Powerful Spreadsheet Intelligence. Zero Cloud Ingestion.

CSV and Excel workbooks are parsed inside your browser using dedicated Web Workers. File content never traverses the public internet or external API gateways.

• Runs on user's device with zero server dependency
• SheetJS CE & PapaParse parsing in worker thread
• Multi-sheet Excel workbook tab selector
• Configurable CSV delimiter overrides (comma, tab, semicolon)

Immediately highlights null values, distinct cardinalities, min/max distributions, and identifies field types (Number, Categorical, Date, Boolean, Identifier).

• Identifies missing value percentage per column
• Detects potential primary keys and dimensions
• Column data type override with 1 click
• Calculates mean, median, min, max for numeric fields

Clean dirty data without corrupting your raw file. OpenMIS maintains an immutable snapshot and a reversible stack of operations.

• Trim whitespace to consolidate fragmented groups
• Deduplicate identical rows
• Filter noise rows by numeric or text thresholds
• Full Undo/Redo stack with transformation history

No hallucinated AI summaries. Insights are generated from pure mathematical rules and verified distributions.

• Top-N category concentration (e.g. Top 3 categories drive 68% volume)
• Outlier detection using Interquartile Range (IQR)
• Growth and decline velocity with MoM and YoY formulas
• Evidentiary calculation modal explaining every formula

Automatic visualization engine maps your fields to Bar, Line, Area, Donut, Scatter, and Metric cards based on statistical cardinality.

• Accessible table view toggle on every single widget
• Fluid resize observer with auto-scaling layout
• Color palette themes (Corporate, Ocean, Emerald, Amber)
• Top-N grouping with automatic 'Other' rollup

Customize every widget title, dimension, measure, aggregation type (SUM, AVG, MIN, MAX, COUNT), sort order, and color scheme.

• Global dashboard filters (date range, categories)
• Widget-level override filters
• Reorder, duplicate, or remove widgets with keyboard access
• Auto-saved state to IndexedDB with JSON export

Guards against Dynamic Data Exchange (DDE) formula injection by escaping dangerous characters (=, +, -, @, \t, \r) before writing CSV or XLSX files.

• Automatic apostrophe prefixing for dangerous formula cells
• Preserves legitimate negative numbers (-42) and positives
• Filtered dataset download honoring active canvas filters
• Clean print-ready CSS for boardroom PDF reports

No hidden SaaS subscriptions, compulsory logins, or tracking pixels. All data stays confined to your browser session.

• Zero tracking cookies or third-party ad scripts
• Local IndexedDB storage for offline report access
• 1-Click 'Clear Data' memory and cache wipe
• Permissive MIT open-source license
