What is CSV Studio?

CSV Studio is EverydayHub's privacy-first data workspace at everydayhub.app/CSVStudio. It bundles four studios into one app: CSV Studio, JSON Studio, XML Studio, and Excel Studio. Every operation runs client-side in your browser using Web Workers — your files never touch a server.

No account, no upload queues, and no tracking. Open a file, edit it, export it, and close the tab.

Why use a browser-based CSV editor?

Spreadsheets often contain customer records, payroll data, inventory lists, and financial exports. Uploading those files to cloud editors creates privacy and compliance risk. CSV Studio keeps processing on your device, which makes it suitable for sensitive workflows where data residency matters.

Because it runs in the browser, CSV Studio works on Windows, macOS, Linux, and mobile — without installing desktop software.

CSV Studio tools

The CSV editor includes six focused tools for everyday data tasks:

  • Viewer — Browse large CSV files with virtual scrolling and sortable columns
  • Cleaner — Trim whitespace, remove duplicates, find-and-replace values
  • Splitter — Split rows by count or split column values into new files
  • Combiner — Merge multiple CSV files with matching headers
  • Columns — Reorder, rename, hide, and compute new columns
  • Statistics — Column type detection, null counts, min/max, and unique values

Undo and redo history lets you experiment safely before exporting the final file.

JSON, XML, and Excel studios

CSV Studio is part of a unified data suite. Switch between formats from the sidebar without leaving the app:

  • JSON Studio — Format, validate, minify, and explore JSON trees
  • XML Studio — Parse, format, and inspect XML documents
  • Excel Studio — Open .xlsx and .xls files, preview sheets, and export data

Who CSV Studio is for

Analysts cleaning export files, developers inspecting API payloads, marketers merging campaign CSVs, operations teams splitting large reports, and anyone who needs spreadsheet edits without cloud uploads.

CSV Studio vs. cloud spreadsheet tools

Cloud editors require uploads, accounts, and often store files on remote servers. CSV Studio is designed for quick, private edits: open a file, transform it, download the result. It complements EverydayHub's lightweight CSV ↔ JSON converter when you need full editing workflows rather than a one-step conversion.
