Fylla

Next-gen AI for Google Sheets. Set up your table with column headers and example rows. Leave the cells you want filled empty, then run Fylla — no prompts, no chat sidebar. AI completes the blanks from the structure you already have.

Only empty cells are written. Your existing data stays unchanged.

How it works

  1. Set up one table block: column headers and/or example rows (examples help; headers alone are often enough).
  2. Leave the cells you want completed blank (or add blank rows to extend).
  3. Click inside the table.
  4. Extensions → Fylla → Fill the gaps.

Unlike a chat sidebar, you do not describe the task in prose — your grid already shows it.

Your table is the instruction

No chat sidebar. Fylla reads headers, examples, and relationships across columns — not a paragraph of prompts.

Only fills blank cells

Never overwrites what you already entered. Review AI results on important data before production use.

One action after setup

Select your table and run Fylla. Set columns once, fill — no prompt tuning per task.

Less typing, no prompt wall

Fylla reduces long prompt writing: set up the table once, then one menu action fills blanks. That helps people who find chat-style AI tiring — motor fatigue, executive load, or non-native English — without leaving Google Sheets.

Fewer keystrokes after setup One menu action instead of crafting instructions.
