How to merge two Excel XLSX files together in Python

Excel spreadsheet merging. It’s not flashy or exciting, but it can be very important for productivity. So, Python users, we have two options, the easy way and the hard way. Obviously we are going to go the easy route, so it’s time to bust out an API. We’ll all be home in time for supper.

First off, we shall start the install for our client:

pip install cloudmersive-convert-api-client

When that’s finished, we write out the code that will create our API instance, then call the merge_document_xlsx_multi function.

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = 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 class
api_instance = cloudmersive_convert_api_client.MergeDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file1 = '/path/to/file' # file | First input file to perform the operation on.
input_file2 = '/path/to/file' # file | Second input file to perform the operation on.
input_file3 = '/path/to/file' # file | Third input file to perform the operation on. (optional)
input_file4 = '/path/to/file' # file | Fourth input file to perform the operation on. (optional)
input_file5 = '/path/to/file' # file | Fifth input file to perform the operation on. (optional)
input_file6 = '/path/to/file # file | Sixth input file to perform the operation on. (optional)
input_file7 = '/path/to/file' # file | Seventh input file to perform the operation on. (optional)
input_file8 = '/path/to/file' # file | Eighth input file to perform the operation on. (optional)
input_file9 = '/path/to/file' # file | Ninth input file to perform the operation on. (optional)
input_file10 = '/path/to/file' # file | Tenth input file to perform the operation on. (optional)
try:
# Merge Multple Excel XLSX Together
api_response = api_instance.merge_document_xlsx_multi(input_file1, input_file2, input_file3=input_file3, input_file4=input_file4, input_file5=input_file5, input_file6=input_file6, input_file7=input_file7, input_file8=input_file8, input_file9=input_file9, input_file10=input_file10)
pprint(api_response)
except ApiException as e:
print("Exception when calling MergeDocumentApi->merge_document_xlsx_multi: %s\n" % e)

As you can see, we may specify up to 10 individual XLSX files to be used for our merge. If you require more files than that, simply continue calling the function using the previous response as your input_file1 to preserve the order.
