Using Spreadsheets
Spreadsheets do very little that you could not do
manually, with a calculator, or in a word processor.

However, they do it a lot more quickly, and with a
whole lot less effort.

• Sorting data • Comparing data
• Filtering data • Rearranging data
• Deriving info • Collating data
(Finding maximums, minimums, averages, etc.)

Using Spreadsheets
This presentation is designed to:
• Go over universal terms & concepts.
• Give general step-by step instructions on how
to perform various tasks.
• Introduce project ideas that can be used in
your library.

Instructions for different programs are available
online – if yours isn‟t listed, just ask!

Programs & file types
There are many spreadsheet formats/programs
in existence.
MS Excel (.xls / .xlsx) Google Spreadsheet
Open Office Calc (.ods) MS Works Spreadsheet (.wks/.xlr)
Etc.

These are the only formats which will allow you
to retain your formulas. Everything else will
only save the results of the formulas.

There are some formats which can be smoothly
imported to / exported from spreadsheets.
• Comma Separated Values (.csv) [also known as
“comma delimited”]

• Tab Delimited Text (.txt) [also sometimes called
Tab Separated Values, and saved as .tsv]

To import/export you will need to do one of these:
• Open / Open as.. / Convert to.. / Import
• Save as / Export to

There are also data sources which often interact
with spreadsheets, but don’t do so smoothly.

• HTML: copy & paste tables to (not from) spreadsheets,
and use spreadsheets to create HTML code.
• Word processors : best done through c&p of tables
• Non-delimited/separated text files: needs functions to
parse text

Freezing rows & columns
Spreadsheets let you “freeze” rows (at the left),
and columns (at the top), so they always show.
• Useful when working with too much data for 1 screen

versus

Freezing rows & columns
INSTRUCTIONS
1. Go to the cell below & to the right of all the
rows & columns you want “frozen”.
2. Follow the instructions for your program below.
Excel 97: “Window” menu, “Freeze” (Alt-w-f)
Excel 2007: “View” tab, “Freeze Panes” submenu
OpenOffice: “Window” menu, “Freeze” (Alt-w-f)
Google Docs: “View” menu, “Freeze rows” or
“Freeze columns”

Special Pastes
As values Most spreadsheets have a separate
As Text menu for “special” pasting options.
Transpose • Some options are very helpful in
multiple contexts.
• Context-sensitive menus might offer
different options depending on clipboard
contents or other factors.

Special Pastes: As Values
As Values Pasting “As Values” means just the
As Text results of the formulas
Transpose • Formulas are not pasted.
• Formatting is not pasted.
• Available when pasting from & to a
spreadsheet.
• Has (mostly) the same effect as pasting
to a word processor, & then back again.

Special Pastes: Transpose
As Values Pasting “Transpose” switches the
As Text columns and rows.
Transpose • Cell A1, B2, C3, etc. stay put.
• Cell B1 (2nd column, 1st row) moves to
cell A2 (1st column, 2nd row).

This option may not appear in a converted
.csv or .txt file. If so, just “save as” a
spreadsheet, close, and re-open.

Rearranging
Rearrange You might want to re-arrange data to:
Collate • Make it more readable
Sort
• Make it more understandable
Filter
Compare • Make it easier to manipulate
Derive info

Rearranging: Transposing
Rearrange Transposing is one type of re-arranging.
Collate
Sort
It‟s most useful when:
Filter • There are few rows, and many columns
Compare
Derive info • Column headers are wider than row
headers.

Rearrange Example: 2 pieces of data about all 100
Collate counties in NC
Sort You can read it this way:
Filter
Compare
Derive info
• columns are too narrow to read headers
• Less than 1/10th of 100 counties are
visible at any given time


Sort Or you can read it this way:
Filter
Compare
Derive info
• columns are wide enough to headers
• Only 1/50th of 100 counties are visible
at any given time

Rearranging: Switching
Rearrange Switching the order of columns or rows
Collate is another type of re-arranging.
Sort
Filter It‟s most useful when:
Compare • There are natural sub-groups that are
Derive info best viewed together
• You‟re comparing the data in two
widely separated columns

Rearrange Example: Many pieces of data about all
Collate 100 counties in NC
Sort Because EDIS lists the counties in
Filter alphabetical order, industrial counties
Compare
might be next to rural counties.
Derive info
Example: Wake ($72k average) & Warren ($36k)


Sort Switching column/row order lets you
Filter group them by region, such as in this
Compare
example, where the “Eastern” counties
Derive info
have been grouped together.

Rearrange INSTRUCTIONS
Collate 1. Insert a column where you want the
Sort column moved to.

Collating data
Rearrange Collate means “put together in order”.
Collate
• Two kinds that are easier in spreadsheets
Sort
Filter – Combining data from a single source
Compare
– Combining data from multiple sources
Derive info
• Note: A “source” is a single file, or a
single copy/paste.

Collating data: single source
Rearrange Example: Author names
Collate
Imagine that you have a list of authors,
Sort
Filter
and want to search for them in a database.
Compare • The names are in two columns: one for
Derive info first name, and one for last.
• The database needs them as “last, first”.

Rearrange Solution: Author names
Collate 1. Go to any blank column.
Sort
2. Use the concatenate function to
Filter
combine the two cells on the same row.
Compare
Derive info 3. Extend/fill/paste the formula down for
the rest of the list.

Rearrange More on concatenate
Collate
• Concatenate just puts together whatever
Sort
Filter
you tell it to, as text, like a toy train.
Compare • In this it puts together B2‟s value, then a
Derive info comma & space, then A2‟s value.

Collate • You can print, but not export.
Sort
• Available data is split among 5 “views”
Filter
Compare • Many lists have more than 1 page.
Derive info

Original data source: https://www.morningstar.com, “Terrific 10-Year Records” screen

Rearrange Solution: Morningstar (part 1 of 4)
Collate • Spreadsheet (SS): Insert worksheets
Sort until you have a total of 7 (one per view,
Filter plus 2).
Compare
Derive info
• Site: Highlight & copy the entire page
for the first view. (Ctrl-A, Ctrl-C.)
• SS: Paste as text in sheet1.
• Repeat previous 2 steps for remaining
views, pasting in sheet2 through sheet5.

Collate • SS: In sheet 6, create simple formulas to
Sort pull the data from the other sheets.
Filter
• Note: It may be best to type the headers.
Compare
Derive info

Collate • SS: Copy the contents of Sheet6.
Sort
• SS: Paste as values into Sheet7.
Filter
Compare • Note: The cells look the same, but the
Derive info formula bar in Sheet7 will have the
value, not the reference.

Collate • If there is more than one page per view,
Sort repeat parts 1 & 3, EXCEPT that you
Filter should paste the values in Sheet7
Compare
immediately below the previously
Derive info
existing values.
• When pasting a second set of values you
do not need to re-copy the headers.

Rearrange Many databases allow you to sort.
Collate However, spreadsheets let you:
Sort
Filter
• sort column order, instead of row order.
Compare • sort using multiple criteria.
Derive info
• save multiple sort orders.
• sort by more than numbers & letters.

Sorting data: Column order
Sort • You can manually shift 90+ counties
Filter into their categories, OR…
Compare

• You can insert a row, enter the region
names, and then transpose, sort by
region name, & transpose back.
Note: Some spreadsheets allow you to sort
column orders without transposing.

Collate Imagine you‟re helping a house-hunter.
Sort
• They want to focus on houses that are
Filter
priced within 10% of their assessed

Derive info
value.
• If a house is in that category, they want
it ranked by square footage, not by the
percentage.

Collate Solution: Use a sort column with an “if”.
Sort
Filter
• General syntax: if(condition,then,else)
Compare • In other words, if “condition” is true,
Derive info “then” show X, “else” show Y.
Note: Some spreadsheets allow you to sort
by formatting, which can also work when
combined with conditional formatting.

Collate Solution step-by-step:
Sort
• Insert two columns, called “percentage”
Filter
and “sort”.
Compare
Derive info • In percentage: =abs(price-value)/value
• In sort: =if(percentage<=.1,sqft, “zz”)

Rearrange There are many functions which allow
Collate you to compare one piece of data to
Sort another.
Filter
• if
Compare
Derive info
• countif (not count!)
• match
• find
• isnumber

Rearrange Syntax:
Collate • if (condition,“is match”,“not match”)
Sort
Filter
Behavior:
Compare • Returns “is match” if condition is true.
Derive info • Returns “not match” if false
Example:
• =if(a1=“y”, “is y”, “is not y”)
• If a1=“x” then it will return “is not y”.

Rearrange Syntax:
Collate • countif (range, testvalue)
Sort
Filter
Behavior:
Compare • Returns the # of cells in the range that
Derive info equal the testvalue.
Example:
• If a1=“a”, a2=“b”, a3=“c” etc. then
countif(a1:a26,“b”) would return 1.

Rearrange Syntax:
Collate • match(testvalue, range,0)
Sort
Filter
Behavior:
Compare • Returns the location of the first cell
Derive info matching testvalue within the range.
• Returns an error if no cell matches.
Example:
• If a1=2,a2=4,a3=6, etc, then match(“6”,
a1:a9,0) would return “3”.

Rearrange Syntax:
Collate • find(testvalue, cell)
Sort
Filter
Behavior:
Compare • Returns the location of the first
Derive info
occurrence of testvalue in the cell.
• Returns an error if it doesn‟t occur.
Example:
• If a1=“book” then =find(“k”,a1) would
return “4”

Rearrange Syntax:
Collate • isnumber(cell)
Sort
Filter
Behavior:
Compare • Returns true if cell contains a number,
Derive info and false if it doesn‟t
Example:
• isnumber(“a”) returns false.
• isnumber(1) returns true.

Comparing data: Function example
Collate Even within a single platform there might
Sort be thousands of journals.
Filter
Compare • Checking them all by hand is slooow.
Derive info • Data can be checked quickly against list
from host, if it‟s in the same order.
• Variant titles can cause lists to be in
different orders.

Collate Solution (step 1 of 5)
Sort
1. Insert 3 columns between the data
Filter
sets, label 1st “sort1”, and 3rd “sort2”.
Compare
Derive info Explanation:
– 1st column will hold the “sort” for 1st data set.
– 3rd column will hold the “sort” for 2nd data set.
– 2nd column will stay blank, so the sets can be
sorted independently.

Collate Solution (step 2 of 5):
Sort
2. In “sort1”: =if(isnumber(match(titles1,
Filter
titles2)), “match”, “zz”)
Compare
Derive info Explanation for match(titles1,titles2):
• This takes the value in titles1 that‟s on the
same row as the formula, and looks for it in
titles2. It returns a number if it finds a match,
and an error if not.

Sort
Filter
Compare
Derive info Explanation for isnumber(match()) :
• This returns true if match returned a number,
and false if match returned an error.

Sort
Filter
Compare
Derive info Explanation for if(is#(), “match”, “zz”):
• If isnumber returned true, this returns “match”
• If isnumber returned false, this returns “zz”

Sort
Filter
Compare
Derive info Result:
• The 1st data set can now be sorted so that all
the titles with matches go to the top, and the
ones without go to the bottom.

Sort
Filter
Compare
Derive info Explanation/Result:
• Same as Step 2, except it‟s checking for the
title from titles2 in the range titles1.

Sort
4. Sort the data sets, with “sort” first and
Filter
the title column second
Compare
Derive info Explanation/Result:
• The matching journal titles in the two data sets
should now be lined up with each other.
• The shorter list of non-matching titles is easier
to check for common (fixable) variants.

Sort
5. In the middle blank column, enter an
Filter
“if” checking whatever you want.
Compare
Derive info Example: if(url1=url2,“good”,“check”)
Explanation/Result :
• All journals with correct URLs labeled “good”.
• If all journals are “good”, you‟re done!
• If not, you still have a fewer to check by hand!

Rearrange Deriving information is done using
Collate formulas and functions.
Sort In general, functions are what you do…
Filter • Add up cash on hand for parking /lunch
Compare
• Calculate a waiter‟s tip
Derive info • Figure out how much time is left
…and formulas are how you do it.
• Total * 20% = tip

Rearrange Commonly used functions:
Collate • sum(range) - adds up all the numbers
Sort
• average(range) - calculates mean
Filter
Compare • median(range) - finds the middle
Derive info • max(range) - finds the largest number
• min(range) - finds the smallest number
These functions all work on groups
(ranges) of cells.

Rearrange Common formulas:
Collate • Addition: a1+b1
Sort
• Subtraction: a1-b1
Filter
Compare • Multiplication: a1*b1
Derive info • Division: a1/b1
• % change: (new-old)/old
• distance/difference: abs(value1-value2)
• Monthly balance:
balance*(1+rate/100/12)+credits-debits
