So i have a question, does Talend have a option to keep the same format from a csv file, when we copy it on another TFileOutputExcel ?
For exemple my header style diseaper.
Thank you in advance !

I have a csv file which I convert, via a tmap to filter some things, to an excel file and I want to show only the first 16 lines of it.
Where can I set this?
In the input component property, set limit as 16.
You can use a "tsamplerow" for that after the csv input with the code "1..16"
I have a set of large xml files, zipped together in a singe file and many such zip files. I was using Mapreduce earlier to parse the xml using custom inputformat and recordreader setting the splittable=false and reading the zip and xml file.
I am new to Spark. Can someone help me how can I prevent spark from splitting the zip file and process multiple zips in parallel as I am able to do in MR.
AFAIk ! The answer to your question is provided here by #holden :
Please take a look ! Thanks :)
I am using powershell to read data from a .xls file. All goes well, no need to display the code. But I have an issue that I have no idea how to solve.
Some columns in the excel are not wide enough to display their data:
In reality:
2016.04.01
As the column is displayed when opening the file:
########
When I am reading from the excel, the cell content I get in powershell is actually ########, not the actual cell content (= a date in this case).
I am reading 1000's of Excel files, all with the same issue. How can I fix this in my code? Is there a flag I need to set that I don't know about?
Any help would be much appreciated!
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 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.
