How to use CSV Group Text Aggregator

Build a reviewable list field per observed group while preserving the first-seen group order and selected source-value order. The output separately counts all source records and the values actually included in each joined text.

  1. Enter input, group columns json (empty array for one group), one text column as json array, literal join separator.
  2. Choose the settings for csv group text aggregator, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 5000 records,1000 observed groups,20 separator characters and 300,000 joined text characters before allocation.
  • Text is never evaluated or numerically aggregated. Joined text is not a reversible container when values contain the separator; source counts and exact policies remain explicit.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Does unique reorder my labels?

No. It keeps the first exact occurrence of each value within each group, then joins those retained values in source order.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
