What is UPPERFLATCASE?
UPPERFLATCASE is a text format where all spaces are removed and all letters are uppercase. It creates a continuous, compact string in all capital letters, often used for hash identifiers, compact constants, and situations requiring uppercase without separators.

- Hash Identifiers: Unique identifiers in compact format
- License Keys: Product keys and activation codes
- Transaction IDs: Short, readable transaction references
- Compact Constants: When underscores aren't allowed
- Barcode Text: Human-readable barcode identifiers
- Reference Codes: Ticket numbers, order IDs
