list-excel-tables

Read-only

List all named tables in an Excel workbook using drive and item IDs. Returns each table's name, columns, and style for analysis.

Instructions

Represents a collection of tables associated with the workbook. Read-only.

đź’ˇ TIP: Lists all named tables in a workbook. Each table has id, name, showHeaders, showTotals, columns, and style. Use the table name or id with other table endpoints.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topNoPage size (Graph $top). Start small (e.g. 5–15) so responses fit the model context; raise only if needed. Use $select to return fewer fields per item. For more rows, use @odata.nextLink from the response instead of a very large $top.
skipNoItems to skip for pagination. Not supported with $search.
searchNoKQL search query — wrap value in double quotes. Cannot combine with $filter.
filterNoOData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
countNoSet true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
orderbyNoSort expression, e.g. receivedDateTime desc
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
expandNoExpand related entities
driveIdYesPath parameter: driveId
driveItemIdYesPath parameter: driveItemId
fetchAllPagesNoFollow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a small $top first, then paginate or narrow with $filter/$search.
includeHeadersNoInclude response headers (including ETag) in the response metadata
excludeResponseNoExclude the full response body and only return success or failure indication
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, so the read-only nature is clear. The description adds that the tool returns table metadata (id, name, showHeaders, etc.), which is useful but not extensive behavioral context. Since annotations cover the safety profile, a score of 3 is appropriate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences and a tip, with no unnecessary words. Every sentence adds value, defining the tool's action, response structure, and a practical usage hint.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of an output schema, the description adequately explains that the response includes table objects with specific fields. The input schema covers pagination and filtering parameters. While it could mention prerequisites like needing a workbook, the overall completeness is sufficient for a list tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all 13 parameters thoroughly. The description does not add any new meaning to the parameters beyond what is in the schema, which justifies the baseline score of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Lists all named tables in a workbook' and lists the fields each table contains. It distinguishes itself from sibling tools like list-excel-table-rows (which lists rows) and list-excel-worksheets, making the purpose unambiguous with a specific verb and resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description lacks explicit guidance on when to use this tool versus alternatives, such as list-excel-table-rows or list-excel-worksheets. The tip about using table name/id with other endpoints hints at follow-on actions but does not provide when-to-use or when-not-to-use advice, leaving the AI without clear selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
