Ive written the code I want and checked this works by only inputting 1 specific file, but now I am trying to write in a loop to do the same for all the files. I can assign the specific sheet to it. Unable to complete the action because of changes made to the page. offers. I cannot reveal my specific reason behind against all advices. Other MathWorks country You are right. Thanks! I can assign the specific sheet to it. Each spreadsheet is made up of multiple sheets of varying length, all that are continuously getting loger as I run simulations. Does someone have similar experience and what would be good work aorund to deal with this? I thought it was not possible to have "sheet" as an extra argument. If you need read an specific sheet of your file use the 'sheet' argument: myTable = readtable ('My_file.xlsx','Sheet','SheetName') on 6 May 2020 0 Link Translate The detectImportOptions function and specifically the spreadsheetImportOptions funciton might be able to help with that. Matlab readtable ignore nan. I however use table since it seems MATLAB promotes readtable over other approaches. I initially only use Range as argument and not Sheet, which works fine for readtable. The problem is now solved. firstCell = string(erase(lqPivot{1, (i-1)}. RTFD is cathartic for us but not very helpful for the OP or anyone else who comes looking for a solution in the future. Each Excel document contains a varying number of sheets, with the first sheet of every document named 'Summary' and then the sheets are named Trial1, Trial2, Trial3 etc. You are right. MATLAB 5.3.1 R11.1: It was released in the year 1999. But it failed when I tried to read data from a range on a different sheet. sites are not optimized for visits from your location. The values loaded by Matlab into table t are correct on my system, although I don't use this feature so I don't know how fallible it is. It seems it take ranges only, not even Named Range (global variable in Excel). sites are not optimized for visits from your location.

I even identify variable names in MATLAB from Excel to assign values in Excel Ranges to MATLAB table, Cell, or Struct. I have experimental data in multiple csv files. % just in cases your cell addresses contains Excel Cell absolute sign'$'. your location, we recommend that you select: . First, there are two ways to specify the sheet to read using the xlsread MATLAB command: Using the number of the sheet: [ numbers text textAndNumbers] = xlsread ( excelFileName, sheetNumber); The number of the sheet is "2" here because we want to read the second sheet (counting from the left). I even identify variable names in MATLAB from Excel to assign values in Excel Ranges to MATLAB table, Cell, or Struct. rngArea = strcat(firstCell, tDelimiter, lastCell); % I take this approach, so I don't need to change other codes for now (oh, well). In fact, the specification of Sheet is always required even I thought it was not the case. Reload the page to see its updated state. your location, we recommend that you select: . I have also attached Re3740000.txt because this text file is working and does not give me any NaN values. I thought it was not possible to have "sheet" as an extra argument. I am very much a 'RTFD' guy, and people who ask dumb questions that are documented get no sympathy from me when someone gives them short shrft. But it failed when I tried to read data from a range on a different sheet. Thanks! your location, we recommend that you select: . Based on I hope this help and any of you keeps throw any ideas. Use 'polyval' to get the values at the given interval. In my case, I use the first sheet (or any sheet) to identify sheet name, ranges (first cell and last cell) for each sheet. Thanks! Based on I want to experience the drawbacks you guys mentioned - I know it is rebellious! Ofcourse, I can use readmatrix or readcell, but then I will need to manupulate things to get the information of variable names etc. You need a little work to create range with first cell address and last cell address imported from Excel.

To make simple, I specify ReadRowNames column number, and ReadVariableNames true. Choose a web site to get translated content where available and see local events and Read and process multiple sheets from Excel to Matlab. https://la.mathworks.com/help/matlab/ref/readtable.html, https://la.mathworks.com/help/matlab/ref/readtable.html#namevaluepairarguments. I am going to deploy MATLAB portion to compiler and users will see one-sheet Excel and multiple-sheet Excel contains all data. Readtable is extremely useful when you want to include variable names and row names with data values. But, it can. should work when the number of rows is not the same; shorter rows will be padded with zeros. This MATLAB function creates a table by reading column oriented data from a file. I tried to get data via Readtable from Excel. But, it can. I want to experience the drawbacks you guys mentioned - I know it is rebellious!
