사용 방법
Write one line containing a number, such as aaa001@bbb.ccc. Every run of digits is detected for you.
Click a number to pick it. With several numbers (say aaa02@bb1295.c23123) you can pick more than one, and anything you leave unpicked is untouched. A zero-padded number is picked by default — padding usually means "this is the counter".
Each picked number gets its own row: start, step (1, 5, or −1 to count down), and zero padding. The line count and separator are set once for the whole list.
Hit "Copy all", click a cell in Google Sheets or Excel, and press Ctrl/⌘+V. Newline-separated fills a column; tab-separated fills a row.
자주 묻는 질문
Do leading zeros survive?
Yes. The width of the number in your template is kept, so 001 runs through 099 and 100 as three digits and grows naturally when it overflows (999 → 1000). Turn off "Pad with zeros" to get plain 1, 2, 3.
What if the text contains several numbers?
They are all shown as chips and you can pick **as many as you like, each counting at its own pace**. In aaa02@bb1295.c23123 you could step 02 by one and 1295 by ten while 23123 stays put. Anything unpicked never changes. A zero-padded number is picked by default.
Can it count down?
Yes. Enter a negative step such as −1 and you get 100, 99, 98… Use 5 to skip in fives.
How do I paste it all into Google Sheets at once?
Leave the separator on "New line", copy everything, click the first cell, and press Ctrl/⌘+V — it fills straight down. Switch the separator to "Tab" to fill across instead.
How many lines can it make?
Up to 10,000 at a time. Beyond that the browser starts to struggle, so it is capped.
Is anything sent to a server?
No. The whole list is built inside your browser. What you type never leaves your device and disappears when you close the page.
