How to use Print a Hex Sequence
- 1. Set the Start value. This is a generator, so begin with Start (hex), the first number in the run. It accepts any hex value, letting sequences begin at 0, at ff00, or wherever your range lives.
- 2. Choose How many and Step. How many controls the count of values produced, and Step is the hex distance between neighbors. A step of 1 counts every value, while 4 or 10 walks word or paragraph boundaries.
- 3. Pick a Direction. Direction switches between Increasing and Decreasing. Counting down is handy for enumerating addresses from the top of a region backwards, without computing the endpoint yourself.
- 4. Copy the sequence. The values arrive one per line in the output pane. Copy them into a spreadsheet column, a test loop or a lookup table skeleton, and regenerate with new settings as ranges change.
When to use Print a Hex Sequence
Print a Hex Sequence emits a run of evenly spaced hexadecimal numbers from any starting point, rising or falling. Whenever you catch yourself typing consecutive hex values by hand, addresses, IDs, offsets, this generator produces the exact series instantly and without the inevitable typo halfway through.
- Enumerating register addresses. A peripheral has sixteen registers starting at 0x4000 spaced 4 apart. Generate the sequence and paste it beside the register names to draft the memory map table in your docs.
- Creating loop expectations for tests. A unit test checks that an allocator hands out sequential hex handles. Generating the expected series with the right start and step gives you the assertion list without arithmetic mistakes.
- Labeling rows in a binary layout diagram. A file-format diagram needs offset labels every 0x10 bytes down the margin. A decreasing or increasing sequence at step 10 supplies all the labels ready to paste into the figure.
- Filling a spreadsheet with hex keys. Spreadsheets can autofill decimal but not hex. Generate 200 sequential hex IDs here and paste the column straight in, skipping any conversion formulas.

About the Print a Hex Sequence tool
Print a Hex Sequence runs as plain JavaScript in your browser tab, with no server behind it. Generate increasing or decreasing hex numbers. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Hex Tools section, 108 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 4 settings, including Start (hex), How many, Step and Direction, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
