Why Use the CSV Converter

Delimiter Detection
Comma, semicolon, tab or pipe, the tool reads the delimiter your CSV uses so columns line up correctly every time.
Encoding Kept Intact
UTF-8 and other encodings are preserved, so accented names and non-English characters survive the conversion without turning into boxes.
100% Offline
Every conversion runs on your own PC. Your data files are never uploaded, which keeps business and personal records private.

Where a CSV Converter Helps
Data and Reporting Teams
Move exports between tools that speak different formats. Pull a CSV export into Excel for analysis, or push a report out as JSON for a dashboard.
Developers and IT
Convert between CSV, JSON and XML when moving data between systems, without writing a one-off script for every file.
Accounting and Admin
Bring a bank or software CSV export into Excel cleanly, or turn a spreadsheet into a shareable PDF table for records.
Anyone With a Messy CSV

Questions
CSV Converter Questions
Drop your CSV file into Univik CSV Converter, pick Excel as the output and run it. The tool writes a clean XLSX workbook with every field in its own column and the delimiter and encoding sorted for you, so you skip the Excel import wizard and the leading-zero and scientific-notation problems it causes.
Yes. The converter turns CSV rows into structured JSON records, and it also reads JSON and flattens it back into CSV rows and columns. Both directions run in batch, so you can convert many files at once.
That happens when the delimiter is read wrong, often a semicolon file read as comma-separated. The converter detects whether your CSV uses commas, semicolons, tabs or pipes and lines up the columns correctly, so the output is never one merged column.
Yes. The tool preserves UTF-8 and other encodings, so accented names and non-English text stay intact instead of turning into boxes or question marks, which is a common problem when a CSV is opened with the wrong encoding.
Yes. Point the converter at a folder and it processes every CSV file inside in one run. Batch conversion works for all supported output formats, which saves time on large sets of files.
No. Every conversion runs on your own Windows PC and nothing is sent online. That keeps business records, personal data and any sensitive information private on your machine.
Univik CSV Converter runs on Windows 11 and Windows 10, both 64-bit, and on Windows Server. It needs .NET Framework 4.8 or higher, which most Windows PCs already have, and it works fully offline.
