Frequently Asked Questions
How do I add a prefix to every line?
Paste your text into the Prefix/Suffix Lines tool, type your prefix in the Prefix field, and click Apply. Every line will have the prefix prepended. Leave the Suffix field empty if you only need a prefix.
How do I wrap each line in quotes?
Set Prefix to a single quote (') and Suffix to a single quote ('). Each line becomes 'original line'. For double quotes, use " in both fields. This is the standard way to prepare a list for a SQL IN clause.
How do I add a suffix for SQL IN clauses?
Set Prefix to ' (single quote) and Suffix to ', (quote + comma). The result is 'item1', 'item2', 'item3', each on its own line. Paste into your SQL WHERE column IN (...) query.
How do I add a prefix only to non-empty lines?
Enable the Skip Blank Lines option. Lines that are empty or contain only whitespace are passed through unchanged. The prefix/suffix is applied only to lines with content.
How do I add different prefixes to odd and even lines?
The browser tool does not support alternating prefixes. Use awk instead: awk 'NR%2==1 { print "odd: " $0 } NR%2==0 { print "even: " $0 }' input.txt
