Real capitals versus CSS text-transform
If the capitals are for a website, there are two different things you might want. Styling a heading with the CSS rule text-transform: uppercase leaves the underlying text in its original case, so search engines, screen readers and anyone copying the text still get the readable version. Converting the characters here changes the text itself, which is what you want for a spreadsheet cell, a printed label, a code constant or a platform that strips your styling.
Choose the CSS route for design, and this converter for data. Baking capitals into body copy you will later restyle is a decision you tend to regret, because the original casing is not recoverable — “NASA” and “nasa” look identical once everything is shouting.
Readability and accessibility of all caps
Long stretches of capitals are slower to read. Lower-case letters have ascenders and descenders that give each word a distinctive outline, and capitals flatten every word into the same rectangle, so the eye has to decode letter by letter. That cost is invisible in a three-word label and obvious in a paragraph, which is why style guides restrict all caps to short headings, labels and acronyms.
Some screen readers also read a fully capitalised word letter by letter when they cannot tell it from an acronym, so a capitalised sentence can be announced as a string of individual characters. If capitals are purely visual, use styling rather than changing the characters, and keep genuine uppercase text short.
