I'm trying to add a spreadsheet editing function in my iOS app. I am using a gridview to display (not relevant to the question) and I am using LibXL to load the data into the view. That part all works very well but I have no way to calculate the formulas after a cell has been modified.
It appears that when I write a formula with LibXL it is not calculating the new value, just setting the formula value (a string). So when I try to read the number value from that cell it is still set to the last computed number (from excel).
Likewise, if I create cells with numbers and a formula cell to SUM them, it is never actually computed which reads a 0 number value until it's opened in Excel.
I was hoping LibXL was the silver bullet to my problem, but now I'm stuck with just the formula string value (i.e. "SUM(A1:b2)" ) and the last computed value.
I would love it if LibXL simply DID compute values and I just have it all wrong, but I can't see any documentation that says otherwise. If that's not the case are there any Obj-C, C, or C++ libraries that I can use to match the Excel Formula syntax and compute these values?
Just adding my previous comment as an answer:
Dave Delong's DDMathParser has the option to add custom functions, check it out here: http://github.com/davedelong/DDMathParser

I have a column of values that are a number out of 10. So, it could be 2/10, 3/10, 4/10 and so on, all the way up to 10/10. To be clear, these are not dates, but simply showing how many questions the student answered correctly out of 10.
I'm trying to use conditional formatting to highlight them a certain color depending upon the score they got. For 9/10 and 10/10, I'm wanting to use a certain color, but it doesn't seem to be working with REGEXMATCH or with OR. Also wanting to highlight all scores that are 6/10 or lower. I know that I could make this work by applying conditional formatting for each and every score with text contains but the problem I'm finding is that it thinks it's a date.
Is there a way to match multiple scores out of 10 using REGEXMATCH?
Link to Sheet
select column and change formatting to Plain text
now you can use formula like:
=REGEXMATCH(A1; "^9|10\/")
I'm trying to nest an IF function inside a vlookup to filter data based on a cell in another sheet.
The ideal functionality would be for the cell to return data if it meets a specific criteria otherwise leave it blank.
This is what I have so far:
=IFERROR(vlookup(E2,IF('internal_all[Paste Here]'!H3="Indexable",'internal_all[Paste Here]'!A:AB,""),28,0))
Currently, it doesn't work but instead I get an error "VLOOKUP equates to an out of bounds range".
Any help would be much appreciated.
Here's a copy of my gsheet: https://docs.google.com/spreadsheets/d/13mcOOHIP6-YQKOhE_LHnmu3-7bSNKzvCSTVZ5BnTxPA/edit#gid=0
Here's an example of the error I'm running into:
If I understand your question correctly...Then all you would need to change is where you put the if. Including it in the Vlookup will mess with the size of range ie. A:AB has a size of 28 but "" has a size of 0. I would also change your formula to an array so you don't have 6000+ formulas calculating. Finally, I would add an array_constrain to stop the array at the end of your dataset. Here is a working example:
=Array_Constrain(ArrayFormula(IF('internal_all [Paste Here]'!B2:B="Indexable",vlookup(E2:E,'internal_all [Paste Here]'!A2:AB,28,0),"")),CountIf(A2:A,"<>"),1)
I also included that formula in H2 of your "internal links point to canonicalised URLs" tab. Good luck!
Edit:
After looking at the setup again, this updated formula should work.
=Array_Constrain(ArrayFormula(if(VLOOKUP(E2:E,'internal_all [Paste Here]'!A:B,2)="Indexable",vlookup(E2:E,'internal_all [Paste Here]'!A2:AB,28,0),)),CountIf(A2:A,"<>"),1)
Also, here is an updated Indexability formula for column G
=Array_Constrain(ArrayFormula(IFERROR(vlookup(G2:G,'internal_all [Paste Here]'!A:B,2,0))),CountIf(A2:A,"<>"),1)
MY GOAL:
parse a MM/DD date from the result of a vlookup so that it can be used in a project plan
BACKGROUND:
The vlookup result contains multiple values separated by a "•" (I don't need all of them)
The value I'm looking to parse is not always in the same location in the vlookup result (otherwise I could use the RIGHT formula)
There is a finite number of the values I'm looking to retrieve (and I know them already)
The value that I'm looking to retrieve contains some text with a date range; I only want the first four values in the date range (MM/DD)
I'd like to achieve all this with a single formula with the result in a single cell
CURRENT FORMULA
The formula that I've been working on that is not working is:
=ARRAYFORMULA(if(iserror(search(Iterations!D2:D7,(VLOOKUP(A2,'Results {2596503}'!$C$2:$L$183,3)))),,))
I've set up a sheet called "Erik Help" with the following formulas in B2 ad C2:
=ArrayFormula(IF(A2:A="","",MID(VLOOKUP(A2:A,data!A2:B,2,FALSE),FIND(REGEXEXTRACT(VLOOKUP(A2:A,data!A2:B,2,FALSE),"[0-9]-[0-9]"),VLOOKUP(A2:A,data!A2:B,2,FALSE))-4,5)))
and
=ArrayFormula(IF(A2:A="","",MID(VLOOKUP(A2:A,data!A2:B,2,FALSE),FIND(REGEXEXTRACT(VLOOKUP(A2:A,data!A2:B,2,FALSE),"[0-9]-[0-9]"),VLOOKUP(A2:A,data!A2:B,2,FALSE))+2,5)))
respectively.
They may be longer than actually needed, but you did not share realistic results in Column B or list which symbols may appear in Column B other than in the date; so I tried to account for either a hyphen or a forward slash possibly appearing in Column B in places other than within the date span.
Your analytics sheet also shows a formula that is sorting the results from data!A:A. So even though in your example the original data order happens to be the same as in analytics!A:A, that is not a given (again, based on your formula). Therefore, the VLOOKUP is also necessary.
You did not indicate whether you need to further use these returned date-snippets in calculations, or whether you just need to view them. So the results generated in "Erik Help" are text.
If you want usable numbers/dates, you add further issues that would need to be controlled for in the formula, because you'll only be extracting month and day, not year. That's fine right now. But what about when the date range to be extracted is "12/28-01/13"? If you simply make these values/dates, they will both be assigned to the current year. So the end date here will wind up being earlier than the start date.
Because of this, I've added a second sheet, "Erik Help 2," which contains extended formulas to account for these cases while still returning the date format you want as actual dates which can be used in calculations.
EDIT
(following your note on the sheet: "I would like to remove col b altogether and nest in the formulas in col c and d")
You can adjust the range B2:B by replacing it with your already existing formula in B2.
The new adjusted formula will become
=ArrayFormula(IFNA(SPLIT(REGEXEXTRACT(VLOOKUP(ARRAYFORMULA(sort(unique(data!A2:A))),data!$A$1:$C,2),"\d+\/\d+-\d+\/\d+"),"-")))
Original answer
You can use the following formula:
=ArrayFormula(IFNA(SPLIT(REGEXEXTRACT(B2:B,"\d{2}\/\d{2}-\d{2}\/\d{2}"),"-")))
Make sure you format the results as Date.
(Please adjust ranges to your needs)

So I have searched through several different questions related to this. None of them seem to be asking exactly what I'm looking for and none of the solutions I've found have worked for me thus far.
I have several columns of data (Player names) where each column's values are generated from a formula in the 2nd row of that column. The 1st row is a header (Game name). This whole range is the collection of which players are willing to play which games. These are columns D-J(ish, the list is dynamically generated with another formula, based on form responses)
I have another range of data where the 1st column is the Player and the 2nd is the player's PREFERRED game. This data is also generated with a formula based on form responses. These are columns A-B.
Here's what I'm trying to do
Using conditional formatting in columns D-J, I want to highlight the player's name if this game (in row 1 of this column) is their preferred game (range A2:B).
I've tried several different variations of VLOOKUPS, MATCHES, and FILTERS in the conditional formatting, but so far nothing has worked. The problem I run into every time is that I can't figure out how to reference the cell that the formatting is applying to, but still have it reference each individual cell over the whole range.
I know I could do this if I applied an individual conditional formatting to each individual cell. However that is a very time consuming and inelegant solution to this issue considering I'm expecting my data range to be much larger in the future. I need a conditional formatting formula that will work across the whole range or , at the very least, for an entire column.
This is a mock of what I'm trying to accomplish:
This is a link to a mock of my sheet so that you can clearly see the data layout and specific formulas I'm using:
https://docs.google.com/spreadsheets/d/1wy1T6dWJwNC_EfdCAbkuxtkJH7y4Cg3x4IyEk6R567M/edit?usp=sharing
use:
=REGEXMATCH(D3, TEXTJOIN("|", 1, FILTER($A$3:$A, $B$3:$B=D$2)))
In OpenOffice.org Calc, I would like to apply a formula to a column that references a cell from the same row but in a different column. I.e., =C1*48 in cell D1, but I want all cells in column D to do this without having to copy the formula to each one manually. Or another way of saying it, for each cell in C that has a number, I want to fill in the corresponding row-cell in D with a formula value based on that number. So far, all I can see from the documentation is that I'd have to copy/adjust the formula for every new row in the spreadsheet. And since I have 4 such columns that need calculation, this will get to be tiresome. I have little experience with spreadsheets at all, so I'm hoping that my problem is actually very simple, and that I just am looking at the wrong parts of the documentation.
I don't have OpenOffice in front of me, but it tries really hard to be Excel like in many ways, so usually assumptions about Calc based on Excel are fairly close to reality.
In Excel, a formula in cell D1, that points to a cell in C1, is treated as a relative reference - that is, one column back from where I am now. So when that formula is filled into other cells (either by Fill Down, or dragging the little handle in the corner of the cell outline, or by copy-pasting the formula into a range of selected cells) the new formulas are similarly treated, by default, as referring to the cell that is one column back from them, in the same row.
To force a formula to use an absolute reference, one specifies the cell address with a dollar sign - $C$1 will always point to (use) the contents of cell C1, regardless of where the formula ends up. ($C1 and C$1 are alternates that allow one parameter of the address to change in the usual relative sense while fixing the other half in place... this probably isn't important to you yet).
In other words, I'd expect that you can type the formulas in the first row of your OpenOffice Calc sheet and copy them down to the rest of the row, and things will just work.
If you want to extend your range down you can do this by calculating the first 2 cells with your formula and then highlighting them. You now grab the little square on the bottom right of the highlighted area and drag that down, across or both.
If you have a specific cell (e.g. D2) which you wish to have remain in all the cells you extend your range to, then in your 2 initial cell calculations use the following:
Extending Down
=G2*D$2
=G3*D$2
Extending Across
=G2*$D2
=H2*$D2
Extending Down and Across
Use $D$2
From your question it seems that you are trying to apply the same formula on whole row (or column) of cells and show the result on another row (or column).
The best way to do this is to use something called array formulas or array functions (in libre office). This link has very good explanation - https://help.libreoffice.org/Calc/Array_Functions
The way you would implement this in your case is
Type this formula in cell D1
=C1:C30 *48
and press ctrl + shift + enter
The formula now looks like this with the flower braces {..}
={C1:C30 *48}
and the formula gets applied all the way from D1 to D30.
You can even extrapolate the same concept to a whole matrix (for example: A1:C10)
(The way to tell excel/open office/ libre office that you wrote an array formula is to press ctrl + shift + enter. Never press enter as that will break the array function and convert it to a regular function)
