export-to-csv

Initial Question: I'm looping through a couple of thousand pickle files with Python Pandas DataFrames in it which vary in the number of rows (between aprox. 600 and 1300) but not in the number of collumns (636 to be exact). Then I transform them (exactly the same tranformations to each) and append them to a csv file using the DataFrame.to_csv() method. The to_csv code excerpt: if picklefile == '0000.p': dftemp.to_csv(finalnormCSVFile) else: dftemp.to_csv(finalnormCSVFile, mode='a', header=False) What bothers me is that it starts off pretty fast but performance decreases exponentially, I kept a

I have a .xls I need to convert to .csv The file contains some date columns. The format on the date is "*14/03/2001" which, according to Excel means the date responds to regional date and time settings specified for the OS. Opening in Excel you see: 20/01/2013 01/05/2013 Save as... CSV Open in notepad: 01/20/2013 05/01/2013 I have temporarily fixed by setting date formats to "14/03/2001" (no *) but even some other custom formats with no *, like "d/mm/yyyy h:mm" get mangled when saved to CSV. Although keeping this in mind http://xkcd.com/1179/ In the end I decided to use the format YYYYMMDD in

I need to convert an XLSX file to another CSV file. I've done a lot of research on how to do this process, but I did not find anything that suited me. I found this Github Gist only Convert an Epplus ExcelPackage to a CSV file That returns an Array of binary. But apparently it does not work any more. I'm trying to load Array using LoadFromCollection FileInfo novoArquivoCSV = new FileInfo(fbd.SelectedPath); var fileInfoCSV = new FileInfo(novoArquivo + "\\" + nameFile.ToString() + ".csv"); using (var csv = new ExcelPackage(fileInfoCSV)) { csv.Workbook.Worksheets.Add(nameFile.ToString()); var

So, I have a file that's designed to parse through a rather large csv file to weed out a handful of data points. Three of the values (out of 400,000+) within the file is listed below: Vehicle_ID Frame_ID Tot_Frames Epoch_ms Local_X 2 29 1707 1163033200 8.695 2 30 1707 1163033300 7.957 2 31 1707 1163033400 7.335 What I'm trying to do here is to take previously filtered data points like this and plug it into another csv file using csvwrite. However, csvread will only take in the Epoch_ms in double precision, storing the value as 1.1630e+09, which is sufficient for reading, as it does maintain
