      • Text Toolbox

      Text Toolbox is an integrated browser text utility that consolidates the most common cleanup, extraction, and formatting operations into a single page. Messy text from a webpage, lists of fields, or content that needs bulk reordering — all handled in a few clicks.

      What problems does it solve?

      • Extract specific content: pull URLs, JSON keys, pattern-matching fields from a large body of text
      • Clean up noise: strip ads, citation residue, HTML tags, blank lines
      • Tidy terminal-copied text: strip the quote bars and hard line wraps from Claude Code / terminal output and restore paste-ready paragraphs
      • Batch formatting: add prefixes/suffixes to each line — Markdown lists, CSV, SQL IN clauses
      • Normalize case: upper, lower, title case, sentence case
      • Sort & organize: asc/desc sort, reverse, dedup (with an exclusion list)
      • Complex pipelines: filter → regex → affix multi-step cleanups

      Page layout

      The page is a two-column layout. The main column carries the primary flow; the side rail holds the more specialized panels:

      Main column

      1. Source Text — input area + file upload + the "Smart Trim" toggle (bottom right)
      2. LINES — organize / filter / prefix-suffix rows, with parameter inputs inline
      3. CASE — the four case-conversion buttons
      4. Result pane (appears once there's output) — copy / export / format / move-to-source

      Side rail

      • REGEX — regex input + 4 presets + 3 flags + Run Match / Remove Matches / Batch Task Extract
      • FORMAT — Format, Smart Split, CLI Text Cleanup, JSON Beautify
      • LINKS — Common Link Replace, Weibo Link Convert, Custom Operation

      Line operations and case conversion are the highest-frequency actions, so they sit between input and result; regex, whole-text reflow, and link converters are more specialized and live in the rail so the result pane stays on screen.

      Source Text card

      • Paste: directly into the textarea
      • Upload: drag-and-drop or click; TXT, MD, JSON, CSV and other rich-text formats supported
      • Smart Trim toggle (default on): when on, almost every processing button first trims per-line whitespace and drops empty lines; when off, the original line structure is preserved

      REGEX panel (side rail)

      • Regex input: any JavaScript regex pattern
      • 4 common presets (CheckableTags): one click fills in the regex and sets the appropriate flags
        • URL (no params): matches plain https:// URLs without trailing punctuation
        • URL (loose): catches URLs containing brackets, semicolons, more punctuation cases
        • Remove Index: strips leading "1. ", "2、", "3) " line numbers
        • Extract JSON Key: pulls every key name out of a JSON blob (multiline)
      • 3 flags: global (g) / multiline (m) / case-insensitive (i)
      • Three buttons:
        • Run Match: extract every match and list them; toast shows the count
        • Remove Matches: delete matches from the source; also collapses 3+ newlines to 2
        • Batch Task Extract: a URL → number pairing pipeline — finds each line's URL, then scans for numbers attached to keywords like 点赞 / 转发 / 评论 / 播放 / 差 / 曝光 / 阅读 (Chinese social-media metrics) and outputs CSV grouped by metric

      LINES panel (main column)

      Organize

      • Sort Ascending / Descending: alphabetical (Unicode order); click toggles direction
      • Reverse: invert line order
      • Adjacent Swap: swap line pairs end-to-end (input must have an even line count; built for classification tasks where the number sits on the line above the link)
      • Dedup: drop fully duplicate lines
      • Exclude (the input on the same row): entries listed here are ignored by Dedup and persist locally. E.g. add Home and About to preserve those headings across repeated occurrences

      Filter

      • Type comma-separated keywords, e.g. ad,promo,channel
      • Click "Filter Lines": delete every line containing any of the keywords; result lands in the Result card

      Prefix / Suffix

      • Prefix input: prepended to every line (empty by default)
      • Suffix input: appended to every line (defaults to ,100, edit freely)
      • Regex Extract + Affix: the button on the right of the same row — extracts using the regex from the REGEX panel, then batch-applies prefix/suffix in one step
      • Example: prefix - , empty suffix → convert plain text into a Markdown list
      • Example: prefix ', suffix ', → convert a list of strings into a SQL IN (...) clause

      CASE panel (main column)

      Four buttons, applied line by line across the whole text:

      • UPPERCASE / lowercase
      • Title Case: capitalize the first letter of every word
      • Sentence case: capitalize the first letter of every sentence, lowercase the rest

      FORMAT panel (side rail)

      • Format: drop blank lines + smart trim (or not, depending on the toggle)
      • Smart Split: uses compromise English NLP for sentence boundaries + Chinese paragraph rules
      • CLI Text Cleanup: built for text copied out of Claude Code / a terminal — strips leading quote bars (▎ ▌ │) and indentation, reflows lines hard-wrapped at the terminal width back into full paragraphs (CJK lines join directly, Latin lines get a single space), and keeps list items and code blocks line-by-line. The result is auto-copied to the clipboard, ready to paste
      • JSON Beautify: lenient parse (handles unquoted keys, single quotes, comments) + 2-space indent
      • Common Link Replace: replace every https://huggingface.co with https://modelscope.cn/models — useful for switching HuggingFace links to a China-accessible mirror
      • Weibo Link Convert: batch-convert mobile Weibo (m.weibo.cn) links into PC weibo.com links plus the author's profile URL. Output is grouped into PC links / author profiles / unresolved; links carrying a uid resolve locally, detail pages need a network lookup for uid/bid, and each failure is annotated with its reason (no uid in link, uid/bid not found on the page, request failed)
      • Custom Operation: extract all URLs via the "URL (loose)" preset + reverse order + join with commas (handy for reverse-lookup URL lists)

      Result pane

      When something has been produced, the result pane surfaces:

      • Copy: one-click clipboard copy
      • Export: download as text-processed.txt
      • Format: clean up extra blank lines in the result
      • Result → Source: pipe the result back into the input for the next step (great for multi-stage pipelines)

      Tips

      Getting started

      • Try the presets first — REGEX panel in the side rail → click a tag
      • Test on a small slice before processing critical data
      • Stacked operations: filter → extract → affix solves most cleanups in three clicks

      Power moves

      • Keep Smart Trim on for almost every workflow
      • Chain multi-step pipelines via "Result → Source"
      • When regex stumps you, describe the problem + sample input + expected output to ChatGPT/Claude
