CSV/Excel Merger
Skill ImethibitishwaMerge multiple CSV/Excel files with intelligent column matching, data deduplication, and conflict resolution. Handles different schemas, formats, and combines data sources. Use when users need to merge spreadsheets, combine data exports, or consolidate multiple files into one.
This skill merges multiple CSV or Excel files, automatically handling variations in column names, schemas, and data formats. It provides intelligent column matching, data deduplication based on a primary key, and conflict resolution strategies, ultimately generating a consolidated file and a detailed report.
Documentation
- warning:Configuration & parameter referenceWhile the instructions detail a process, there are no explicit parameters, defaults, or configuration options documented for the skill itself, and no mention of environment variables or precedence order.
Versioning
- warning:Release ManagementThere is no version number declared in the SKILL.md frontmatter, package.json, or a CHANGELOG, and no GitHub releases are present. The README does not specify an install command that would require a version.
Code Execution
- info:ValidationThe example Python code suggests basic data normalization (stripping whitespace, lowercasing) but does not explicitly mention or demonstrate the use of a schema validation library for all inputs and outputs.
- info:Error HandlingThe example Python code shows basic file reading and merging but lacks explicit error handling for operations like file not found, permission errors, or malformed data, and doesn't detail structured error reporting.
Practical Utility
- info:Edge casesThe instructions mention handling different data types, missing columns, large files, and multiple primary keys, but do not explicitly detail failure modes or recovery steps for each.
Portability
- warning:Stack assumptionsThe example Python code imports pandas and uses file I/O, but there is no explicit declaration of the required interpreter (Python version) or explicit installation instructions for dependencies like pandas.

Vipanuzi vinavyofanana
Data Analysis Skill
96Use this skill when the user uploads Excel (.xlsx/.xls) or CSV files and wants to perform data analysis, generate statistics, create summaries, pivot tables, SQL queries, or any form of structured data exploration. Supports multi-sheet Excel workbooks, aggregation, filtering, joins, and exporting results to CSV/JSON/Markdown.
Excel Spreadsheet Operations
75Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When Claude needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas
XLSX Spreadsheet Skill
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
