# Sheets: A Spreadsheet That Works as a Shared Data Source > Start from a query result, a workbook or a blank sheet and work together with familiar formulas. Then use your tables in AI Analyst, agents, automations and datasites. HTML version: https://supaboard.ai/product/sheets A spreadsheet that works as a shared data source. Start with a query result, import a workbook or create a blank sheet. Work together with familiar formulas, then use your tables in AI analysis, automations and datasites. ## From spreadsheet analysis to shared data One sheet, followed from the first rows to the tools that read it. ### Pick up where the query left off Choose “Save as booklet” to save a table from Query Bench, a dashboard or a conversation as a sheet, import a workbook, or start a blank one. Saved results are snapshots. You can edit the sheet, but changes in the original source won’t update it automatically. Starts from: [Query Bench](https://supaboard.ai/product/query-builder), [Dashboards](https://supaboard.ai/product/dashboards), [AI Analyst](https://supaboard.ai/product/ask-analysts). ### The formulas you already know Add the change column, total it, look a value up: 515 functions, from SUMIFS and XLOOKUP to QUERY and SPARKLINE. Edit together and see each other’s changes as they happen. - Import xlsx, xlsm, CSV or TSV; export xlsx, CSV or TSV - One shared version, with 30 days of history ### A data source the rest of Supaboard can use A sheet works like any connected source. Ask AI Analyst about it, give your agents access, or build a datasite on it, and they read the rows on your sheet. Used by: [AI Analyst](https://supaboard.ai/product/ask-analysts), [Agents](https://supaboard.ai/product/agents), [Datasites](https://supaboard.ai/product/datasites). ### Keep a workflow moving as rows change When a new row is added, email the right team and log it in another sheet. Automations can also find, add, update or delete rows. - Triggers: Booklet changed, New row in a Databook view - Actions: Add, Update, Delete and Find booklet rows Runs in: [Automations](https://supaboard.ai/product/automations). ## Where your sheet goes Use the same shared tables across your analysis and workflows. [Query Bench](https://supaboard.ai/product/query-builder) results go into [Sheets](https://supaboard.ai/product/sheets) with "Save as booklet". - [AI Analyst](https://supaboard.ai/product/ask-analysts): Ask about a sheet, like “Which plan grew fastest from August to September?”, and get the answer from its rows. - [Agents](https://supaboard.ai/product/agents): Give an agent access and it works from the rows you checked. - [Automations](https://supaboard.ai/product/automations): Start a workflow when a row is added or a sheet is edited, and let it add, update or find rows as it runs. - [Datasites](https://supaboard.ai/product/datasites): Use a query or a sheet as the data behind a datasite, and share it with a public link. ## Sheets, in detail | Feature | Detail | | --- | --- | | **Functions** | 515, including SUMIFS, XLOOKUP, QUERY and SPARKLINE.

You can edit the sheet, but changes in the original source won’t update it automatically. Save the result again for fresh numbers. ### What can use a sheet as a data source? AI Analyst, agents you give access to, automations and datasites. Every tab is stored as a database table in your workspace, so they read it like any other connection. ### Can an automation change a sheet? Yes. Automations can add, update, delete and find booklet rows, and start when a booklet changes or a new row appears. ### Can I open my Excel files? Yes.
