Description:

Collapses a list of values by replacing serially incrementing sections with their range boundaries.

The result is a comma-separated list of ranges and individual values. The list separator and the range placeholder can be easily modified or defined as additional function parameters.

Values are compared in the order they appear in the list. For best results, the list should be sorted in ascending order.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
