🔍 从文本中提取整数Extract Integers from Data

使用说明与常见问题How-to & FAQ

「从文本中提取整数」是什么？What is the Extract Integers from Data tool?

从任意文本中提取整数（含负数、千位逗号），按出现顺序列出。适合从日志、表格粘贴中捞数字，本地处理。Extract integers (including negatives and thousands commas) from arbitrary text, in order of appearance. Handy for pulling numbers from logs or pasted tables. Processed locally.

如何使用「从文本中提取整数」？How do I use the Extract Integers from Data tool?

在「从文本中提取整数」中，把内容粘贴或输入到上方输入框，按需设置「分隔」，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「price 1,234 and -5 pcs」，得到「1234 ⏎ -5」。Paste any text, such as a log or a copied table. Every integer in it, including negatives and numbers with thousands commas, is listed in order of appearance (price 1,234 and -5 pcs gives 1234 and -5); choose the "Separator" for the list and click "Copy result" to copy it.

结果精确吗？Are the results exact?

精确。所有整数都按大整数（BigInt）处理，不经过浮点，超过 2^53 的数（例如 9007199254740993）也不会被舍入；几千上万行也是线性处理。Yes. Every value is handled as a big integer (BigInt) with no floating-point step, so numbers above 2^53 such as 9007199254740993 are never rounded; thousands of lines are processed in linear time.

负号和连字符怎么区分？How are minus signs and hyphens told apart?

数字前的 -、−、－ 算负号（例如 a-12、Temp -3°C）；夹在两个数字之间的连字符算分隔符，所以日期 2026-10-20 得到 2026、10、20，范围 5-10 得到 5、10。A minus sign (hyphen, U+2212 or fullwidth) in front of a number is a minus sign (a-12, Temp -3°C). A hyphen between two digits is a separator, so the date 2026-10-20 gives 2026, 10, 20 and the range 5-10 gives 5, 10.

小数会怎样？What happens to decimals?

小数（例如 3.5、1.5.2）不是整数，会整段跳过，不会拆成 3 和 5；结果说明里会显示跳过了几个。全角数字（１２３）会按半角处理。Decimals such as 3.5 or 1.5.2 are not integers, so they are skipped whole instead of being split into 3 and 5; the info line shows how many were skipped. Fullwidth digits are read as normal digits.

1e3、0x10、1_000 这类写法呢？What about 1e3, 0x10 and 1_000?

科学计数（1e3、2.5E-3）和十六进制（0x10）不是普通整数写法，会整段跳过，不会拆成 1 和 3，结果说明里会显示跳过了几个；数字间的下划线是分组写法，1_000 读作 1000（与“整数分析”一致）。10x20 这样的尺寸写法按两个数 10、20 提取。Scientific notation (1e3, 2.5E-3) and hex (0x10) are not plain integers, so they are skipped whole instead of being split into 1 and 3, and the info line shows how many were skipped. Underscores between digits are digit grouping, so 1_000 reads as 1000 (as in Analyze Integers). A size such as 10x20 gives the two numbers 10 and 20.

有哪些选项可以调整？What options can I adjust?

「从文本中提取整数」的设置：「分隔」可选 每行一个、空格、逗号、分号（默认 每行一个）；可勾选：「千位逗号」。改动任一选项后结果会按新设置重新生成。Settings in the Extract Integers from Data — "Separator": One per line, Spaces, Commas, Semicolons (default One per line); tick boxes: "Thousands commas". Changing any option regenerates the result with the new setting.

「从文本中提取整数」免费吗？需要注册吗？Is the Extract Integers from Data free? Do I need an account?
