I am trying to read data from text file (which is output given by Tesseract OCR) and save the same in excel file. The problem i am facing here is the text files are in space separated format, and there are multiple files. Now i need to read all the files and save the same in excel sheet.
I am using MATLAB to import and export data. I even thought of using python to convert the files into CSV format so that i can easily import the same in MATLAB and simply excelwrite the same. But no good solution.
Any guidance would be of great help.
thank you
To read a text file in Matlab you can use fscanf or textscan then to export to excel you can use xlswrite that write directly to the excel file.

I have files with extension .fid
I want to read the data off of the file with matlab preferably. Is there anyway to do this with a custom file format like this?
If not, is there any other way I can transform this custom file format into something else? such as .csv?
Not familiar with this file type, but if it's human-readable, if you can open it in text editor and see the data, then there shouldn't be a problem. You can textscan to import data, if it's properly formatted, or fileread to import the entire file as string. You can even use uiimport to import data in interactive mode. Check MATLAB documentation for Data import and export
I am trying to use xlsread functioin to read spreadsheets of 6000x2700 (xlsx file).
I have two questions:
First, when I use something like
[num,txt,~]=xlsread(input_file,input_sheet,'A1:CYY6596')
Matlab keeps showing 'busy' and lose response (while I can open it in excel within 30 seconds).
Is there any solution If I don't want to loop through ranges of the xlsx file? In other word, can I just dump spreadsheet of this size into matlab using xlsread?
Alternatively, Maybe I can use loops to read these files range by range, but I cannot identify the last column of each of the spreadsheets unless I read the whole file first. Therefore, If I cannot identify the last column, it is hard to make loops and do my interpretation on the file.
So My second questions is: Is there a way to identify the last column of the spreadsheet without reading the whole spreadsheet?
Thanks.
EDIT:However, if I run a similar code which only reads first 400 columns ('A1:RY6596') of the spreadsheet, such problem doesn't happen.
which version of matlab you are using?
matlab has a problem to load bix excell file.
convert the excell in csv and use M = csvread(filename).
You can try to convert .xlsx into .xls also.
You can Try the tool in
File Exchange
I have the following problem:
1) consider a dataset in Stata whose variables are of type float, double, byte. Observations are all "numbers"
2) I want to save the dataset in .xls format; hence I type in Stata export excel using ".../A.xls"
3) When I open A.xls in Excel, the cells have format "General"
4) I want to load A.xls in Matlab but I get the error Unreadable Excel file: XLS File contains unicode text which is not yet supported
5) If, instead, before going to Matlab, I apply the format "Numbers" to the cells in Excel, A.xls can be easily loaded in Matlab.
Any suggestion on how going directly from Stata to Matlab in this particular case?
With Stata 14, you can save the file as xlsx instead of xls. In this case, the error message on OSX disappears. On Windows, xls seems to work fine as well.
is the problem you having just from xlsread? did you try readtable?
I want to create a Excel supported file which contains strings and images programmatically. I tried to create a .csv file, but I am not able to .csv file with both string and image.
There are many possibilities. The easiest way is to create CSV-Files but you have to take care which seperators excel uses. For checking that you should create a spreadsheet in excel and save it as csv and take a look into that file using any text-editor.
Another approach is to use SpreadsheetML and here a link to the msdn XML Spreadsheet Reference
Otherwise just create a simple xlsx-file with excel, unzip that file and take a look into that the unziped files.
I want to automate Excel using Perl to do the following task(s):
For a list of Excel .xls files, do the following:
Open the file
Set Format to CSV
Save the file under the original filename and directory, but replace the extension "xls" with "csv"
Close the file
End
I found how to open files, even how to save them. I did not find how to change the fileformat/save as a different format. There shall be no user dialogs popping up, it should be fully automated. The Excel file list I can generate myself, a parameterized "find" or maybe "dir" should suffice.
If you are using Excel automation a great help is Excel itself. Use the VBA environment (Alt+F11) to get help for the Excel objects you want to use.
The objectbrowser (F2) is very valuable.
Workbook.SaveAs([Filename], [FileFormat], [Password], [WriteResPassword], [ReadOnlyRecommended], [CreateBackup], [AccessMode As XlSaveAsAccessMode = xlNoChange], [ConflictResolution], [AddToMru], [TextCodepage], [TextVisualLayout], [Local])
Searching for CSV in the object browser will show Excel constants with their values, since you probably cannot use these Excel constants in Perl.
See Spreadsheet::ParseExcel and xls2csv, they will help you.
