What are list tools?
List tools process newline-separated or delimited text — the kind of data you copy out of a spreadsheet, CMS export, email, or any plain-text source. They perform common operations that would otherwise require a spreadsheet formula or a script: sorting alphabetically, removing duplicates, randomising order, merging two lists, comparing what's in both, and splitting text into structured lines. All processing happens in your browser — paste your list, transform it, copy the result.
Common uses for list tools
List tools are most useful when you have raw text data and need to clean, sort, or analyse it quickly:
- Sorting a list of names, URLs, tags, or items alphabetically before pasting into a document
- Removing duplicate lines from exported data, email lists, keyword lists, or log outputs
- Randomising the order of a list for fair assignment, raffle draws, or shuffled presentation
- Comparing two lists to find overlapping items, unique entries, or differences — without a spreadsheet
- Merging multiple lists and deduplicating the combined result in one step
- Splitting a block of comma-separated or delimited text into a clean line-by-line list
