How to convert webhook json payloads to a csv log
- Step 1Collect the webhook payloads into one file — Concatenate logged events into a JSON array, or save them as NDJSON (one per line) — both formats work.
- Step 2Drop the file in the converter — Auto-detect picks the right parser; force-pick NDJSON if your log is line-delimited.
- Step 3Leave flattening on — Nested event objects become dot-notation columns ready for pivot tables.
- Step 4Open the CSV in your analysis tool — Excel, Sheets, DuckDB, or Looker Studio all read the resulting CSV directly.
Frequently asked questions
Will signatures or auth headers appear?+
Only fields present in the JSON body. Webhook signatures live in HTTP headers and aren't part of the payload — log them alongside if you need them.
Can I keep one row per nested order line?+
Not in a single pass. Flattening keeps one row per event. To explode line items into rows, pre-process the JSON in code.
How sensitive is webhook data?+
Some webhook bodies include PII or partial card data. Conversion is local — the file never leaves your browser. Still, scrub before sharing the CSV externally.
