Format Details
ICS
ICS (iCalendar) is the standard calendar exchange format used by Google Calendar, Apple Calendar, Outlook, and most scheduling apps. It stores events with titles, times, locations, and descriptions as plain text. ICS files are easy to share and convert to JSON or CSV for spreadsheets and apps.
otherJSON
JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format derived from JavaScript object literal syntax. It natively supports objects, arrays, strings, numbers, booleans, and null, allowing it to represent arbitrarily nested data structures. JSON has become the universal standard for REST API responses, configuration files, and data interchange on the web, with native parsing support in virtually every programming language.
dataConverting ICS to JSON: what actually changes
ICS to JSON is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .ICS and .JSON each hold
.ICS is a other format built for opening the file in the software that produced it, storing the internal structure of the file. .JSON is a data format built for analysing, importing or exchanging records, storing rows, columns and value types. Converting between them is a decision about which of those two jobs the result needs to do.
What changes when categories differ
The file is parsed and its contents are written out as structured data for analysing, importing or exchanging records. Everything that could be extracted from the source lands in the output; formatting and styling that have no equivalent in .JSON are left behind.
When this conversion is the right one
Reach for .JSON when you need a file for analysing, importing or exchanging records, starting from opening the file in the software that produced it. If that is not what you are after, check what else .ICS converts to before committing to this target.
Tips for a clean ICS to JSON conversion
Start from the original file
Convert the .ICS you started with, not an earlier .JSON output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Text/calendar becomes application/json. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Keep the output next to the original
Save the .JSON file alongside the source rather than replacing it. Having both means you can try a different target later without hunting down the original again.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge other files, split or compress the source first.
