Frequently Asked Questions
How do I convert an Excel column to a comma list?
Simply select the cells in your Excel or Google Sheets column, copy them (Ctrl+C or Cmd+C), and paste into the input box. The tool automatically detects newlines between cells and converts them to commas, creating a horizontal comma-separated list.
Can I use this for SQL 'IN' clauses?
Yes! This is perfect for SQL queries. Paste your list of IDs, enable 'Wrap Items' and select 'Single Quotes (SQL)', and you'll get output like: 'ID1', 'ID2', 'ID3' ready to paste into your WHERE column IN (...) clause.
Does it handle empty cells?
Yes. The 'Remove Empty' option (enabled by default) filters out blank cells/lines to ensure your comma-separated list is clean. Uncheck this option if you want to preserve empty values.
Can I use delimiters other than commas?
Absolutely! You can choose from Commas (CSV), Semicolons, Pipes ( | ), Tabs (TSV), or enter a completely custom delimiter. The 'Add Space After' option controls spacing: ', ' vs ',' for better readability.
How do I remove duplicate values?
Enable the 'Remove Duplicates' checkbox in Advanced Options. The tool will automatically keep only unique values from your column, useful for creating distinct lists or cleaning data.
Can it sort the values alphabetically?
Yes! Use the 'Sort Order' dropdown to sort your values A → Z (ascending) or Z → A (descending) before converting to a comma-separated list.
What's the Wrap Items feature for?
Wrap Items adds characters around each value. Use 'Single Quotes (SQL)' for SQL IN clauses, 'Double Quotes' for JSON/CSV, or 'Brackets' for arrays. For example, wrapping with single quotes converts: ID1, ID2 → 'ID1', 'ID2'.
Is my spreadsheet data safe and private?
Yes, 100% safe. This tool runs entirely in your web browser using client-side JavaScript. Nothing you copy from Excel or Sheets is ever sent to our servers. All processing happens locally on your device.
Can I add prefix or suffix to each item?
Yes! Use the Prefix and Suffix fields in Advanced Options. For example, add prefix 'https://' to convert: example.com, test.com → https://example.com, https://test.com. Useful for batch URL creation or data formatting.
Can I see the changes before copying?
Yes! Click the 'Compare' button to enable side-by-side comparison mode. This shows your original column on the left and the comma-separated output on the right, making it easy to verify the conversion before using.
