Batch Unix Timestamp Converter

Paste a column of timestamps to turn logs or exports into a table of dates. Each line can use a different unit.

Timestamps, one per line

Free to use. Your input stays in this browser.

How to use it

  1. Paste one integer timestamp per line.
  2. Choose an output time zone and select Convert.
  3. Review the marked lines, then copy or download the valid results as CSV.

Line numbers match the original input, including skipped blank lines. The CSV keeps valid rows in input order and includes UTC, the selected time zone, and an ISO date with the original fractional precision.
