How to convert CSV to Excel XLSX Spreadsheet in Python

Converting between CSV format and XLSX can be a bit of a tricky thing to set up if you go about it in the normal manner. That’s why I suggest following this tutorial to get this accomplished in a fraction of the usual time. Let’s begin.

Our first order of business is to set up our API client via this command:

pip install cloudmersive-convert-api-client

After which we shall call our function for CSV to XLSX conversion, like so.

from __future__ import print_functionimport timeimport cloudmersive_convert_api_clientfrom import ApiExceptionfrom pprint import pprint# Configure API key authorization: Apikeyconfiguration = cloudmersive_convert_api_client.Configuration()configuration.api_key['Apikey'] = 'YOUR_API_KEY'# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed# configuration.api_key_prefix['Apikey'] = 'Bearer'# create an instance of the API classapi_instance = cloudmersive_convert_api_client.ConvertDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))input_file = '/path/to/file' # file | Input file to perform the operation on.try:# Convert CSV to Excel XLSX Spreadsheetapi_response = api_instance.convert_document_csv_to_xlsx(input_file)pprint(api_response)except ApiException as e:print("Exception when calling ConvertDocumentApi->convert_document_csv_to_xlsx: %s\n" % e)

Done! This is just a taste of what this library can do, so be sure to look at the documentation for a full breakdown of all the different types of conversion and file editing that can be achieved with simple API calls like this one.
