使い方
使い方
- Paste a list up to 100,000 characters and choose its literal separator.
- Choose comparison, sorting, and result display rules.
- Count the items, review the frequency summary, then copy it or download a text file.
Explicit matching and tie rules
Optional trimming happens before empty-item removal and comparison. Case-insensitive mode uses Unicode lowercasing for the comparison key but preserves the first encountered spelling as the result label. Frequency ties retain first appearance order.
Three orders and three formats
Sort by frequency, English alphabetical order, or first appearance. Show counts alone, counts with percentages, or counts as fractions of the analyzed total. Control characters in labels are escaped so every result stays on one line. Input is limited to 50,000 items, 20,000 unique items, and 500,000 output characters.
よくある質問
あわせて知りたいこと
Does case-insensitive mode change my labels to lowercase?
No. It combines values using Unicode lowercasing, then displays the spelling from the first matching item.
What happens when two items have the same count?
Frequency order keeps whichever item first appeared in the input ahead of the other tied item.
Does the custom separator use a regular expression?
No. It is matched as one to 20 literal characters, so characters such as dots, brackets, and plus signs have no special meaning.
