Convert Unix timestamps to UTC dates and the other way around.
10-digit seconds, 13-digit milliseconds, or 2026-08-20T00:00:00Z
Unix time is usually seconds. JavaScript Date.now() is milliseconds. A 13-digit value is almost certainly ms; 10 digits are seconds. The converter detects both.
UTC, so logs from servers and CDNs compare cleanly. Local timezone is also shown from your browser.
Pretty-print JSON for theme settings, API payloads and feed debugging.
Validate JSON and show a precise parse error if the document is invalid.
Percent-encode text for query parameters, including UTM values and product IDs.
Decode percent-encoded URLs and query values.
Define the store metrics that matter, run a simple reporting cadence, stay humble about attribution, and connect numbers to decisions — not to dashboards for their own sake.
A useful store dashboard is small: conversion, AOV, margin, CAC, contribution and fulfillment health. Vanity traffic and session counts do not run the P&L.
Headless splits the storefront from commerce APIs. It can be justified for custom UX and multi-channel, but cost and SEO complexity are real. When coupled wins.
