Free online functions: steps and checks

Remove Duplicate Data Lines for Free

Paste the data rows and remove repeated whole lines while retaining their first appearance. Review the resulting order before copying; lines with different spacing or content are not the same exact line.

Deduplicate CSV Rows as Text for Free

Supply CSV rows as pasted text to remove exact repeated lines from the block. Inspect the retained records carefully because this operation compares complete text lines rather than parsing fields or selecting column keys.

Keep Unique List Entries for Free

Paste a line-separated list and keep the first occurrence of each exact entry. Copy the reviewed unique output into your next step, using a column-aware cleaner instead when uniqueness depends on particular table fields.
