  • (2023-10-12) Raul Calle: Exelente, gracias por esta maravillosa herramienta, me facilita mucho mi trabajo.
  • (2023-10-06) Thomas Exelby: Fantastic. Keyboards shortcuts very useful. Does not work on all ALL text forms however (some custom wordpress modules for example)
  • (2023-09-25) Jon Sorensen: I like it, but it always seems to inject a space after capitalised letters when changed for some reason, which is pretty annoying.
  • (2023-09-03) Melvin: Wow! Just wow!
  • (2023-08-17) Scotty Vorenberg: Works like a truck driver. I wish there were a version for Windows 11.
  • (2023-06-23) Josh G: works exactly as expected to quickly convert the case of words. I've used this for years, but never reviewed it. But now I'm reinstalling windows and needed to reinstall some extensions.
  • (2023-06-05) Radoslaw Jaszczak: works as expected
  • (2023-05-23) ConsultingSide Team: So simple but so useful for a repetitive tasks. Thank you Lorek for a brilliant extension!
  • (2023-05-05) Maria Atenas Rivera Velázquez: It capitalizes some articles sometimes in the middle of a sentence/title, unsure why. I keep having to manually replace the "the", other than that amazing lifesaving timesaving app! Thank you!
  • (2023-03-25) Surya Ravishankaran: Lifesaver and timesaver! Thank you
  • (2023-03-20) Nephtali Flores: Good extension but had to disabled it because for some reason when I try to type @ (at symbol) it doesn't work. Using Macbook Pro with spanish keyboard, MacOS (in english) + Chrome (in english). Hope they fix it.
  • (2023-03-02) Steven Parker: Love this extension and I use it daily. The only thing missing from it is a custom words dictionary because I have to keep changing acronyms and product names back.
  • (2023-02-21) EDPMS REGION VI: Coool!
  • (2023-02-14) Bee - Sharing (Mapa): Es excelente pero en Edge me desabilita el @ tengo que dejar de usarlo por eso.
  • (2023-02-07) Vincent Woodard: This is exactly what I was hoping for! Convertcase.net used to be my go-to, but I got tired of opening another browser to do it. Copy and paste, change the case, then copy and paste again. Thank you for making an extension that eliminates the extra steps and is easy to use.

  • (2022-05-16) Jorge Hoyos Rentería: It's a great extensión. One thing missing: It would be great to have a custom setting where you can override the "ignore list". Many times the text is already in all caps so if I want to change it to Title with the filter I made, the words in the ignore list will remain uppercase.
  • (2022-03-10) Yanike Mann: Incredible! Love it on Chrome OS.
  • (2022-03-03) Josh Lisciarelli: Easy to use and effective. Quick install with lots of change case options and the option to map custom keyboard commands makes this a MUST HAVE extension.
  • (2021-12-07) Daniel MORTALI: Doesn't work.
  • (2021-11-20) Gregory Allen Mansheim: Sentence Case results in a lower case i. "It's only necessary to capitalize other pronouns when they begin a sentence.

    Change Case no longer works for me on the latest Chrome version under Windows 11 Pro. It appears in the context menu (right click), but selecting an option (lowercase, UPPERCASE, whatever) doesn't do anything. Hot keys do not work either. It used to work.

  • (2022-11-28, v:2.4.2) Saber: Firefox?
    Can you please create the same extension for Firefox? I need something like change case where I can use a key bind to change the case of a text but I'm not finding anything with the same functionality on Firefox.

  • (2021-12-27, v:2.4.2) Gerardo Frausto: Hello
    I love your extension for making Title cases, but I have noticed that this is causing a bug on my keyboard on a Mac, now I am not allowed to use OPT + 2 = @ or OPT +3 = # etc... I am on a spanish keyboard, but I noticed only in this chrome session where I have this extension I have this failure. I deactived the extension and it started working again. I wonder you guys can fix it as this extension is very handy.
  • (2021-12-09, v:2.4.2) Guilherme Salomão: Can't use the extension with external links
    I use the Notion (www.notion.so) Windows app, that is basically a chrome app that opens in a separate window. But I can't use the Change Case extension in this app. The following error shows up: "Cannot access a chrome:// URL" And when I go to the extension settings and "Allow access do file URLs", the error changes to: "Cannot access contents of the page. Extension manifest must request permission to access the respective host." Is there anyway you could fix this?
  • (2021-09-22, v:2.4.2) Sina: Request for creating a combination of choices
    Dear Developer, Thanks for your excellent extension. I am using it for developing websites, and it is so helpful. The functions I am using the most are: "No case" to remove dash between words and then "Title Case". So, could you provide users with few options to make their combinations of functions? For example, I need a choice to make "No case" + "Title Case". Then I do not need to do them separately. I hope you can secure these features. Thank you
  • (2021-08-29, v:2.4.2) Robert Perez: Feature Request
    Could you an edible text box when you click the plugin but also have the ability to right click and change case? For example, some places on the browser don't let you change case, so I rather have a text box editor when I click on the plugin so I can copy and paste text there then change the case.
  • (2021-06-11, v:2.4.2) Sibin David: Site Access not displaying
    For some reason, the extension is asking for site access, but upon navigating to the extension settings, I found out that the drop down menu is not even showing up where I can select from the 3 usual options. Please help.
  • (2021-05-18, v:2.4.2) A9: Extra spaces are inserted
    Change case is inserting extra unwanted spaces. For example "cHANGE cASE" becomes "C hange c ase" when I select Sentence case.

  • (2020-05-23, v:2.4.2) John Navas: Incorrect Title Case
    Your Title Case incorrectly capitalizes "The" instead of "the". Articles (a, an, the) should be lowercase according to Chicago Manual of Style, AP Style, and NY Times Style. Please correct this. Thank you.

  • (2020-03-15, v:2.4.2) John Legg: Case Conversion
    Hi When I use Alt-3 to change selected text to Proper Case, it seems to duplicate some characters. For example, here is my source text: "Order Your Artila Electronics Controllers and Interfaces for Demanding Industrial Control and IoT Applications. All with Free UK and EU Shipping" When I select the text and enter Alt-3, I get: "Order Your Artila Electronics Controllers and Interfaces for Demanding Industrial Control and IoTT Applications. All with FreeUKk andEUu Shipping" I have the following set in the ignore list: UK,EU,PC,GPIB,PCI,IoT Maybe I am doing something wrong? Kind regards John Legg ([email protected])

  • (2019-07-01, v:2.4.1) Richard Hoefer: Dev — there is a weird thing happening when I click on this extension's OPTIONS — here is short screencast to show what I see
    To Developer: bartoszlorek.pl — Was very excited to try this extension since it is highest rated amongst various similar purpose extensions — but I am wondering if anyone else is seeing this very odd performance when clicking on the OPTIONS — this rapidly vibrating/jiggling display that seems most likely to be some conflict or error. I recorded this short screencast to display what I am seeing. The link goes to a video on my Google Photos cloud space: https://photos.app.goo.gl/BRrm16DSFUXTcVxR8 Anyone else seeing this?
  • (2019-05-31, v:2.4.1) Dwain Wilder: Access problem with ChangeCase
    On Chrome,ChangeCase does not appear in the drop-down menu, though it does in Firefox. So the only access I have is through the short-cuts. Is this a platform/OS problem? I'm running Chrome 74.0.3729.169 under Mac OS 0.12.6 (16G2016) on a MacBook 2.4 GHz Intel Core 2 Duo. Thanks for any advice! Love this tool on Firefox!
  • (2019-03-05, v:2.3.0) Michael Day: Format phone number?
    Love the current change case implementation using shortcuts to invoke (eg alt-4 for sentence case). Another use case I have is to format phone numbers: with a variety of delimiters: • strip all delimiters • format with hyphen • format with space • format with dot
  • (2019-02-13, v:2.3.0) Nolan Donovan: "Correct List" logic for lower vs UPPER
    Suggestion: If there were a way to have the "Correct List" filter only convert for certain types of case conversions and not others, that would be awesome. ex: If I have "LLC" as a "Correct List" and press a hotkey to have it switch to lowercase, I would want LLC to become lower as well, BUT if I used Sentence case or Proper Cased, I would want it to stay as "LLC".
  • (2019-02-13, v:2.3.0) Nolan Donovan: "Correct List:" Changes Case From Middle of the Word
    Hey there, love the extension. One thing that is a nuisance though is that the option for "Correct List:" changes the case within the middle of a word. Example: working in web marketing, I have added "SEO", "PPC", "HTML" etc to the Correct List to convert, but things like "IP" or "API" would match with something in the middle of the word. If typing "Capital" and I want to make it lowercase, having "API" in the Correct List would switch it to "cAPItal". If the extension instead took my selection and replaced only things separated by word boundaries, that would be a big improvement for me.
  • (2019-02-12, v:2.3.0) Robert Sandoval: How Does This Feature Work?
    I can not seem to get the shorcut menu. I also can not seem to get the shortcut keys to work. My test was to paste into Gmail and Google Sheets.
  • (2018-11-07, v:2.3.0) Joakim Nystrom: @ character stopped working for keyboard with swedish layout.
    All of a sudden the at symbol stopped working and it gave me an error of some kind "can't switch to extension http://" (or similar) in a popup each time I tried to get an at-character. Combination in swedish keyboard is "alt + 2"
  • (2018-08-22, v:2.3.0) Jeff H: data:text/html, <html contenteditable>
    If you enter "data:text/html, <html contenteditable>" into the URL field you get a basic notepad. But whenever I try to change case on the text that I pasted into it I get the error message. "Cannont access contents of the page. Extension manifest must request permission to access the repetitive host."
