• (2021-07-30) Benjamin Buter Petersen: Google has disabled this application, so it cannot be used anymore. :-( Sad!
• (2020-03-27) Erol Fox: Dev site down & Google has blocked authentication so app is dead. Maybe should be removed from web store?
• (2019-08-11) Kent “KC” Grimes: Simple and (used to) work perfect. Some time later than May 2019, this error appears and makes the extension completely unusable. Posting this in hopes the developer sees it and can fix it; can't find a way to contact the developer. UiApp has been deprecated. Please use HtmlService instead. (line 248, file "Code", project "Calendar Duplicate Deletor")
• (2019-07-25) Miguel Sampaio: This great tool worked great but now it does not work any more, since there is a message "UiApp has been deprecated. Please use HtmlService instead. (line 248, file "Code", project "Calendar Duplicate Deletor")" Can you make it work again?
• (2019-02-05) Did exactly what it said and worked in the background! Happy to have found this app. Thanks!
• (2018-03-06) Tom Wade: Very easy and straightforward to use. Unfortunately it nuked my calendar aside from one or two random events, so I can't comment on effectiveness.
• (2018-01-08) Tom Nowak: Did what it said it would do - If you want to replace single events with recurring, just add extra text in the "description" section of the recurring event, and the app should delete the other event, even if they are identical in all other properties.
• (2017-11-22) Adam Omar: Works as stated.
• (2017-09-28) Terry Roberts: Sometimes it works, sometimes NOT.
• (2017-09-11) Nick Harris: I was apprehensive at first, but after trialing it out on a few weeks and then months, it worked fine. Saved me a lot of time and hassle.
• (2017-08-30) Julien: Worked perfectly well.
• (2017-08-19) Mark Halliday: Did what I needed, first time, no issues. Would have taken me hours manually to achieve what this little program did. Many thanks
• (2017-08-03) Jim C: Just not working.
• (2017-07-26) Jefferis Peterson: broken
• (2017-07-26) Wimberley Garden: broken goes into an authorization loop and never recovers
• (2017-07-13) Adam Gallagher: I doesn't do anything, and the links to the developers support and website are broken.
• (2017-06-14) Stephen Williams: This is a nifty little tool that I used to help cleanup my Google Calendar (due to synchronization issues with Outlook Calendar that I encountered). It did a pretty solid job of finding most of the duplicated items on my Google Calendar, and the user interface can't get any simpler. Sometimes a dialog with pop up warning that the process failed, but everything seemed to work fine -- regardless of the message (the duplicates were deleted in the time frame I gave the app). It's a little rough around the edges in that regard, but otherwise a solid app that I greatly appreciated! Saved me A LOT of time cleaning up my calendar.
• (2017-05-16) Peter Johansson: Worked perfectly!
• (2017-02-13) Harry Slaughter: Actually CREATED duplicates.
• (2016-12-12) Pete Iannetta: Keeps giving me an unexpected error, not very helpful
• (2016-09-23) Dave Holland: A conference schedule builder put about 20 duplicates in my calendar - this app removed them in a moment. Great!
• (2016-08-28) Eddie Wong: Does exactly what it made to do. Exaclty what i was looking for. Very good!
• (2016-06-15) Paul Newman: Worked Twice Tried today comes up with error
• (2016-05-01) Rodney Wallace: It works for a few minutes, but then once everything synchronizes, the duplicates are there again.
• (2016-04-13) Frank Versace: Just used it... works beautifully! THANK YOU!!
• (2016-04-07) Courtney: Thank you!
• (2016-02-17) Tamir Hoshmand: it works and very easy to use thanks guys :)
• (2016-02-12) Glenda S. McKinney: Worked perfectly for me first time. I get some duplicates, mostly of holidays, due to syncing my Outlook calendar with my Google calendar via Ogg. This app initially only offers to de-duplicate the current day, so be sure to change one or both of the dates. I set this to go from today to two years in the future. A few duplicates disappeared before my very eyes, which was very satisfying. When I looked at this week, however, I scowled as I saw two duplicates were still present. Then I realized that those dupes were earlier in the week, so I hadn't asked for them to be removed....
• (2016-02-11) Mahinda Samarakoon: 100% worked for me. thanks
• (2016-01-24) Mario Cipriano: gets error
• (2016-01-22) Boney Varghese: excellent App
• (2015-12-08) James Ratliff: Worked great! Many thanks.
• (2015-12-08) James Maltese: Worthless!!! Syncing with outlook duplicated 2 years worth of appointments and this app didn't delete a single one. Tried it several times under my email and calendar and no results.
• (2015-11-01) t blaha: Worked for me with no issues that I can see to date.
• (2015-10-16) Lee Kornblum: I imported by Outlook calendar and ended up with duplicates of repeat events. This program deleted hundreds of duplicates in a minute or so.
• (2015-09-10) Эдуард Стручков: It really works! Thanks!
• (2015-03-16) Sherrie Buckridge: Had hundreds of duplicate appointments in my google calendar, most of them birthdays that I wanted to get rid of. At first I got an error, but after contacting support, they told me to try a month at a time. Took a while as you have to open a new tab and re input the parameters each time; choose the calendar, dates from and to. But that is much easier than deleting one by one. I opened several at a time, changed all to the right calendar and copy and pasted the dates. When I did that it went pretty fast. Thanks!
• (2015-02-19) I honestly can't tell you that I hated the app because even though I purchased it twice, I never got to use it. I purchased it a couple of days ago and went through the installation process. Nothing seemed to work. I reached out to the developer and didn't hear back for a couple of days and only after pinging him again. After pinging him via email, Pradeep said, "Give me an hour. I am running errands." Three hours later I emailed yet again, to which he replied, "I cancelled your order. Try purchasing again. Sorry i got stuck with other things." I reordered and re-installed a second time and it still didn't work. After alerting Pradeep, he said, "Looks like you have an issue with chrome, we cannot fix it. We will refund your money."... and so he did. I felt abandoned. I asked for help with Chrome, not knowing what to do. Pradeep finally said "this problem is a weird state of chrome browser. We have 1 in 10000, we could never solve it." Of course, for $10 I don't expect personal hand holding, but given the slow response and the reality of my experience, 1-star is an appropriate rating because others are susceptible to the same situation and treatment, though I hope for better for them.
• (2015-02-14) David Pape: It was exactly what I needed and fixed my problem in no time. Easy to use and use again and again and again!
• (2015-01-14) David Seifried: Very helpful app and excellent service from Pradeep! Saved me a lot of time when I needed to remove a bunch of duplicate items from my calendar. Thanks!
• (2014-12-26) D Puorro: I really liked this app. It removed a lot of duplicates, but most of my issues surrounded re-occurring entries, which can not be removed by the app. The developer really seemed to try his best to resolve all of my issues. In the end, he had to throw in the towel and offered a refund. I'm giving it 5 stars for outstanding customer service.
• (2014-12-19) Shad Butler: Update 12/18/2014 - For several weeks now I have been getting an error when trying to use this application and my initial discussions with the staff did not resolve the issue. This is after it was working fine for a period of time. It now says it does not work with a proxy but I have made no network changes, rather the application just stopped working. --------- After working with Calendar Duplicate Deletor staff I was able to resolve most of my issues with this application. While there are some limitations it appears that many of them are restrictions due to the functionality available for Chrome apps and Google API calls.
• (2014-11-02) Fred Weber-Liel: Really good App and worth every cent. I did run in big trouble with a sync program and CDD solved my problem with 5 calendar and more then 5000 duplicates. Even better is the service from the developer: quick and friendly - best I've seen for a long time. Served me a lot of time and money...
• (2014-10-31) The Lorax: Excellent support! My initial attempts to download and run Chrome App failed. But within a few minutes of sending email asking for help, Pradeep instructed me to use their more reliable Windows version (rather than Chrome App version). Working very smoothly now. Used the Windows version to remove duplicates for a two-year period on my calendar and it worked perfectly! Thanks for the great program!
• (2014-10-30) I had problems with the app at first but had an instantaneous response to my help request and the problem was resolved immediately. Great responsiveness and my duplicates are gone!
• (2014-09-24) Cynthia Keenan: HORRIBLE!!!! I run it and it does nothing, it gives me a blank screen. And they say it is 100% refundable but there is no email to be found to contact them to request this refund. I'm angry because I got played!!!
• (2014-09-14) This app removed over 7000 duplicates from a calendar going back more than 17 years. Doing this manually would have been extremely tedious. I had a small issue so dropped Pradeep, the author, a line. I got a very rapid reply, a quick resolution to the issue, and even a follow-up email checking all was well. In summary, excellent software and excellent customer service.
• (2014-09-09) Michael Gore: This chap (Pradeep,) is amazing. The software saved me hours of time, and when I needed help (my fault), the response was immediate. Would have him in my company in a heart beat!
• (2014-09-05) Josh Even-chen: This app is very professional and did what I needed it to do. I had an issue with the sheer volume, which I couldn't resolve myself, so I contacted Pradeep, and I was amazed at the speed he replied and provided the antitode. Well done Pradeep. I too am a very happy and grateful customer.
• (2014-09-01) Amy: Great app, but I wish it could remove duplicates across multiple calendars. For example, I have 3 Google Calendars, all nested under "My Calendars": --1 calendar w/ events that were imported from my daughter's school --1 w/ events imported from my son's school, --& 1 w/ family events. Each is color-coded. When I print-out the master calendar, I can see who has events scheduled at a glance. The problem is that now I have duplicates & triplicates on my master calendar because some items, like holidays, appear on each sub-calendar. However, w/ this app, I can only remove duplicates within in one sub-calendar, but not across them. Still, it's a great app when you are working w/ a single calendar.
