Inconsistent casing makes grouping, sorting, and matching unreliable. Whether your data has 'ALICE', 'alice', and 'Alice' mixed together, Tabular normalizes everything to the format you need in seconds.
Problems it solves
- Mixed-case customer names from multiple sources
- Product category fields with inconsistent formatting
- Country and city names that need title case
- Status fields that need to be uppercase constants
- Email addresses that need to be lowercased for deduplication
Example
Title case applied to all text columns.
Before
| Name | Country | Status |
| ALICE SMITH | united states | active |
| bob jones | CANADA | PENDING |
After
| Name | Country | Status |
| Alice Smith | United States | Active |
| Bob Jones | Canada | Pending |
Frequently asked questions
What casing options are available?
You can choose UPPERCASE (all caps), lowercase (all small), or Title Case (first letter of each word capitalized).
Can I apply different casing to different columns?
Currently one casing style is applied per operation, but you can run the tool multiple times with different column selections.
Will it affect numbers or special characters?
No. Casing only affects alphabetic characters. Numbers, punctuation, and symbols are unchanged.
What happens to abbreviations in title case?
Title case capitalizes the first letter of every word. 'USA' would become 'Usa'. For abbreviations, use UPPERCASE mode instead.
Is this a Pro feature?
Yes. Casing normalization is available on Pro and Business plans.
