HTTP Status Code ReferenceSearch and browse every standard HTTP status code by class, with its name and a one-line description.Morse code translatorTranslate text to Morse code and back. Letters, digits and punctuation round-trip exactly; a word gap is written “/”. Takes a whole file, so a long log does not have to go through the clipboard.ASCII Table ReferenceFull ASCII table (0-127) with a decimal / hex / octal / binary / character converter and a text-to-codes panel.QR Code GeneratorCreate a QR code from any text or URL — free.Number base converterConvert numbers between all 35 bases, exactly, with two's complement.Programming case converterConvert identifiers between camelCase, snake_case, kebab-case, PascalCase and CONSTANT_CASE, one per line. Runs of capitals split correctly: parseHTTPResponse becomes parse_http_response.Column extractorExtract a single column from delimited data (CSV, TSV…). Works on a pasted block or on a file you drop in.Regex testerTest a regular expression and see what it does: matches highlighted in the text, every capture group listed, a replace panel, and the pattern read back to you piece by piece. Flags are toggles that say what they change, and a pattern that could freeze the page is flagged before you run it.

Frequently asked questions

What is ASCII code converter?

Convert text to ASCII/Unicode code points and back.

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 ASCII code converter different from HTTP Status Code Reference?

They sit next to each other but answer different questions: HTTP Status Code Reference is the one to open when you need it to search and browse every standard HTTP status code by class, with its name and a one-line description. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Morse code translator is the closest one after this: Translate text to Morse code and back. Letters, digits and punctuation round-trip exactly; a word gap is written “/”. Takes a whole file, so a long log does not have to go through the clipboard.

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.
