- No file size restrictions, 100% in-browser
Local Browser Processing & Privacy
Traditional web converters upload your documents, snippets, or media files to remote servers. Instant CSV to JSON & Table Converter runs inside your browser tab:
Your input text and files are processed locally without uploading payloads to a processing server.
Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).
Working outputs stay in your browser tab and are released when you reset the tool or close the tab.
Frequently Asked Questions
How is this better than older conversion tools like convertcsv.com?
Microdeck is completely ad-free, parses instantly as you type without page reloads, and never uploads your private spreadsheets to remote servers.
