Create a Date Vector

Create a Date Vector takes multiple YYYY-MM-DD dates and formats them into a single vector-style output. It’s a quick way to compress a list of dates into a clean, customizable string for use in datasets, code arrays, or time-based input formats.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .csv
Total characters: 0
Options
Pad single digits with zero
Use dash separator
Wrap in brackets

How to Use:

  1. Enter one date per line in YYYY-MM-DD format into the input box.
  2. The vector output updates live in the right box.
  3. Use the Options panel to format the output:
    • Add padding to single-digit months/days
    • Toggle between dash or compact format
    • Choose to wrap the final output in square brackets
  4. Use Choose File to load a .txt or .csv list of dates.
  5. Click Copy Output or Export to File to save your vector.
  6. Use Clear All to reset everything and start over.

What Create a Date Vector can do:

  • Combines multiple dates into a single, comma-separated list.
  • Filters out invalid formats or out-of-range values.
  • Automatically highlights output changes.

Tool Options:

  • Pad single digits with zero: Ensures consistent formatting (e.g., 2025-6-1 → 2025-06-01)
  • Use dash separator: Switch between YYYY-MM-DD and YYYYMMDD
  • Wrap in brackets: Formats the output as [2025-06-01, 2025-12-31]

Example:

Input:

2025-6-1
2025-12-31

With all toggles enabled, returns:

[2025-06-01, 2025-12-31]

With dashes disabled and wrapping off:

20250601, 20251231

Common Use Cases:

Create a Date Vector is perfect for developers formatting arrays, analysts preparing datasets, or anyone needing to organize lists of dates in a compact, standardized format. It’s especially useful for scripting, data pipelines, and batch-processing configurations.
