Format Details
CSV
CSV (Comma-Separated Values) is a plain-text tabular data format that uses commas to delimit column values and line breaks to separate rows. It is one of the most universally supported data interchange formats, readable by any spreadsheet application, database, or programming language. CSV is ideal for exporting and importing data between different systems due to its simplicity, human readability, and near-universal compatibility.
dataICS
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.
otherConverting CSV to ICS: what actually changes
CSV to ICS 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 .CSV and .ICS each hold
.CSV is a data format built for analysing, importing or exchanging records, storing rows, columns and value types. .ICS is a other format built for opening the file in the software that produced it, storing the internal structure of the file. Converting between them is a decision about which of those two jobs the result needs to do.
What changes when categories differ
The records in the .CSV file are re-encoded as a other for opening the file in the software that produced it. Values and structure carry over, but anything that is purely a data concept — column types, delimiters, nesting — has to be expressed in the new format's terms.
When this conversion is the right one
Reach for .ICS when you need a file for opening the file in the software that produced it, starting from analysing, importing or exchanging records. If that is not what you are after, check what else .CSV converts to before committing to this target.
Tips for a clean CSV to ICS conversion
Start from the original file
Convert the .CSV you started with, not an earlier .ICS output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Text/csv becomes text/calendar. 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.
Confirm the structure first
Open the .CSV briefly and check delimiters, headers and encoding. A misplaced separator or a stray quote is the usual reason the output looks wrong even though the conversion succeeded.
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 data files, split or compress the source first.
