In a Google Docs spreadsheet, I'm looking for something like =EVAL(A1) where A1 is set to "=1+2".
I found out that in MS Excel there is an EVALUATE() function (which seems a bit tricky to use properly). But I could not find anything similar in Google Docs.
I also searched through the function list, but could not find anything helpful...
No, there's no equivalent to Excel's EVALUATE() in Google Sheets.
There's long history behind this one, see this old post for instance.
If you're just interested in simple math (as shown in your question), that can be done easily with a custom function.
function doMath( formula ) {
// Strip leading "=" if there
if (formula.charAt(0) === '=') formula = formula.substring(1);
return eval(formula)
}
For example, with your A1, put =doMath(A1) in another cell, and it will be 3.
I know this an old post. I'm just wondering, why nobody suggested:
myCell.getValue();
This will give you the result of the formula in myCell (3 in your example).
If you want to write the result to the cell (instead of the formula), you could use:
function fixFormula(myCell) {
myCell.setValue(myCell.getValue());
}
Short answer
As was mentioned previously, Google Sheets doesn't have a built-in EVALUATE function, but Google Sheets could be extended to add this function. Fortunately some SocialCalc files could be used to make this easier.
Script
On Google spreadsheet I'm sharing my progress. At this time I added the SocialCalc files that I think that are required and a couple of functions, and several test cases.
NOTES:
Google Sheets specific functions like FILTER, UNIQUE, among others are not available in SocialCalc as well as other functions like SIGN.
I think that the SocialCalc file should be replaced by those on https://github.com/marcelklehr/socialcalc as it looks to be updated recently. H/T to eddyparkinson (see https://stackoverflow.com/a/16329364/1595451)
Uses
The EVALUATE function on the linked file could be used as a custom function.
Example 1
A1: '=1+2 (please note the use of an apostrophe to make the formula be treated by Google Sheets as a string.
B1 formula:
=EVALUATE(A1)
B1 display value:
3
Example 2
To "EVALUATE" a formula like =VLOOKUP(2,A1:B3,2), at this time we need to use the "advanced" parameters. See the following example:
B1: '=VLOOKUP(2,A1:B3,2)
C1 formula:
=EVALUATE(B1,"data","A1:B3")
C1 display value:
B

If you want to evaluate simple math(like A1: "(1+2)*9/3"), you can use query:
=query(,"Select "&A1&" label "&A1&" ''",0)
Basic math sent to query's select is evaluated by query.

Maybe you can copy and paste the formulas you need from "jQuery.sheet". Moved to:

In the case of evaluating a function like
"=GoogleFinance("usdeur","price",date(2013,12,1),date(2013,12,16))"
This can be done this without evaluate by directly referring to other cells like this:
=GoogleFinance(A10,"price",E3,E6)
Simple hack to evaluate formulas in google spreadsheet:
select cells or columns with formulas
go Edit -> Find and replace...
check "Also search in formulas"
replace "=" to "=="
replace back "==" to "="
in the same "Find and replace" window uncheck "Also search in formulas"
formulas will evaluate! :)
Thank you for user3626588's workaround here and it does indeed work. Based off your instructions it looks like it can be simplified even further.
In Cell B1 Enter the following:="=sum(A1:A5)"
In Cell C1 Set a data validation and select B1 with dropdown option.
Now select C1 and select the formula from the dropdown, it will sum any values between A1 through A5 automatically.
I have a sheet where I was creating a complicated formula for multiple values and this process worked!
Thank you once again as I was trying to avoid a script since I have data that is being pulled by another program on my worksheet. Script function do not always run automatically in those situations.
Here is the trick. Insert formula in the required cell, then get retrieve that cell value and replace the already inserted formula with this new value.
function calculateFormula(row, col){
var spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getSheetByName("Sheet Name");
sheet.getRange(row,col).setValue("=sum(D6,C12:C14)");
sheetData = sheet.getDataRange().getValues();
var newValue = sheetData[row-1][col-1];
sheet.getRange(row,col).setValue(newValue);
}
How about just converting a column of expressions which are not preceded by a "+"?
92/120
67/85
etc.
It's a bit of a hack, but this works
get the formula from the cell;
set the formula back again; then
get the value from the cell.
var cell = sheet.getRange("A1");
var formula = cell.getFormula();
cell.setFormula(formula);
var fileCell = cell.getValue();
Awesome work around for google not having evaluate(). I have looked all around and besides script have found no other way to have a formula as a string on one sheet then use that formula on another. In fact everything I've seen says you can't. Would be helpfull if anyone reading this could repost around if they come to an appropriate question since I must have read a half dozen posts saying it wasn't possible before I just rolled up my sleaves and done done it. :) It still has a little clunkyness since you need two cells in the spreadsheet you want the formula to execute, but here goes.
Ok, some set up. We'll call the spreadsheet with the formula as string SpreadsheetA, call the tab the formula is on TabAA, the Spreadsheet you want to call and execute said formula SpreadsheetB. I'll use a multi-tab example, so say you want the sum of A1:A5 on SpreadsheetB tab: TabBA to be calculated on SpreadsheetB tab: TabBB cell A1. Also call the URL of spreadsheet A: URLA
So, in Spreadsheet A Tab: TabAA cell A1 put ="=sum(TabBB!A1:A5)", therefore the cell will display: =sum(A1:A5). Note: you don't need any $ in formula. Then in Spreadsheet B, Tab: TabBB, cell A2 put: =Query(Importrange("URLA","TabAA!A1"),"select Col1 where Col1 <> ''"). That cell will now display =sum(TabBA!A1:A5). Next to that, cell A1 of Spreadsheet B tab: TabBB, create a dropdown of the cell with the formula in B2 (right click cell A1, select data validation, for Criteria select: List from range, enter B2 in box to right). That cell should now be summing SpreadsheetB, TabBA, range A1:A5
Hope that was clear, I'm rather novice at this. Also important, obviously you would only do this in cases where you wanted to choose from multiple formulas on spreadsheetA, instead of TabAA!A1 say you had another formula in A2 also so your query would be =Query(Importrange("URLA","TabAA!A1:A2"). I understand in the simplistic case given you would simply put the formula where you needed the sum.
Edit: Something I noticed, was when I wanted to use a formula with double quotes the above scenario didn't work because when you wrapped the formula with double quotes in double quotes you get an error since you need single quotes inside double quotes. The example I was trying: if(counta(iferror(query(B15:C,"select C where C = 'Rapid Shot' and B = true")))>0,Core!$C$18+$C$10&" / ",)&Core!$C$18+$C$10&if(Core!$C$18>5," / "&Core!$C$18-5+$C$10,)&if(Core!$C$18>10," / "&Core!$C$18-10+$C$10,)&if(Core!$C$18>15," / "&Core!$C$18-15+$C$10,)
In that case I put another formula into Spreadsheet A TabAA cell A2 that read ="="&A1. Then, ajusted the importrange referance in spreadsheet B to reference that cell instead.
BTW, this absolutly works so if you can't get it let me know where your having problems, I don't do a lot of colaboration so maybe I'm not saying something clear or using the right / best terminollagy but again I've seen many posts saying this was impossible and no one saying they had found another way.
Thanx ~ K to the D zizzle.
Here is the working trick to evaluate the concatenated formula string. Use the formula cell as a data validation source for the target cell. Maybe it is not a fully automated solution. But evaluating refreshed formulas has been stripped down to just one click. You just need to reselect the value from the validation box when it is necessary. Many thanks to #Aurielle Perlmann and #user3626588 for the idea.
As an example, when you have set up dynamic multiple concatenations of such below formula in another sheet, this will work well with selecting validation option.
In my case, pressing enter twice is not userfriendly.
=({FILTER(IMPORTRANGE("https://docs.google.com/spreadsheets/d/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/edit"; "EXPENSES!A2:P"); INDEX(IMPORTRANGE("https://docs.google.com/spreadsheets/d/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/edit"; "EXPENSES!A2:P"); 0; 1) <> ""); FILTER(IMPORTRANGE("https://docs.google.com/spreadsheets/d/bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb/edit"; "EXPENSES!A2:P"); INDEX(IMPORTRANGE("https://docs.google.com/spreadsheets/d/bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb/edit"; "EXPENSES!A2:P"); 0; 1) <> ""); FILTER(IMPORTRANGE("https://docs.google.com/spreadsheets/d/cccccccccccccccccccccccccccccccccccccccccc/edit"; "EXPENSES!A2:P"); INDEX(IMPORTRANGE("https://docs.google.com/spreadsheets/d/cccccccccccccccccccccccccccccccccccccccccc/edit"; "EXPENSES!A2:P"); 0; 1) <> "")})

I have a workbook with a number of cells that have data validation specified as a dropdown list of allowed values. Using EPPlus, I want to be able to get for each such cell, the list of allowed values.
So far I've got:
ExcelWorkSheet.DataValidations gives me an ExcelDataValidationCollection, which is a collection of IExcelDataValidation items for the worksheet.
Each IExcelDataValidation has an Address property of type ExcelAddress which presumably references all cells that have that validation rule.
The step I'm stuck on is finding if a given cell is one of the cells included in the ExcelAddress
Any takers?
I'm currently using EPPlus 3.1.1.0, but can upgrade to a more recent version if necessary.
UPDATE
I didn't explain this clearly enough. Here's my situation in more detail.
Assume column C has some cells with list data validation. Some cells allow, say, "A, B, C"; other cells allow "D, E, F" etc. The range of cells for each data validation list is not contiguous, so, for example:
C2, C4, C7-C10, C20 may allow "A,B,C"
C3, C5-C6", C15 may allow "D,E,F"
I'm trying to determine which cells allow "A,B,C" and which allow "D,E,F" etc.
ExcelWorksheet.DataValidations contains ExcelDataValidationList items, one with values "A,B,C", one with values "D,E,F", etc.
ExcelDataValidationList.Address for the list "A,B,C" contains an ExcelAddress whose Address property looks something like: "C4 C7:C10 C2 C20 ...".
I want to determine if a given cell (say C6) is included in the range specified by this address "C4 C7:C10 C2 C20 ...".
Of course, I can String.Split on whitespace, and parse each item in the resulting list. But I was hoping there would be some more direct way of doing this, e.g.
ExcelAddress.Contains("C6")
or
ExcelAddress.Contains(6, 2) // row 6 col 2 = C6
Almost there, just check the IExcelDataValidation's specific type. Tested with EPPlus 4.1.0.0:
using (var package = new ExcelPackage(new FileInfo(path)))
{
var sheet = package.Workbook.Worksheets[1];
var validations = sheet.DataValidations;
foreach (var validation in validations)
{
var list = validation as ExcelDataValidationList;
if (list != null)
{
var range = sheet.Cells[list.Formula.ExcelFormula];
var rowStart = range.Start.Row;
var rowEnd = range.End.Row;
// allowed values probably only in one column....
var colStart = range.Start.Column;
var colEnd = range.End.Column;
for (int row = rowStart; row <= rowEnd; ++row)
{
for (int col = colStart; col <= colEnd; col++)
{
Console.WriteLine(sheet.Cells[row, col].Value);
}
}
}
}
}
Test worksheet:
Output:
one

I have this cell that has a formula which constantly updates its value. If the value gets to a specified number (For example: 10), I want to record its value on a different cell (For example: B2).
I'm guessing something like this would work:
If (Cell A2 = 10) {
change cell B2 into 10
}
I tried it inputting this formula on B2:
=if(A2=10,"10","")
The problem is, once A2 changes again, B2 changes as well. Is there any way to prevent this?
See if this works for you.
=if(A2=10,"10",if (A2<> 10,"10"))
Sorry if I misunderstood the problem. Try pasting this in the script editor.
function onEdit(){
var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet()
var target = ss.getRange("A1").getValue()//Sets the Target value i.e. 10
var r = ss.getRange(2,1) //gets A2 range
var val = r.getValue()// gets A2 value (in my test A2 is =F1 which is a calculated value(=D1*E1).
if(val==target){ //If the value = the target value
ss.getRange(2,2).setValue(val) //write the value to B2
}
}
I'm having some trouble with the below formula:
=IF(Data!X:X = 1,
IF(Data!H:H = "Horse",
IF(Data!U:U = A5, COUNT(Data!U:U)),0)
I need to check if column "X" in the excel sheet "Data" as the value of "1" if so, I need to check another column (in the same sheet) to see if it contains a particular text element(like: horse"), then I have to check to see if the column U in sheet "Data" contains the same value as my active sheet A5 if all the criteria match I need the count of how many times this occurs.
however my formula is only returning FALSE. I narrow it down to this part;
"IF(Data!H:H = "Horse")
now I double check , all the IF should end up as true.
Obviously I have something not right, any help would be great.
If you have Excel 2007 or later, you can use:
=COUNTIFs(Data!X:X, 1, Data!H:H, "Horse", Data!U:U , A5)
For Excel 2003:
=SUMPRODUCT((Data!X:X = 1)*(Data!H:H = "Horse")*(Data!U:U = A5))
Looks like the formula is incorrect (missing some of the false clauses in the if statements). This works for me:
=IF(Data!X:X = 1,
IF(Data!H:H = "Horse",
IF(Data!U:U = A5, COUNT(Data!U:U),0),0),0)
