问题 How do I get the last character of a string using an Excel function? 回答1: No need to apologize for asking a question! Try using the RIGHT function. It returns the last n characters of a string. =RIGHT(A1, 1) 回答2: =RIGHT(A1) is quite sufficient (where the string is contained in A1). Similar in nature to LEFT, Excel's RIGHT function extracts a substring from a string starting from the right-most character: SYNTAX RIGHT( text, [number_of_characters] ) Parameters or Arguments text The string that

问题 My searches for answers have been limited by my lack of knowledge of the appropriate terminology. My goal is to count the number of times a specific username appears in one column AND the number 1 appears in another column for that user. I attempted to use COUNTIF, but it doesn't seem to format for that purpose. What I'm needing is to count the number of instances "username" appears in column K when "1" appears in column Q. 回答1: If you have =COUNTIFS (you don't mention which version of Excel)

问题 I have data in text form that I need to encode/convert to numeric form according to rules I defined. To clarify: Need formula for output column so that it compares original text data with text-number encoding rules and returns numeric value of text in each row. 回答1: Put this in C3 and drag down: =INDEX(F$2:F$6,MATCH(A3,E$2:E$6,0)) 来源： https://stackoverflow.com/questions/34124334/text-encoding-converting-to-numeric-based-on-user-defined-rules-in-excel

问题 I have a total data set that is for 4 different groupings. One of the values is the average time, the other is count. For the Total I have to multiply these and then divide by the total of the count. Currently I use: =SUM(D32*D2,D94*D64,D156*D126,D218*D188)/SUM(D32,D94,D156,D218) I would rather use a SumProduct if I can to make it more readable. I tried to do: =SUMPRODUCT((D2,D64,D126,D188),(D32,D94,D156,D218))/SUM(D32,94,D156,D218) But as you can tell by my posting here, that did not work.

问题 I am trying to use COUNTIF in Excel to find how many items in a range match the contents of a separate cell. The idea is, the range contains everyone's answers to a given question (a one-word, non-numeric answer); the comparison column contains the correct answer. I want a count of how many people got the answer correct. I tried: =COUNTIF(C16:BT16,"=BU16") But it appears COUNTIF won't let me reference a cell with the criteria in it -- it requires the match criteria directly in the formula,

问题 28 10 | 100 29 210 30 40 20 | 84 41 130 42 43 30 | 75 44 740 45 46 40 | 73 47 220 How can I sum every 3 rows A29+A41+A44+A47+... I tried various suggestions like this and this one but couldn't figured it out. In addition, is there any way to extract the second part, to a different column, of the other rows? I mean 100, 84, 75, 73, ... 回答1: In a cell as a standard non-array formula, =SUM(INDEX(A29:A48*NOT(MOD(ROW($29:$48)-29, 3)), , )) The ROW($29:$48)-29 is the position within A29:A38 and

问题 I have a client that has a simple yet complicated request for an excel sheet setup, and I can't for the world thing of where to start. I'm drawing a blank. We have a data range. Example: Quarter Data 2010Q1 1 2010Q2 3 2010Q3 4 2010Q4 1 I have a chart built on top of that. Change data, chart changes, protect worksheet to keep other idi... er... users from changing old data. Simple. What I want to have happen: When I add the next Q1 below Q4, the chart "automagically" selects the most recent 4Q

问题 I have never really used Excel before but this seems like it should be possible. I have an ongoing document where I will be adding values every day, but what I want it to do for every 7 rows I want it to sum those values and add the sum of the 7 rows to a different column/row, e.g., Row B7:B14 Sum in D12 Row B15:B22 Sum in D13 And then when I start adding data into B23 I want it to add the sum to D14. 回答1: In D12, put =SUM(OFFSET($B$7,(ROW()-12)*8,0,8,1)) and fill down column D as far as you

问题 I want to calculate a moving average of the last, say 20, numbers of a column. A problem is that some of the cells of the column may be empty, they should be ignored. Example: A 175 154 188 145 155 167 201 A moving average of the last three would be (155+167+201)/3. I've tried to implement this using average, offset, index, but I simply don't know how. I'm a little bit familiar with macros, so such a solution would work fine: =MovingAverage(A1;3) Thanks for any tips or solutions! 回答1: {=SUM((
