BI Analyst Toolkit
Business intelligence professionals bridge the gap between raw data and business decisions. The work involves building reports, validating data sources, managing dashboard configurations, and ensuring data quality. These free, browser-based tools handle the technical micro-tasks that arise when you are connecting to APIs, formatting data, and maintaining BI infrastructure.
JSON Formatter & Validator
Pretty-print JSON from data source APIs, BI tool exports, and semantic model definitions. The formatted view helps you understand the data structure before building reports and verify that API connections return the expected schema.
Code Diff Tool
Compare report definitions, dashboard configurations, and data model changes side by side. Essential for version control of BI assets and reviewing changes before promoting to production.
RegExp Tester
Build regex patterns for data validation rules, calculated field expressions, and text parsing in report filters. Test patterns against sample data before deploying them in your BI tool.
Color Converter
Convert brand colors between HEX, RGB, and HSL for custom report themes. Ensure charts and dashboards match corporate brand guidelines across all BI platforms.
JSON to YAML Converter
Convert BI tool export files and API configurations to YAML for version-controlled dashboard-as-code workflows. Keep report definitions under source control alongside your data models.
Timestamp Converter
Convert timestamps when debugging report refresh schedules, data warehouse load times, and API rate-limit windows. Essential for aligning report schedules with data availability.
Crontab Calculator
Validate cron expressions for scheduled report deliveries, data refresh triggers, and automated alert notifications. Preview execution times to ensure reports arrive before morning standup.
Duplicate Line Remover
Clean up dimension values, metric lists, and filter options before building reports. Duplicate entries create misleading aggregations and confusing dashboard filters.
Base64 Encoder / Decoder
Decode embedded images in report exports, inspect Base64-encoded API tokens for data source connections, and encode logos for custom report headers.
Character Counter
Check report titles, dashboard names, and metric descriptions against platform character limits. Ensure labels fit within chart space constraints for clean presentation.
URL Encoder / Decoder
Encode parameters for embedded report URLs, decode tracked links from email report distributions, and fix encoding issues in dashboard drill-through URLs.
QR Code Generator
Generate QR codes linking to live dashboards and interactive reports. Perfect for printed executive summaries, meeting room displays, and physical data posters.
