A lot of cleanup work starts as one item per line and needs to become a comma-separated list, quoted list, JSON-ish array, or SQL IN clause.

The Line Comma Formatter tool handles the repetitive part so I can focus on checking whether the result makes sense.

The simple idea

A lot of cleanup work starts as one item per line and needs to become a comma-separated list, quoted list, JSON-ish array, or SQL IN clause.

I still treat the output as something to review, especially when it affects money, dates, privacy, or production data.

Step 1: Paste the one-item-per-line list

Step 2: Trim empty lines and extra spaces

Step 3: Choose whether each item needs quotes

Step 4: Choose the separator, usually a comma

Choose the separator, usually a comma.

Step 5: Pick the target shape such as array or SQL IN list

Step 6: Review the first and last item for extra commas

Step 7: Escape quotes if the output will go into SQL or code

My checklist

Before I trust the result, I check:

  • Paste the one-item-per-line list.
  • Trim empty lines and extra spaces.
  • Choose whether each item needs quotes.
  • Choose the separator, usually a comma.
  • Pick the target shape such as array or SQL IN list.
  • Review the first and last item for extra commas.
  • Escape quotes if the output will go into SQL or code.

A small tool is most useful when it makes the work visible and easy to verify.
