FAQ
4 questionsDoes this tool upload my data?
No. It runs entirely in your browser using JavaScript. Your CSV data is never sent to a server.
Can I use regular expressions?
Yes. Toggle the 'Use regex' option to search with regular expression patterns.
Does this search the header row too?
By default, only data cells are searched. The header row is preserved as-is.
Can I delete values by replacing with nothing?
Yes. Leave the 'Replace with' field empty to delete all matches.
