Conversions run in your browser; structured data is flattened to a table when needed, then the same engines as /csv/* are applied.
ConversionTab date / time standard (ICS → table)
Calendar fields such as DTSTART, DTEND, DTSTAMP, CREATED, and LAST-MODIFIED are exported as ISO-like text (not raw Excel serials): for example 1997-07-14T17:00:00Z for UTC, 1997-07-14T17:00:00+05:30 for a fixed offset, 1997-07-14 for all-day style dates, or 1997-07-14T17:00:00 when the ICS value has no Z / zone. EXDATE / RDATE lists use commas between values in the same style.
If you edit the file elsewhere and later convert back to ICS (e.g. from Excel), use these same shapes in cells—or real Excel Date/Time cells—so start/end and timestamps map reliably. Locale-only strings (e.g. 14/07/1997 alone) are not guaranteed to parse.

Overview & guides
Transform iCalendar into HTML efficiently with our iCalendar to HTML Converter, perfect for web-friendly tables.
Designed for interactive data, it offers secure and accurate conversions, making dynamic web pages transformations effortless.
You can either paste your iCalendar data directly into the input field or upload a file. Choose HTML as the output format, and your converted file will be ready shortly.
The processed HTML output is available to copy or can be downloaded as a file by entering a desired file name.
Step 1: Input iCalendar Data:
Provide your ICS text on the Text tab or upload a file on the File tab via 'Drop/Browse File'. Click Load Sample to load the sample calendar.
Step 2: Mapping Columns:
Map iCalendar properties to the columns that will drive the generated HTML table.
Step 3: Include Desired Properties:
Use Include to choose which properties appear as table columns.
Step 4: Proceed with Conversion:
Click Convert to render HTML from your mapped data.
Step 5: Copy or Download HTML:
Copy the HTML from the output area or download it as an .html file.
Step 6: Date / time standard:
Calendar fields export as fixed ISO-like text (for example 1997-07-14T17:00:00Z for UTC, 1997-07-14 for date-only, or with ±HH:MM when the ICS used an offset). EXDATE / RDATE use comma-separated tokens in the same style. There is no per-column custom format picker—reuse this shape when preparing data for a round-trip back to ICS.
