how do I insert special characters into a google docs spreadsheet. For example the symbol for the euro or pound.
On an Amrican keyboard there are no keys for characters such as € and £ ... so one has to resort to special key combinations / codes to make entries for such special characters.
In the following I have used special characters such as the € and the £ in TEXT as well as in FORMULAS

Use the SUM IF function to add only those cells corresponding to a non-empty cell in the specified range.
for eg. in column C i have values ( numbers, text and empty cells). I want to add all the cells in column D that have non-empty cells in column C.
I know how to search for blank cells and it works. I use SUMIF(C3:C10,"",D3:D10) . This sums all values in column D for which column C is blank. I want to do the opposite.
would appreciate any help
In the following ...
I have a solution using SUMIF function in Sheet1
a solution using the FILTER function in Sheet2
Sheet3 has a solution using the QUERY function (by first convering all entries in range C:D to TEXT)
Sheet4 has another solution using the QUERY function and aggregating column D
by the way in this case solutions using the SUMIF and the FILTER function are so straight forward
I have included the solution using the QUERY function out of interest especially since column C is mixed TEXT, NUMBERS, and BLANKS

Substituting a part of the formula with the content of an adjacent cell
I am trying to modify my [code]=importXML("http://www.google.com/search?q=B1&num=100", "//a[@class='l']/@href")[/code] and "B1" is where formula should grab the content from... I have tried a multiple number of ways to fix the problem. But what I would want is that I modify the B1 cell and it refreshes the formula. Trying to simplify the process for my co-workers. Is this doable?

ignore [code] part
So the 2nd column is what the result should be like, but if you try substituting "Swiss Colony" with B1, it just searches for B1. Which makes sense because it all enclosed in "" , so I tried breaking it down into separate parts to make B1 an active element, I succeeded with that in D2 and the following. But it wont execute it, because google reads is an an outcome not an input...
ImportXML formula in cell B2 uses the string Swiss Colony
I have created a formula in cell C2 which uses the variable in cell B1 instead of the literal string Swiss Colony

It would be cool, if anybody can help me here. Unfortunately, I didn't find anything on the web so far :(
I have a table and in column D, I want to store multiple numbers as a comma separated list, e.g.:
In another sheet, I want to count how many cells contain a certain number. What I did so far is:
If D is formated as numbers and only use one number (instead of a list) in every D-cell, this works fine.
On the other hand, the formula does not work anymore for comma separated list that is formated as text.
Interestingly, also single numbers don't work if they are formated as text.
In the following solution I have computed Y for occurrence of X with different solutions in

I'd like to create a data table that holds the historical prices of a list of stocks, getting the closing price for each stock for a given date.
So, say A2 - A7 holds the following:
and cell B1 holds 2/2/2011
What I'm trying to acheive is generating a table like this:
2 DELL 158
3 MO 49
4 PG 241
5 JNJ 12
6 CSCO 741
7 XOM 54
I don't know about where you got the numbers in your column B from
I have provided a formula in cell B2 that is then dragged down for copying as far as needed

chandan.ssj further added:
now in the same spreadsheet if I wanted to add few more attributes, (for example open price), in column C, then what will be the formula used?
I have added Sheet2 where I have setup the formula for close and open prices ... in fact you can extend it for other GoogleFinance function attributes as well.

I was soooo close setting up reference cells in column A of 1/1/11, 1/16/11, 2/1/11, etc., and then calculating the end of a pay period in Column C with =workday(A2,-3) and the beginning of the next pay period in Column B (next row) with =workday(C2,1). Unfortunately, it turns out this organization works on Saturdays, so I need to be able to return a value if it falls on a Saturday, but skip Sundays and return the date of the following Monday.

I tried it with pivot table report - there I could group vendors and with a filter I could sum the sponsoring.

Sometimes in column V i have "*****" which are not numeric.

Well, I noticed the pattern that starting with column F you want to sum up the value in every 8th column in row 8 and once a formulas has been developed do that for row 8, then the formula can be replicated for row 9.

Pettere said:
I am trying to apply two filter functions in Google Docs.
•Column (A) contains new data
•Column (B) contains filter data, i.e. cells with text that should not be included in column C
•Column (C) is the outcome, i.e. column A minus all the cell data in column B
Example: www.goo.gl/idyXy
I use this formula in column C: =ARRAYFORMULA(SORT(UNIQUE(IF(ISNA(MATCH(A2:A,B2:B,0)),A2:A,""))))
It works well in the sense that it filters data (in this case e-mail addresses) that should not be included in column C. However, I would also like to be able to filter whole domains, i.e. if the domain example.com is listed in column B then all addresses from column A ending with example.com should be excluded from column C.

Update by Petteri:

In column A I have new e-mail addresses.
In column B I have a filter list consisting of e-mail addresses and domains.
Column C should be the result of all the e-mail addresses in column A minus the e-mail addresses in column B, however the e-mail addresses from column A which have a corresponding domain name in column B should also be excluded.


A: jimmy@itcompany.com, arne@itcompany.com, fred@webcompany.com
B: jimmy@itcompany.com, webcompany.com
C: arne@itcompany.com

Column A is the new list.
Column B is the filter list (e-mail addresses and the occasional domain)
Column C is the result, A minus B.

I have a painting company and I use a google form to gather information about the rooms my clients want painted. Every time I submit a new form the information is put into a google spreadsheet that I use to estimate job costs. I have the room measurement the clients name and address and my calculations all on sheet 1. Every column is labeled the same, the information just varies row to row.
So the first customers information gets put into row 1. The next customer is in row 2 and so on. This is sheet 1.
Sheet 2 I have as a Estimate form that I can print and give to the customer. It has my business name, the estimate # and the total job cost. Lets say I have the formula in the "name" cell on my estimate to be. =Sheet1!G16 which returns "Heather" I complete the rest of the cell formulas to pull various information from row 16. Such as Job description, total cost, etc. I print the form and I am done and now I need to print another estimate for the next client whose information is all on row 17.
Is there a way I can change all the number 16's: A16, G16, L16, to A17, G17, and L17 automatically? I don't want to have to waste my time changing the formulas every time I have to create a new estimate.

Part of Sheet1

Part of Sheet2
as exists now with formulas based on row 16 as a static row

Part of Sheet2
making row number used in the formulas as a variable
so for estimate for next row down 16 if changed to 17 will update results for row 17

Create different operations based on a set of criteria?
Hopefully I can explain this; I have tried using IF, IFERROR and AND statements, but I'm getting nowhere.
I would like three cells:
One is an "input" cell which will contain a decimal between 0 and 1
The other two are the "big" and "small" product cells. (The "big" cell will be added to by a different formula also.)
The criteria I need are these:
If the input is between 0.0 and 0.14, do nothing
If the input is between 0.15 and 0.42, add 1 to the "small" cell
If the input is between 0.43 and 0.64, add 2 to the "small" cell
If the input is between 0.65 and 0.85, add 1 to the "big" cell and subtract 1 from the "small" cell
If the input is between 0.86 and 0.99, add 1 to the "big" cell
I imagine this is a bunch of nested statements?

The data is Currently like this:
Y D =IF(A1=Y;B1;C1)
The formula copies down the entire sheet. Basically the idea is to only update collumn C if collumn A is a certain value, otherwise leave the currently displayed data in Collumn C alone. However, in Google Docs I can't use that formula since it doesn't allow iteration.
I'm trying to find a way to do the same thing within the bounds of Google Docs but having no luck. Any help would be appreciated. Using additional hidden cells would be fine but I'm not sure how to do that either, everything I have come up with thus far winds up with a circular reference.

I'm working on a self test containing ten multiple choice questions. Each answer gives a certain score, and I'd like to automatically calculate an overall score for each respondent.
I'm thinking of the following solution:
- Replace all answers in the spreadsheet with scores
- Add up the scores for each contestant
The thing is: I don't know how I can replace certain answers for scores for each question (different questions have different scales).
I hope you can help, or maybe you see a different solution.

I use the form feature indeed, and I'm working on a translated (into Dutch) version of the Edinburgh Depression Scale: 

As you can see in the PDF, each answer has a score and sometimes the first answer gives the lowest score, and with other questions the first answer gives the highest score. In Google Docs, I'd like to translate the given answers into the applicable scores without a lot of manual work for each respondent. How can I use formulas to give the right scores to the different answers? 
In the following illustration I have used three questions ... each question is a multiple choice question with 4 options. Questions 1 and 2 have a score of 0,1,2, and 3 for options 1 through 4 respectively and question 3 has score of 3,2,1, and 0 for each of the options respectively. I created the Form originally for the fields shown with Gray headers and then later on I added additional columns with brown colored background for formulas for scores by question and then a column with yellow colored header for Total Scores for each respondent.

here is the Form that was created for this illustration

Column A with their names hyperlinked to a specific alternate URL ending in their alphanumeric (hyperlink("http://www.newphp?id=123xyz789","Name Submitted")
Column B with just their unique 9-12 digit alphanumeric, which is at the end of the URL they submit, after a "=").
...and where B has two entries for A, just return the most recent A (if different by way of initials, nickname, fullname, etc...)
Is this possible?

I'm working on a dashboard and I have 2 arrays. One with unique values and another one with many values that match the first array. I want to know how many values in the second array match the values in the first array. I know how to do this on VBA, but I'm not allow to use it.
Here is the example:
here, the result of what I want would be 6 (3 a, 2 b and 1 c)
I appreciate any help.
Following is a solution is Sheet1 using Google Docs Spreadsheet

yogi_Create BarChart That Sums Values In Column With Similar Labels

I have two columns: A and B
In column A, there are dates. e.g.:
In column B, I have integral values:
For each value in column B who's corresponding label in column A is identical, generate a sum of those values and represent that sum in the bar graph. So the result (using the data above) for a bar graph would be:
Label: 5/5/2011
Value: 82
Label: 5/6/2011
Value: 109
Label: 5/7/2011
Value 76
This would result in a bar graph with 3 bars (instead of 4 like you normally would see). How can I do this?

In the proposed solution here, in Sheet1 I added two columns C and D
in column C I extract unique values from column A, and
in column B I sum up the values in column B  for similarly labeled entries in column A
then I create a Bar Chart fro range C:D

I added Sheet1a(WithOpenEndedRanges) to generalize the solution so that when more rows are added tn the data range the BarChart automatically updates.
