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.

Each row is an iCalendar property found in your VEVENT data. Edit Mapping to set the column title in the exported html output; use Include to omit properties.

# ICS value Mapping Include
Provide valid iCalendar above to load output options.

Map each VCF field to a normalized table column. Use Include to choose output lines; Check all / Uncheck all sit under the mapping table.

# VCF Field Mapping Include
Provide input above to load mapping options.

Column names and types feed SQL generation (same rules as the CSV tool).

# Field Name Data Type Max Size Key Include Trim NULL empty
Provide input to load columns.

What this conversion is for

Built for cases where iCalendar is the authoring truth and HTML is the runtime or publish surface. You get web-ready fragments for CMS embeds or static previews.

From iCalendar to HTML in four moves

Paste iCalendar text or upload the calendar/contact file.

Scan VEVENT blocks, DTSTART/DTEND, and UID lines for obvious duplicates.

Use mapping or options on this page so each iCalendar field lands in the correct HTML shape.

Emit HTML fragments or tables for CMS or static previews.

Before you convert

  • Recurrence (RRULE) and timezone rules may simplify when flattened.
  • HTML output should be treated as a snapshot until the next source refresh.
  • Keep a copy of the original iCalendar as the audit trail after you ship HTML.

Choose the right output

When HTML is the right output

  • You are promoting iCalendar into HTML because the next hop names that format in its contract or runbook.
  • Downstream asked explicitly for HTML while editors still live in iCalendar.
  • You need a deterministic export for CI, legal, or partner review—not a live sync.
  • The receiving system has a documented HTML ingest path (template, parser, or app import).

When another format fits better

  • Data pipelines want JSON/CSV, not HTML fragments with presentation noise.
  • Signed PDFs or static reports beat HTML when layout must not change.
  • If only text values matter, CSV is smaller and easier to diff than HTML tables.
  • Avoid HTML when the downstream system strips tags and breaks your structure.

Suggested workflow
  1. Paste iCalendar content or upload a compatible file.
  2. Review detected columns, mappings, and optional limits before conversion.
  3. Convert to HTML, preview when the page supports it, then download the result.

iCalendar to HTML overview

iCalendar to HTML Converter Overview

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.

Input format notes

About iCalendar as the source

iCalendar is parsed as structured input for this page. Use complete rows, valid syntax, and consistent field names so the converter can preserve the important data when creating HTML.

Output format notes

About HTML as the output

HTML is generated from the parsed iCalendar data. Review the output before importing it into another system, especially when the destination expects strict columns, dates, or contact fields.

Conversion guide

How to Convert ICS to HTML?

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.
