Reads Vanta desktop exports and Vanta Connect exports. Format is detected from the column headers, so there is nothing to map. Drop several files in at once if a hole spans more than one export.
Projects and prospects are not built in. Import a reference JSON for your own ground and it is remembered on this browser, or leave the boxes blank. Export saves your current reference to share.
Nothing is preloaded. Set the elements and cut offs you want to work to, then save them against the prospect so they come back next time. A threshold in percent is converted before comparison, so a value can never be compared against the wrong unit.

The classifier out of the logging workbook, keeping its cut offs but letting you move them. A ratio splits felsic from intermediate from mafic, then a second element splits the mafic end. Readings where the ratio cannot be worked out, usually because one of the two came back below detection, fall through to the last class rather than erroring.
| Condition | Cut off | Class | Readings |

Blanks and standards are picked out of the reading stream by sample ID and held out of the background statistics. Anything matched by similarity rather than exactly is marked so you can check it. These are identification only, since a handheld cannot verify a certified gold value.
Every reading of the same puck is tracked in the order it was taken. Drift is the trend across that series as a percentage of its own mean, so it works whether or not a certified value has been entered. Add the certified values for your pXRF pucks and it will also show bias against them.
The background is kept per prospect as a pooled distribution rather than a growing pile of raw rows, so adding a batch twice cannot double count it and the percentiles stay honest. Export it to move it between machines.

Each rule fires on the last two digits of the sample number. A reserved number is consumed by its QAQC row rather than skipped, so the book stays aligned with the pad. Rules change between programs, so add and retire them as you go.
| On | Ending | Inserts | Standard to use |

Paste a submission sheet, including its header row, to check it against the insertion rules above and against the interval rules Plexer enforces on import. Works on any sheet, whether this tool built it or not.
The readings laid out the way they are read on paper, one row per reading with hole, interval and sample ID up front. Each element carries its one sigma error as a percentage and a confidence band, set in step 01. Elements use whatever unit you set in step 03, so a threshold in percent shows the element in percent. Export it to CSV and it opens straight into Excel.
