FAQ
What does this text checker do?
It generates a compact report with word/character counts plus common formatting warnings (double spaces, tabs, trailing whitespace, mixed line endings, invisible characters).
Is the sentence count accurate?
It’s an approximation based on punctuation, so it may miscount abbreviations or unusual formatting.
Does my text get uploaded to a server?
No. The checks run locally in your browser and the tool does not make network requests.
What are “invisible characters” and why do they matter?
Characters like zero-width spaces, BOM, or NBSP can break matching, sorting, or formatting even though they’re hard to see.
How do I check against a limit (e.g., a form field)?
Set “Max characters” and/or “Max words” and the report will flag when your text exceeds the limit.
Can I use this to fix the text automatically?
This tool focuses on detection and reporting; for cleaning/normalizing text, use the linked formatter tools.
Why do mixed line endings matter?
LF vs CRLF differences can cause noisy diffs and inconsistent behavior across editors; the checker warns when multiple styles appear in the same text.
