CSV Reader X Lora (Soze)

Say you want to test every LoRA in a set against every prompt in a spreadsheet - that's rows × LoRAs worth of combinations, and normally means nesting two loops. This node's whole reason for existing, straight from the pack's own docs, is collapsing that into one counter: "the X Checkpoint/X Lora variants iterate index across rows × models, so a single counter walks every (row, checkpoint) pair." Feed it one incrementing number, and it advances through both dimensions for you.

How it works

You give it a CSV file and a LoRA sequence to walk (start_lora_name plus lora_count LoRAs from that starting point), and one index value that ticks up each run. Internally, that single index maps onto a position in the combined row × LoRA space - as it climbs, it walks through every LoRA for the current row, then advances to the next row and starts the LoRA sequence again (that's what "walks every pair" means in practice). You drive index from something that actually increments across queue executions - an INT primitive on "increment," or a range node - not a fixed value, or you'll get the same row and LoRA every single run.

The inputs and outputs that matter

• csv_filename_path (required) - your CSV.
• index (required, 0 to 1,000,000, tooltip: "The row number to read from the CSV file") - the counter driving both dimensions.
• start_lora_name (required, tooltip: "The name of the starting LoRA") - a dropdown populated from your installed LoRAs, the first one in the sequence.
• lora_count (required, 1–100, tooltip: "The number of LoRAs to iterate") - how many LoRAs from that start point to cycle through.

Outputs cover both halves of the pair: Column_1–Column_10 (up to ten columns from the current row), Entire_Line (the raw row text), Row_Count (total rows - your signal for when the CSV side has been fully walked), Lora_Full_Path, Lora_Name_Only, Lora_Index (which LoRA this particular index landed on), and status.

How to install it

ComfyUI Manager → search "ComfyUI_Soze" → install → restart. Manual:

cd ComfyUI/custom_nodes
git clone https://github.com/SozeInc/ComfyUI_Soze.git
pip install -r ComfyUI_Soze/requirements.txt

then restart. No heavy dependency - plain CSV parsing. The schema doesn't specify the expected delimiter or quoting rules beyond "CSV," so test with a small, simple comma-separated file first before trusting anything with embedded commas or quotes.

Common issues & troubleshooting

Getting the same row and LoRA forever almost always means index is wired to a static value instead of something that increments per queue run - check that first.

Row_Count is your safety rail: the schema doesn't document what happens when index runs past the end of the file, so build a stop condition around Row_Count rather than assuming the counter wraps cleanly on its own.

Wire Lora_Full_Path (or Lora_Name_Only) into your LoRA loader and the relevant Column_N into your prompt text, and once the sweep's done, this pairs well with XY Image to lay the whole comparison out as one labeled grid instead of paging through results one at a time.
