XLSM is a macro-enabled spreadsheet containing cells arranged by rows and columns as well as embedded macros programmed in the Visual Basic for Applications (VBA) language. XLSM doesn’t take up as much disc space as XLSX and uses an open file format that can be used with many other applications. Whereas a CSV (comma-separated values) file is a text file in which information is separated by commas, and CSV files are most commonly encountered in spreadsheets and databases. Therefore, in this article, we are going to discuss the details of how to convert XLSM to CSV using Python.

Excel Conversion API

Convert XLSM to CSV in Python

Please follow the instructions specified below to convert XLSM to CSV using a Python code snippet. Please note that first, we are going to upload the XLSM to cloud storage, load the XLSM from the same cloud storage, and render the output in CSV format.

  • Create an object of CellsApi using client credentials
  • Now specify the name of input XLSM, resultant file name, and output format as CSV
  • Call cells_workbook_get_workbook(…) method to convert XLSM to CSV format and save the output to Cloud storage

Excel to CSV using cURL Commands

In this section, lets dsicuss the convesion of Excel to CSV using cURL commands. The pre-requisite is creation of JWT access token using following command:

-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Now that we have the JWT token, lets execute the following command to convert XLSM to CSV and save the resultant output in cloud storage.
