Apply a license key in IronXL for Python

The license key is a long string that ends with an expiry date. Please ensure this is copied correctly, with no spaces.

# Apply the license key to the IronXL library
# Replace 'YOUR_LICENSE_KEY' with your actual license key string
IronXL.License.Key = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050"

# Apply the license key to the IronXL library
# Replace 'YOUR_LICENSE_KEY' with your actual license key string
IronXL.License.Key = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050"

The most robust method of applying a license key is directly in your code, before the library is called.

# Set the license key for the IronXL library at the start of your program
# This helps to ensure that the library recognizes your license as soon as it is needed
IronXL.License.Key = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050"

IronXL.License.Key = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050"
