Build and Validate Excel Workbooks
Spreadsheet changes can damage formulas, styles, macros, or workbook structure. This skill uses direct OOXML workflows and validation tools to preserve existing files.

Agent request
Review the Skillstore skill "minimax-xlsx" from https://skillstore.io/skills/minimax-ai-minimax-xlsx.md and its manifest at https://skillstore.io/api/skills/minimax-ai-minimax-xlsx/manifest. Verify the artifact. Stop and obtain explicit user consent before installing or changing files.Your Agent should still show its plan and request any confirmation required by the security policy.
Agent-readable resources
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Test it
Using "minimax-xlsx". Inspect quarterly-results.xlsx and report formula or data quality issues.
Expected outcome:
- Workbook review covering sheet structure, populated ranges, and key formulas.
- Issue list with affected sheets and cells.
- Summary statistics for important numeric columns.
Using "minimax-xlsx". Add a percent-of-total column to the Sales sheet and preserve the workbook.
Expected outcome:
An updated workbook with the new formula column, inherited styles, percentage formatting, and preserved original sheets.
Using "minimax-xlsx". Validate budget-model.xlsx after formula edits.
Expected outcome:
A validation summary covering static formula checks, available recalculation results, and remaining workbook errors.
Security Audit
High Riskv5 • 8/9/2026 Open versioned report
Most static alerts are scanner mismatches caused by OOXML namespace URIs, Markdown backticks, XML syntax, and safe argument-array subprocess calls. Confirmed risks include predictable shared temporary paths and recursive deletion of a caller-supplied output directory. Semantic review also found an agent-control instruction and unbounded processing of untrusted workbook archives.

High
Prompt Injection Attempt Detected
SKILL.md says, "Handle the request directly. Do NOT spawn sub-agents." This unrelated agent-control instruction can override the host's orchestration policy.
The quoted text directly controls agent behavior instead of describing spreadsheet processing. Its location and imperative wording are unambiguous.
High
Unbounded Workbook Archive Processing
Untrusted XLSX archives are extracted and worksheet parts are loaded without limits on member count, expanded size, compression ratio, or XML size. Crafted files can exhaust disk or memory.
The code iterates and extracts every archive member, then reads worksheet XML into memory. No resource quotas or archive expansion checks are present.
Capability review items (62)
These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.
High
Python shutil operations
shutil.rmtree(output_dir)
The CLI recursively deletes any existing caller-supplied output directory before extraction. A mistaken or attacker-influenced path can cause destructive deletion outside a dedicated workspace.

What You Can Build
Review Financial Models
Inspect assumptions, formulas, totals, formatting, and formula errors before a model is distributed.
Update Operational Workbooks
Insert budget rows, add calculated columns, and preserve the workbook layout during recurring updates.
Automate Spreadsheet Quality Checks
Run structural, formula, and style checks as part of a controlled document workflow.
Try These Prompts
Inspect a Workbook
Inspect [file.xlsx]. Summarize each sheet, important columns, formulas, missing values, and notable data quality issues. Do not modify the source file.
Create a Formatted Workbook
Create [output.xlsx] from this table: [paste data]. Add formulas for totals, apply suitable number formats, and validate the finished workbook.
Edit an Existing Model
Update [input.xlsx] and write [output.xlsx]. Add [requested rows or columns], preserve every existing sheet, and verify representative original values afterward.
Validate and Repair Formulas
Audit [model.xlsx] for missing sheets, broken references, error values, circular-reference risks, and inconsistent formatting. Repair confirmed issues and produce a validated copy.
Best Practices
- Keep the original workbook unchanged and write edits to a separate output file.
- Locate target rows and sheets by labels and relationships before changing XML.
- Run structural and formula validation after every edit.
Avoid
- Do not rebuild an existing workbook when a targeted XML edit is sufficient.
- Do not hardcode calculated values when the workbook requires formulas.
- Do not treat a successful ZIP operation as complete workbook validation.
Frequently Asked Questions
Can this skill create a workbook from scratch?
Yes. It starts from a minimal OOXML template, adds data and formulas, applies formatting, and packages the result as XLSX.
Can it preserve macros and advanced workbook features?
The direct XML workflow avoids common round-trip losses, but complex macros, pivots, charts, and relationships still require careful verification.
Does formula validation calculate every formula?
Static checks do not calculate formulas. Dynamic recalculation uses LibreOffice when it is available.
Does it support CSV and TSV files?
Yes for tabular reading and analysis. XLSX-specific formulas, styles, sheets, and relationships do not apply to plain text formats.
Will it overwrite the original workbook?
The documented workflow preserves the source and writes a separate output. Always provide distinct input and output paths.
What should I verify before delivery?
Confirm sheet names, representative original values, formulas, styles, package structure, and any recalculation errors.
