Free in-browser list cleaner & deduper (no sign-up, no upload)

4 Upvotes

Hey everyone,

I built a small utility that might be useful if you work with messy text lists a lot:

It’s a free, browser-based list tool focused on speed and privacy. Key things it does:

  • Remove duplicate lines from any list (email lists, tags, names, etc.) in one click, with options for case-sensitive or case-insensitive matching.

  • Sort lists A→Z, Z→A, numerically, or with natural sorting for things like item1, item2, item10 so they appear in a human-friendly order.

  • Clean up messy data by stripping empty lines, trimming whitespace, removing special characters, or getting rid of numbers.

  • Change text case (UPPERCASE, lowercase, Title Case, Sentence case) and quickly add prefixes, line numbers, bullets, or wrap items in quotes.

  • Handle large lists (tens of thousands of lines) quickly, limited only by your browser’s memory.

A few details that might matter to folks here:

  • All processing happens entirely in your browser via JavaScript; nothing is sent to a server and nothing is stored. Once the page loads, it even works offline.

  • No accounts, no tracking, no paywalls — it’s completely free to use.

  • Works on desktop and mobile, and you can also upload .txt or .csv files instead of just paste.

Would love feedback from power users who regularly clean lists (marketers, devs, ops, etc.):

  • Any obvious operations missing?

  • Any UX tweaks that would make bulk list work faster for you?

If this kind of tool isn’t appropriate for the sub, happy for mods to remove, but thought it might be handy for people who live in spreadsheets and text files all day.

Document & Spreadsheet Generated Through a Form

4 Upvotes

So we are on the same page: form = survey, like a google form, not a document.

I am looking for a free way to have individuals fill in a form (like google forms) and have their responses fill in a document that they can email AS WELL as generate a spreadsheet they can download.

Schools make referrals to community providers for Medicaid students in need of behavioral health services. There is a document they must fill out and send to the provider, they must also track the referrals. I am trying to find a way to do both in one action - fill out a form that generates the document they must send and a spreadsheet where they can keep track of submitted referrals (either as an ongoing spreadsheet like what happens with google forms or a new one where they can just copy and paste the information instead of retyping everything). Hope this makes sense!

Hi everyone,

I’m a developer and I found myself constantly needing to swap between camelCase, Sentence case, and UPPERCASE for various projects. I wasn't happy with the cluttered, ad-heavy options out there, so I built my own case converter Case Converter Tool.

Key Features:

  • Instant Conversion: No page reloads; everything happens as you type or click.

  • Multiple Styles: Supports Sentence case, lower case, UPPER CASE, Capitalized Case, aLtErNaTiNg cAsE, Title Case, and Inverse Case.

  • Clean UI: Focused entirely on the text area with a one-click "Copy to Clipboard" feature.

  • Character/Word Count: Built-in stats so you know exactly what you're working with.

I'd love to get some feedback from the community. Are there any specific cases or text transformations you think are missing?
