Practical guide
How to use Line Processor
Line Processor performs repeatable operations on lists, copied columns, URL sets, keywords, and other one-item-per-line data. Operations include trimming, blank removal, deduplication, sorting, reversing, numbering, prefixes, and suffixes.
Step by step
- Paste one item per line.
- Choose an operation and any case or prefix option.
- Process the list, review the count, and move the result back to input if another operation is needed.
Example
pear
Apple
pear
bananaDeduplicated and sorted: Apple
banana
pearHow it works
Each action transforms an in-memory array of lines. Deduplication tracks previously seen values, while sorting uses locale-aware comparison with numeric handling.
Important limitations
- Operations are applied one at a time; their order can change the final result.
- Case-insensitive deduplication keeps the first spelling encountered.
Real workflows
When this tool is useful
Keyword and URL lists
Trim, deduplicate, and sort copied lists before importing them into a spreadsheet, campaign, allowlist, or review document.
Batch command preparation
Add a controlled prefix or suffix to every line, then inspect the result before using it as input to another tool.
Data reconciliation
Normalize casing and empty rows to compare two one-item-per-line exports without writing a temporary script.
Review the result
What to check before using the output
Operation order changes the answer. For example, case-sensitive deduplication before lowercasing keeps entries that would collapse if the same actions were reversed.
- Choose operation order before starting.
- Confirm case-sensitive behavior.
- Preserve a copy of the source list.
- Spot-check the first and last results.
Choose the right method
When another tool is better
Use a spreadsheet or data-processing language for multi-column records, quoted CSV, relational joins, or transformations that must be repeated and audited as one pipeline.
Privacy and browser behavior
Lists never need to be uploaded to 77 Toolkit, but copied exports may contain email addresses, private URLs, or account IDs. Replace sensitive values before sharing output.
Frequently asked questions
How do I trim, deduplicate, and sort together?
Run Trim, use the result as input, then run Remove duplicates and Sort in the order you prefer.
Are blank lines considered duplicates?
Yes during deduplication. Use Remove empty lines when you want none in the final list.
