A PlainSift practical guide
Turn an Excel column into a comma-separated list
Join spreadsheet values for a search field, tag list, or other simple comma-delimited input.
When another application expects “red, green, blue” but your spreadsheet stores one value per row, you need a delimiter join. Copy only the values from one Excel or Google Sheets column, then join the lines using a comma and a space. No formula or file upload is needed for a simple list.
First check what the destination accepts. A comma-separated search field is often just plain text; a CSV import is a structured file format. This guide produces the former. Values containing commas, quotes, or embedded line breaks need special attention before you treat the output as an import file.

Step-by-step instructions
These steps use the default options shown in each tool. Add changes in the order listed.
Trim lines
Open Trim lines and paste the copied column without its header. Keep both-edge trimming to remove spaces around each value.
Remove empty lines
Add Remove empty lines so blank spreadsheet rows do not turn into empty comma-separated entries.
Lines to a delimited list
Add Lines to a delimited list. Keep the comma delimiter and following space, then run the pipeline.

red, green, blueThe first two steps clean the copied values. The final step places a comma and one space between the three remaining lines.
Choose the separator your destination expects
Some fields require commas without spaces. In that case, turn off the following-space option on the final step. Other destinations accept semicolons, tabs, or a custom delimiter. Change only the separator; the tool does not infer a format from the text or insert quotation marks around values.
Duplicates remain unless you explicitly add Remove duplicate lines before the join. That is useful when repeated values are intentional. If you are creating a unique tag list, insert duplicate removal before conversion, while each value still occupies its own line.
A delimiter join is not CSV serialization
Consider two values: “Paris, France” and “Berlin, Germany”. Joining them with commas produces four comma-separated fragments, even though there were only two original values. PlainSift shows a note when a value already contains the selected delimiter, but it does not quote or escape the value for you.
For a real CSV import, use the spreadsheet’s CSV export and check the target application’s import settings. If the destination accepts JSON instead, a JSON string array preserves embedded commas and quotes without ambiguous item boundaries.
Common questions
Can I turn the comma-separated text back into rows?
Yes, use Delimited list to lines for simple literal-delimited text. It cannot recover the original boundaries if an item itself contained a comma, and quote marks do not protect embedded delimiters.
Why is there a line break at the end of my result?
When copied input ends with a line terminator, the join preserves a final LF. It does not insert another comma or an additional item for that final terminator.
