Text formatting

Formatting is the difference between text you can read and text you have to decode. The tools in this category add structure: a JSON formatter that pretty-prints and validates in one step, line numbering for code samples and transcripts, word wrap at a fixed column, tabs-to-spaces conversion, padding, thousands separators for long numbers, and a Markdown table generator that saves you from aligning pipes by hand.

They earn their keep in documentation and code review. Paste a minified API response into the JSON formatter and it becomes navigable; number the lines of a snippet before discussing it in a ticket; convert smart quotes to straight ones before they break a config file; merge or sort paragraphs when restructuring a draft.

Everything is processed on your device — API responses and internal documents never leave the browser, which makes these tools safe for work material. They are free, need no account, and each remembers your options between visits so a repeated task stays a two-click job.
