Frequently asked questions

What does Strip ANSI color codes do?

Remove terminal ANSI escape sequences to get clean, readable log text. Paste the text or drop the file; nothing leaves the page either way.

When would I actually use this?

Getting usable data out of something that was never meant to be parsed: pulling every address out of a pasted thread, turning a column of lines into a JSON array or an SQL IN clause, renaming a hundred identifiers from snake_case to camelCase in one pass.

What is the most common mistake?

Trusting an extraction to be exhaustive. A pattern that catches every address in the sample will still miss the one wrapped across a line break, the one written with a display name, and the one an email client turned into a link — count what came out against what you expected before you use the list.

How is Strip ANSI color codes different from Strip HTML tags?

They sit next to each other but answer different questions: Strip HTML tags is the one to open when you need it to remove all HTML tags from a snippet and keep just the plain text. Pick whichever matches what you're starting from — both are free.

Where do the figures come from?

Extraction runs on patterns, not on a parser: it recognises the common shapes of an address, a URL or an IP rather than validating them against their specification. That is the right trade for a paste, and the wrong one for input you are about to store.

How-toHEX vs RGB: How to Read and Convert ColoursHEX and RGB are two notations for the same colours. Here's how to read each, convert between them, and add transparency.ExplainerGradients, Banding, and Why the Middle Looks MuddyInterpolating in sRGB averages gamma-encoded numbers, so the midpoint of red to green is #808000 when the half-light answer is #bcbc00 — 57.2% too little light. Banding is a separate arithmetic problem: 8 bits give 256 steps, and a dark gradient may have only 28 of them. Here is both, computed.ExplainerColour Schemes Are Geometry on a Wheel — and the Wheel Is WrongComplementary, triadic, analogous and split-complementary are just rotations: add 180°, 120°, 30° or 150° to a hue. The arithmetic is trivial. The problem is that the HSL hue circle is not perceptually uniform — yellow and blue at the same HSL lightness differ in luminance by 12.85 times — so a generated palette has to be contrast-checked afterwards.ExplainerContrast Ratio: How WCAG Actually Computes ItThe WCAG ratio is (L1 + 0.05) ÷ (L2 + 0.05), and L is relative luminance, not brightness. Green carries 71.52% of it and blue 7.22%, which is why pure blue on white passes at 8.59:1 while mid grey fails at 3.95:1.
