Export Experiment Data to Excel
Overview
export_experiment_data_to_excel transforms heterogeneous experimental data — JSON from video analysis pipelines, pandas DataFrames, time-series arrays, nested protocol outputs — into clean, human-readable Excel workbooks. The skill auto-assigns logical sheet names (e.g., Raw Data, Growth Curves, Cell Counts, Population Metrics), prepends unit and metadata annotation rows, applies consistent column widths and header styling, and emits a single .xlsx file ready for lab notebooks, ELN attachment, regulatory submission, or downstream statistical analysis. It bridges the gap between machine-generated structured data and the Excel-centric workflows that many wet-lab researchers and collaborators expect.
When to Use This Skill
Use this skill when any of the following conditions are present:
- LabOS pipeline export: Output from
extract_experiment_data_from_video, analyze_lab_video_cell_behavior, or generate_cell_analysis_charts is in JSON or tabular form and must be shared as an Excel file for collaborators or PI review.
- Multi-sheet report assembly: Several related datasets (raw counts, summary metrics, time-series curves, per-well results) must be organized into one workbook with clearly named sheets rather than scattered CSV files.
- Unit and provenance documentation: Data columns require explicit unit headers (µL, h⁻¹, µm/h, %) and annotation rows (experiment ID, date, protocol version) so recipients understand the data without reading separate metadata files.
- ELN or Benchling attachment: A Benchling ELN entry or protocols.io experiment record requires an Excel file as an attached data object; the skill produces a formatted file suitable for direct upload.
- Regulatory or audit trail: GLP/GMP or audit documentation requires data in a fixed, non-editable (or track-changes) format; Excel with frozen headers and annotation rows meets many lab compliance requirements.
- Collaborator handoff: A non-computational collaborator or external lab needs data in Excel for manual inspection, plotting in Excel/GraphPad, or import into proprietary analysis software.
- Statistical analysis prep: Data will be imported into R, SPSS, GraphPad Prism, or pandas; the skill ensures column names are valid, units are explicit, and missing values are consistently encoded (e.g.,
NA, empty, or —).
- Batch experiment export: Multiple experiments or conditions are consolidated into one workbook with one sheet per condition, or one sheet per time point, for side-by-side comparison.
Core Capabilities
1. Multi-Source Input Parsing
Ingests diverse input formats and normalizes them for Excel export:
- JSON (nested or flat): Parses JSON from
analyze_lab_video_cell_behavior, extract_experiment_data_from_video, or custom pipelines; flattens nested objects into columns; extracts timeseries, population_metrics, tracks[], events into separate logical tables
- pandas DataFrame: Direct pass-through; column dtypes preserved; datetime columns formatted for Excel compatibility
- List of dicts / list of lists: Converted to a table with optional header row; first row can be treated as headers or as data
- CSV / TSV file path: Loaded via pandas; re-exported to Excel with enhanced formatting
- Time-series arrays:
(timestamp, value) pairs or (timestamp, value1, value2, …) arrays become columns with automatic naming (Time_h, Cell_count, Confluence_pct)
- Multi-experiment bundles: A dict mapping
experiment_id → data; each experiment becomes a sheet or a grouped set of rows with an experiment_id column
2. Automatic Sheet Naming & Organization
Assigns meaningful sheet names and organizes data into logical groups:
- Schema-driven naming: When input is JSON from known LabOS skills, maps top-level keys to standard sheet names:
timeseries → "Time Series" or "Growth Curves" (if cell_count/confluence present)
population_metrics → "Population Metrics"
phenotype_counts → "Phenotype Counts"
tracks → "Cell Tracks" or "Track Data"
events → "Events"
raw / raw_data → "Raw Data"
- User override: Accepts explicit sheet-name mapping:
{"sheet_1": data1, "My Custom Sheet": data2}
- Sheet name sanitization: Truncates to 31 characters (Excel limit); replaces invalid characters (
\, *, ?, :, [, ]); ensures uniqueness by appending _2, _3 if duplicates
- Ordering: Sheets ordered by logical flow — metadata/summary first, raw data last, or user-specified order
- Multi-table per sheet: Optionally places multiple small tables (e.g., phenotype counts + key metrics) on one sheet with blank rows between them
3. Unit Headers & Annotation Rows
Prepends metadata and unit information for clarity:
- Annotation block (rows 1–N): Optional header rows before the data table:
- Row 1:
Experiment ID, Date, Protocol, Operator (or user-defined keys)
- Row 2:
Units — one cell per column, e.g., h, cells, %, µm/h, µL
- Row 3:
Description — short column descriptions for complex metrics
- Unit inference: When column names match known patterns (
*_uL, *_h, *_um_h, *_pct), auto-fills unit row; user can override via config
- Frozen panes: Freezes the annotation + header row so they remain visible when scrolling
- Comment cells: Optional Excel comments (cell notes) for columns that need extra explanation (e.g., "See Methods for formula")
4. Formatting & Styling
Applies consistent visual styling for readability:
- Header row: Bold, background color (e.g., light gray
#E0E0E0), bottom border; font size 11 pt
- Annotation rows: Italic, smaller font (9 pt), light background to distinguish from data
- Column width: Auto-sized to fit content or header, with min/max limits; numeric columns right-aligned, text left-aligned
- Number formatting:
- Floats: 2–4 decimal places by default; scientific notation for very large/small values
- Percentages:
0.0% or 0.00% for columns with pct or % in name
- Datetimes:
YYYY-MM-DD HH:MM or MM/DD/YYYY per locale
- Integers: no decimal places
- Alternating row colors: Optional zebra striping for wide tables to improve readability
- Conditional formatting: Optional — e.g., highlight cells above/below threshold, color-scale for numeric columns (green–yellow–red)
- Data validation: Optional dropdowns or value constraints for columns that should accept only specific values (e.g., phenotype names)
5. Specialized Export Modes
Handles domain-specific export patterns:
- 96-well plate layout: When data has
well or row+col columns, can render as an 8×12 grid matching physical plate layout; one sheet per plate or per time point
- Time-series long vs. wide: Long format (one row per time point per condition) or wide format (one column per condition); user selectable
- Track export: For
tracks[] with nested trajectory_um arrays, flattens to one row per track with summary stats; or exports trajectory as separate columns x_0, y_0, x_1, y_1, … for downstream plotting
- Statistical summary table: When input includes p-values, effect sizes, confidence intervals, formats as a compact summary table with appropriate precision (p < 0.001, not 0.0000001)
- Protocol step table: Converts protocol steps (from protocols.io or Benchling) into a numbered table with columns: Step, Action, Parameters, Notes
6. Output Options
Configurable export behavior:
- Single file: One .xlsx file with all sheets
- Multi-file: One .xlsx per experiment or per condition when data volume is large
- Append mode: Add new sheets to an existing workbook (e.g., append "Experiment_2" to a running lab notebook workbook)
- Timestamp in filename: Optional
experiment_2026-03-06_143022.xlsx for versioned exports
- CSV fallback: If openpyxl/xlsxwriter is unavailable, falls back to CSV export with one file per sheet and a manifest file listing sheet names and filenames
