont'd
- FIND(find_text,within_text,[start_num]): Exact same as SEARCH but does not allow wildcard characters and is case-sensitive.
- SUBSTITUTE(text,old_text,new_text): Replaces old_text with new_text in given text string.
- REPLACE(old_text,start_num,num_chars,new_text): Given a text string (old_text) replaces the specified number of characters beginning at a given position(start_num) with new_text.
- Text-to-column (ALT A E): Given a column of data will split each text string into multiple columns based on specified delimiter or fixed width.
Goal Seek
Very useful Excel feature to solve an equation for a specified value by changing an input. ALT A W G
- Set Cell: Cell that contains a formula function that you want to set to a certain value
- To value: Value you want set cell to change to
- By changing cell: this cell must be referenced in the set cell formula.
