Raw CSV Exports Are Hard to Read
Database dumps and SaaS exports produce raw CSVs containing thousands of lines of unformatted text. Reviewing them requires manually importing into spreadsheets, formatting headers, creating pivot tables, and fixing misaligned columns.
Web Worker Streaming & Auto-Profiling
OpenMIS parses the CSV in a background Web Worker, detects delimiters automatically, detects data types, profiles missing value rates, and generates interactive ECharts visuals with zero wait time and strict confidentiality.
Frequently Asked Questions
Does OpenMIS handle different CSV delimiters?
Yes. PapaParse automatically detects comma, semicolon, tab, or pipe delimiters. You can also manually override the delimiter if your export uses a custom separator.
Can large CSV exports crash my browser?
OpenMIS runs CSV parsing in a dedicated HTML5 Web Worker off the main UI thread. For smooth interactive visualization, files up to 50MB and 100,000 rows are recommended.
Is CSV formula injection (DDE) prevented?
Yes. When you export or clean CSV files, OpenMIS inspects every cell string and prepends an apostrophe (') to any cell starting with =, +, -, @, \t, or \r, neutralizing spreadsheet execution risks.
