Data & Spreadsheets
Clarity from complexity.
Turn spreadsheets and raw tables into clearer information. Start with editing or cleaning, then explore formulas, insights and visual reports.
From raw rows to a useful report
Choose a CSV, spreadsheet or data visualization workflow
Start with your file format and intended outcome. A CSV cleanup, workbook formula review and data chart each need different controls; the directory connects the dedicated tools for those tasks.
Clean and prepare CSV data
Inspect rows, missing values and inconsistent formats before using the data in a chart or report.
Open Data Cleaning StudioWork with XLSX sheets and formulas
Open supported spreadsheet files, inspect cells and formulas, and save an editable copy where available.
Open XLSX EditorBuild visual data summaries
Explore columns, select chart types and review what the chosen measures actually represent.
Open Local Data VisualizerExample: review a raw CSV in CSV Viewer, clean it, then create grouped summaries in CSV Pivot Table Maker before charting. Keep the original data and check units, calculated fields and export compatibility. Optional AI helpers may require model downloads.
Before you start
Can I work with CSV and Excel spreadsheets online?
PixelOkay includes separate CSV and XLSX viewers and editors. Supported spreadsheet features, formulas and export behavior vary by tool; retain a copy of your original file.
Can AI spreadsheet tools check calculations for me?
Some tools offer optional suggestions or formula analysis, but those are not a substitute for verifying calculated results in the actual workbook or a trusted reference.

Some modes download external engines. Save originals/projects and check each tool’s resource, format and privacy limits.
Keep project or progress backups when a tool offers them. Browser storage and download behavior vary by tool and browser.
