Drop a .dat or .opt load file and I'll set it out as a table. Nothing is uploaded.
Load File Reader
Open a Concordance .DAT or Opticon .OPT load file as a searchable table, with delimiters and encoding handled. Rows whose field count disagrees with the header are reported. Export CSV.
Good to know
- Defaults are the standard Concordance delimiters: thorn as the quote, 0x14 between fields, and 0xAE for a newline.
- Encoding can be UTF-8, UTF-16LE or Latin-1. If the text looks wrong, try another.
- This reads the load file only. It does not check that the images or natives it names exist.
Your files stay on your machine
This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.
These are the free ones — see the full suiteHow big a file can it take?
There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.
- The file is read whole and the table stops at 50,000 rows, which it says when it happens.
- Wide load files cost more than long ones, because every field is held as text.
Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
