Easy, intuitive, but no repeat?

This tool helps me make a .csv into .ics, and pretty easy. But would love to have a repeat option, with end date or number of events, and that doesn’t seem possible in this version. Lastly, would be good to see if there are two adjacent appointments in the .csv with the same name, there is an option to combine them into one event. Again, overall, elegant and simple and is way faster than making them manually.

Developer Response
Full support for recurring events, including automatic detection, has now been implemented in version 1.6. Enjoy!

I took the risk to pay the high price, having come from the software dev world of date transfer and computer interfaces. I tried out the free version. Impressive UI, so easy to use. Great documentation. Saves so much time importing a schedules such my company’s sale periods, my garbage collection calendar, etc. If you have a lot of events to add to your calendar, you do it in Excel first as a simple table. Then just highlight the table and copy it to clipboard, alt-tab over to the calendar importer and press the button to automatically import the clipboard. It will give you a chance to pick the calendar you want to import to, to pick which items you want to be recurring. If you don’t want to import to your calendar, you can choose to import to a .ics calendar file for portability to import to another system. The initial import screen is a little tricky because it shows the mapping of your column headings with the internal data fields, and because I didn’t read the documentation I had to play around a bit to get it to auto map correctly. Use these column headings in your Excel table: Title, Start Date, End Date, Start Time, End Time, Duration, All Day, Alarms, Location. Valid values for these fields are simple, so see the doc. If you leave a field blank, it figures out how to deal with it. I.e. you don’t need an end date. All Day, you just enter y into the cell or leave it blank. The developer worked extremely hard to figure out innumerable varying possibilities of data imported and covered many of them intelligently so that what you think you should get, you usually get. That makes this very, very, low in bugs and design flaws. There is a mechanism to stamp all imported events with an import ID in the note on each event. If you make a mistake after importing 100 events, you just search for that import ID in your calendar and delete all 100 at once and try again. Really quality work. $17 was a risk. It’s super cheap for the time I’ve saved and given that it’s a lifetime product. This developer really cares about the user experience. So simple. So useful. If you’re less technical, get a little help. This will save you tons of time in the long run. Thank you, Developer(s)!

CORRUPTED? But works on CSV files

Does not work for me. It says Row 2 is faulty and does not have the correct number of columns. Can’t make it work. Update: Got it to work by converting .XLSX file to .TXT file, then it worked. Developer warned against hidden Tabs in an Excel file.

Developer Response
Although we were able to resolve the issue directly, here is a solution for other readers: If you receive this error message when pasting spreadsheet data from the clipboard, the copied data probably contains hidden tabs. In this case, it may help to export the data as a CSV file and then import this file into the app.

Every year I convert and import data for hundreds of events. I’ve been using data found online, but have to convert some times for daylight savings time. The online ICS converter doesn’t show errors; it either imports a mess or the data not at all. This app - even the free version - SHOWS ERRORS!! What I spent hours on yesterday took a few minutes today. THANK YOU!!

- If the app cannot automatically detect the header row with column titles in the import data, you can now specify it manually. - The automatic mapping of column titles to calendar fields has been improved and now supports more languages. - For imports without start and end times, you can now specify in the settings how these events should be imported.
