            Since formatters generally try not modifying the contents inside strings too much, this would be tricky in an automated way without seeing the actual code, would be complicated, and would probably have hiccups (IMO).

            If the only reason using TAB doesn't solve your answer is because it uses 4 spaces, you can temporarily change it to using 2 spaces To do this you will need to do the following:

            1. Settings ->Editor -> Code Style -> Python -> indent -> 2.
            2. Settings ->Editor -> Code Style -> Uncheck Detect and use existing file indents for editing

            FileNotFoundError when load_workbook using the passed over filename
            Asked 2022-Feb-17 at 06:46

            I def a function and passed over its argument from a for loop, and got the FileNotFoundError: [Errno 2] No such file or directory: 'revenue.xlsx'.

            The for loop works and the function also works when separately print them. So I am assuming something is wrong when passing over the argument.

            Here's my entire code.

            You need to supply the path to the file as well (me thinks).

            You can return data in the output parameter and return result of data loading as a primary method output (true for successful load, false for error that is fine):

            XmlValueDisconnectedException when remove Formula
            Asked 2021-Apr-14 at 11:12

            I trying to reade an Excel file with java poi. I iterate through the rows and then through the cells. To reade the cell i use this method:



            Answered 2021-Apr-14 at 11:12

            According the StackTrace, there is a problem with a shared formula.

            If you have formulas =D6, =D7, =D8, ... =D219, =D220, ... and so on in column D, then not for all cells the complete formula is stored. Instead only one cell stores the complete formula and following cells only store shared reference to the formula.

            In OOXML this looks like so :

            In XML of cell D8: D7

            In XML of cell D9:D300:

            This Excel behavior tends to be fragile if somewhat else than Excel manipulates rows containing such shared formulas.

            Cell.removeFormula is a pretty new feature in apache poi. It might be buggy. But as it is designed it should know about such shared formulas and respect those. So to get what really leads to that XmlValueDisconnectedException one would need the Excel file. There one could have a look into the sheet's XML and check whether someting in the shared formula's XML is different from the default which is expected by XSSFCell.convertSharedFormula.

            But do you really need Cell.removeFormula? Because if the goal is simply to get the cashed formula value instead of the formula string itself but to avoid evaluating, then one could get that cashed formula value the same way as the other cell values but dependent on the cached formula result type.

            How to add duplicates or merge entries in a complex list?
            Asked 2021-Apr-08 at 21:03

            I have a problem that I thought would be easy to solve but after a couple of days of failed attempts I'm asking for help.

            I have a table in Excel that looks like this:

            Transaction Date Bank Account Balance 44287 Account 1 500 44287 Account 1 -700 44287 Account 2 -200 44286 Account 1 300 44286 Account 3 -150

            The table represents multiple bank accounts and I want to obtain the cumulative balance for each date across all accounts. So for example the output I expect is:

            Transaction Date Balance 44287 -900 44286 150

            If there are multiple transactions from the same account on a given date, for example on "44287" the balance of Account 1 had two values, so I would take the maximum absolute value which is -700 (and ignore 500). I'm using the default date number notation from Excel for simplicity.

            I've exhausted all my options in Excel so I created my own simple Console App in C#.

            This is what I have so far.

            I'm reading the input from Excel into a var data = new List>();. The first outer list stores the columns and the second inner list stores the rows. So for instance data[2][3] would equal -200.

            In Excel, you can do this using Power Query.

            See the comments and explore the Applied Steps window to understand the algorithm, which I think is what you want:

            You may need to edit the data types to reflect decimal numbers and dates.
