A short companion for List Converter: when it is useful, what it expects, and what to check before using the result.
What it does
Turn a list into the shape you need: one item per line, comma-separated, a JSON array, a SQL IN clause or a numbered list. Useful for turning a column pasted out of a spreadsheet into something a query or a script will accept.
Use the tool
Open List Converter, add the input the tool asks for, run it, and check the output before using it elsewhere.
Input and output
- Input: text.
- Output: text.
- Category: Formats.
Privacy and processing
Processing happens locally in your browser. This tool does not upload the input to ilham.dev.
Questions
Does it deduplicate or sort?
Only if you ask it to. By default the order and the duplicates are exactly as you pasted them.
Why is my SQL IN clause broken?
Almost always because an item contained a single quote. The tool escapes what it can, but read the output before running it.
