XML Schema language is also referred to as XML Schema Definition (XSD).XML helps out in electronically sharing structured data via the public Internet or through a corporate network.The XML standard is a flexible & easy way to create information formats.XML Simplifies tasks like data transport, data sharing, data availability & platform changes.Usually, most of the XML applications work as expected even if you add new data (or it is removed).XML is just a piece of information wrapped in tags, just like the above-mentioned note.XML File type & structure appears as below mentioned: The maximum amount of columns in XLS format is limited to 256, whereas XLSX format allows more columns, but is not fully supported by all spreadsheet applications.Excel functions, formula, charts, formatting creating excel dashboard & others However, if you need your data with nice formatting and maybe some statistical formulas, you should export XLS or XLSX format. If you are planning to import the data to some other database, CSV is probably the best, as it is simple, straightforward, and requires no third-party libraries. So whenever you need to get your Django project data to some spreadsheet application, there are several ways to do that. Ws.column_dimensions.width = columnsĮxport_xlsx.short_description = u"Export XLSX" Response = 'attachment filename=mymodel.xlsx'Ĭ = ws.cell(row=row_num + 1, column=col_num + 1) Response = HttpResponse(content_type='application/') def export_xlsx(modeladmin, request, queryset):įrom openpyxl.cell import get_column_letter This format is great when you need more than 256 columns and text formatting options. There is a python library openpyxl for reading and writing those files. OpenOffice 4.0, for example, can only read it. It is fully supported by Microsoft Office 2007 and newer versions. OOXML or OpenXML) is a zipped, XML-based file format developed by Microsoft. We'll do the same in the next format too. Here we created one worksheet, filled it with data, marked the first row in bold, and made the lines in the other cells wrapped. Ws.write(row_num, col_num, row, font_style)Įxport_xls.short_description = u"Export XLS"
Ws.write(row_num, col_num, columns, font_style) Response = 'attachment filename=mymodel.xls' Response = HttpResponse(content_type='application/ms-excel') def export_xls(modeladmin, request, queryset): Note, that this format allows to have only 256 columns. There is analogous library xlrd to read XLS files. We are going to use xlwt library to create a spreadsheet. XLS is the main spreadsheet format which holds data in worksheets, charts, and macros. Response.write(u'\ufeff'.encode('utf8')) # BOM (optional.Excel needs it to open UTF-8 file properly)Įxport_csv.short_description = u"Export CSV"Īs you can see, HttpResponse is a file-like object and we used it to write data to. Response = 'attachment filename=mymodel.csv' Response = HttpResponse(content_type='text/csv') def export_csv(modeladmin, request, queryset):įrom import smart_str It's a textual format which one could easily create or parse himself, but there is also a python built-in library csv for handy data manipulation. Now let's create functions for each of those actions! Comma-Separated Values FormatĬSV is the most common import and export format for spreadsheets and databases. # admin.pyĪctions = Ī(MyModel, MyModelAdmin) In the admininstration options, we'll define three admin actions: export_csv, export_xls, and export_xlsx.
# models.pyĭescription = models.TextField(blank=True) It's a simple model with title, description, and - of course - the id. I will cover the mostly used formats: Comma Separated Values (CSV), Binary Excel (XLS), and Office Open XML (XLSX).įirst of all, have a look at the model we will be dealing with.
#Excel import xml or csv how to
In this post I will show you how to create admin actions which export selected items as files for a spreadsheet application (like MS Excel, OpenOffice Calc, LibreOffice Calc, Gnumeric, or Numbers). For example, you want to create some diagrams in Office program for a presentation. There are times, when you need to export the data from your database to different formats.
