Frequently asked questions
What exactly does this tool do to my chromatography peak table?+
It converts European comma decimals (3,14) to dot decimals (3.14). You paste the raw export, the parser detects the delimiter (comma, tab, semicolon or pipe), the transform runs, and you see the result plus a one-line summary of what changed. You can then copy the CSV or download CSV/JSON. It is deliberately one well-defined operation so the output is predictable and reproducible.
Is my instrument data uploaded anywhere?+
No. All parsing and computation happen locally in your browser with JavaScript — nothing is sent to a server. That keeps a chromatography peak table private, which matters for analytical-chemistry labs handling unpublished or confidential results, and it means the tool also works offline.
What input and output formats are supported?+
Input can be CSV, TSV, or semicolon/pipe-delimited text copied straight from your instrument software or a spreadsheet — the delimiter is auto-detected. Output is standard RFC-4180 CSV (copy or download) or a JSON array of objects keyed by the header row.
How should I sanity-check the result?+
Spot-check a few rows against your raw file, especially headers and any computed columns. This tool applies a single transform faithfully, but it can't know your specific column quirks — confirm it picked the right columns (e.g. the Cq, OD, area or A260 column) before using the output downstream.
