Which tool for the job?

My essay has a word limit → Word counter
Counts English words and Chinese characters; when a social platform limits characters instead, use the Character counter.
A list has duplicate names → Remove duplicate lines
Paste one name per line to de-duplicate, then tidy it with Sort lines.
Convert Simplified Chinese to Traditional → Chinese Traditional/Simplified converter
Common regional terms are converted too; still proofread names and proper nouns.
An API response is one unreadable line of JSON → JSON formatter
Formatting also points to the line with a syntax error; to open the data in Excel, use JSON to CSV.
Spot the differences between two texts → Text diff checker
Highlights added and removed lines — useful for contract clauses and config files.

FAQ

How are Chinese and English words counted?

Chinese is counted per character and English per word, with characters, lines and paragraphs shown too — handy for word limits on reports and submissions.
