What Is Text Validator?
You're testing form input or batch-checking content against rules. Eyeballing 200 entries for length or character violations is impossible.
Paste your text, set rules, and get instant pass/fail with details.
If you're testing form validation, you replicate server rules in the browser. If you're QA-ing user input, you spot violations before storage. If you're auditing content batches, you catch outliers fast.
