Convert semicolon CSV to comma

1) Identify delimiter source first

Before conversion, confirm how the file was produced:

• Check header line length stability across first few rows.
• Confirm whether values contain commas wrapped in quotes.
• Look for semicolons inside free-text fields and preserve quote context.

2) Convert with a safe parser flow

Use your browser cleaner: set delimiter to semicolon, clean spacing, normalize quotes, then export using comma output. This minimizes parser breakage in downstream BI or spreadsheet tools.

• Run one controlled sample before full-file conversion.
• Validate row counts after conversion.
• Compare a few known rows manually before automation.

3) Prevent recurring bad exports

Build a repeatable profile that enforces one delimiter policy. Save it and reuse for the same source system.

4) Real-world checklist before you run full conversion

• Validate the delimiter on at least 50 rows in the first pass.
• Confirm row counts and header names are unchanged after conversion.
• Ensure quoted text containing commas keeps quote boundaries intact.
• Verify that numeric-like fields did not lose leading zeros.
• Export a source-cleaned sample for one human review before bulk processing.

5) Sample input/output

Raw export (semicolon delimiter):

id;date;amount;notes
12;2026-02-20;1,200;value, revised
13;2026-02-21;900;plain value

Output after conversion and quoting cleanup:

id,date,amount,notes
12,2026-02-20,"1,200","value, revised"
13,2026-02-21,900,plain value
