Rejected

Ideas we decided against. One page per idea with the rationale — check here before proposing an idea; never re-argue a decided one. The recurring theme: the editor serves a casual platform, and anything pushing toward full Excel territory is out.

• URL import — fetch a remote CSV/JSON URL instead of uploading.
• Multi-sheet XLSX — import and merge multiple workbook sheets.

• Regex find & replace — regular-expression find and replace across cells.
• Row grouping — Excel-style outline grouping by column value.
• Conditional formatting — highlight cells based on value conditions.
• Cell validation rules — per-column validation such as "must be positive".
• Named checkpoints — named snapshots in the history stack.
• Row description — a per-row free-text note.
• Column freeze / pin — keep arbitrary columns visible while scrolling.
